In the prior shloka, Shri Krishna advised the meditator to detach the mind from sense objects, and to control desires by checking unwanted thoughts. In this shloka, Shri Krishna goes deeper into the topic of focusing attention on one thought. He says that the meditator should use his intellect to withdraw the mind from all material thoughts in order to focus the mind on the one thought : “I am the self”.
 
In the third chapter, we had encountered the hierarchy of our personality where we saw that the mind is higher than the senses, and the intellect is higher than the mind. What does it mean for the meditator? It means that even though the mind is hard to control, our intellect has the power to rein it in. In other words, the meditator should use the intellect to control the mind.
 
The mind likes to be busy. It hops from one thought to another at lightning fast speeds. Once we withdraw the mind from the senses, the mind gets restless because it cannot run after sense objects. In order to keep busy, it starts thinking about the past and the future. So therefore, Shri Krishna asks us to use our intellect to rein in the mind. This withdrawal is called “buddhi uparamet” in the shloka.
 
How does one do that? Let’s take dieting as an example. Imagine that our doctor has asked us to go on strict diet for 2 weeks. Our first step is to control the senses by not keeping any undesirable food in the house. When this happens, the mind will continuously think about food, and tempt the body to do undesirable things, e.g. go out of the house to get fatty food and so on. The mind becomes agitated and restless, which is a recipe for disaster.
 
At this point, we use our intellect that has received the doctor’s instructions to check the mind. We think : “I respect the doctor. Therefore, mind, stop contemplating undesirable food since it will have negative consequences for me”. When we think this thought, we can control the mind’s rush into food-related thoughts.
 
Similarly during meditation, we can withdraw the mind using the intellect. We need to have an intellect that has read and heard about the eternal essence. It understands that any thought other than “I am the self” does not have a place in meditation. Each time an unwanted thought comes, we should use the intellect to gently but firmly shift focus from that thought and put the mind back into the main thought of “I am the self”.
 
Shri Krishna says that this method could take weeks, months or years. Therefore, he asks us to do it “shanaih shanaih” or slowly slowly, with great fortitude and patience. We should constantly meditate over the thought : “ I am the self”. Other than this thought, there should be no other thought. Each time the mind strays, we should not think that we have failed and get dejected. We should again bring the mind back slowly to the one main thought.
 
When done correctly, we generate a lot of energy will radiate from our personality. This “tapas” or energy was always within us, but used to leak out through our mind and sense organs.
 
Now, the mind has another issue. It moves from thought to thought with great speed. This is taken up in the next shloka.
 
Footnotes
1. Meditation on the thought that “I am the self” is called “sajaatiya vritti”
2. Any thought other than “I am the self” is called “vijaatiya vritti” or thought about an object 3. These undesirable thoughts create the notion that “I am not the self, I am the experiencer”
4. We have to negate these undesirable thoughts during meditation

Bhagavad Gita Verse 24, Chapter 6

sankalpaprabhavaankaamaanstyaktvaa sarvaanasheshataha |
manasaivendriyagraamam viniyamya samantataha || 24 ||

 
Totally discarding all desires born out of thought projections, withdrawing the mind from sense objects everywhere.
 
sankalpa : thought projections
prabhavaan : born from
kaamaan : desires
tyaktvaa : discarding
sarvaan : all
asheshataha : totally
manasaa : mind
indriyagraamam : sense objects
viniyamya : withdrawing
samantataha : everywhere
 
In this and the next shloka, Shri Krishna gives us a method for dealing with one of the biggest challenges in meditation : uncontrolled desires. He says that in order to fulfill the goal of keeping the mind established in the self, we have to completely withdraw the mind from all sense objects and tackle desires at their root.
 
As we have seen in the “ladder of fall” in the second chapter, a thought is born as soon as we begin brooding or daydreaming over an object, person or situation towards which we have raaga (attraction) or dvesha (hatred). The more time we spend brooding on the object, the more force is gathered by the thought, just like a snowball gathering momentum.
 
It is this brooding over objects that we like or hate that has to be checked. Only this restraint will stop desires in their tracks. But to pull this off, we have to follow a multi-pronged approach. First, we have to be aware of our thinking process so that we can stop the brooding the instant it starts. It is just like stopping any phone calls or outside interference when we are in an important meeting. Next, we have to apply this technique to all types of brooding or daydreaming, not just to objects we hate. Finally, we have to constantly examine our likes and dislikes so that we can develop dispassion towards them.
 
Foremost around “desire-generators” are sense objects. Our sense organs are programmed to rush towards objects that they like, and rush away from things that they dislike. While they rush, they drag our mind along, causing distraction and agitation. That is why it is advised to meditate in a clean and quiet place so that the sense organs cannot come into contact with anything and distract us. Gradually, as we get more proficient in meditation, we should ensure that the sense organs do not take in strong impressions that can pop up later in meditation. For example, if we love oranges, then we should be careful not to eat an orange just before meditation, otherwise the mind will keep thinking about the orange.
 
Now, once the mind has been withdrawn from the senses, it will seek an outlet for the outward force that used to rush out towards sense objects. If this force is not provided with a suitable outlet, we will get into trouble. So what should we do with all the latent energy that is stored up? Shri Krishna discusses this point in the next shloka.
 

Bhagavad Gita Verse 23, Chapter 6

tam vidyaadyuhkhasaiyogaviyogam yogasanngitam |
sa nischayena yoktavyo yogonirvinnachetasaa || 23 ||

 
You should know the definition of yoga as that which severs connection with sorrow. You should engage in yoga with firm conviction and a non-despondent mind.
 
tam : that which
vidyaat : you should know
duhkha : sorrow
saiyoga : connection
viyogam : sever
yoga : yoga
sanngitam : definition
saha : that
nischayena : firm conviction
yoktavyaha : should engage in
yogaha : yoga
anirvinna: not despondent
chetasaa : mind
 
Shri Krishna motivates and inspires the meditator to attain perfection in meditation in this shloka. Only through meditation can the meditator completely sever all sorrows. He urges the meditator to follow the path of meditation with a firm and unwavering determination. No obstacles should deter the meditator from his goal.
 
We are introduced to yet another definition of yoga in this shloka. In the second chapter we saw two definitions of yoga: yoga is equanimity, and yoga is dexterity in action. Here, yoga is defined as “duhkha saiyoga viyoga”. Let us examine what this means.
 
Sorrow has an intimate relationship or connection with our live. We do get glimpses of happiness, but this is due to the degree of sorrow declining temporarily. This connection is termed as “dukha saiyoga”. We never lose this connection with sorrow throughout our life. Shri Krishna says that the yoga of meditation is the only means by which we can sever or separate this connection with sorrow. This is why the yoga is meditation is defined here as “duhkha saiyoga viyoga”.
 
In other words, if we have perfected ourselves in meditation, sorrows can never touch us. Even though we cannot stop sorrows from approaching us, we will not associate with them ever again after meditation. This capability comes as a result of the fixity of mind developed through meditation. So in addition to progressing in our spiritual journey, meditation gives us something which we continually seek on the material level as well – freedom from sorrows.
 
Now, Shri Krishna says something that he has not said anywhere else in the Gita. He says that we must make a firm determination to attain the state of the perfected meditator. He emphasizes that the state of the perfected meditator is the goal that we should aim towards. It is like a parent telling his child that he should focus on obtained his graduate degree. It implies that the child will put effort in school, high school and college, all the way until he gets his graduate degree. If each part of the curriculum is followed, the goal is attained easily.
 
Similarly, the Gita gives us a curriculum for attainment of liberation. It introduces us to the eternal essence in the second chapter. In the third chapter, it explains the method of giving up the sense of “mine” through karma yoga. In the fourth and fifth chapter, it explains the method of giving up the sense of doership i.e. “I am the doer” through karma sanyaasa. When the sense of I and mine is given up, our mind is then ready to get established in the understanding that the eternal essence is our own self through meditation.
 
Having said this, Shri Krishna is extremely pragmatic. He knows that this goal is not easy. It is going to take a long time. We will encounter obstacles in the way that may demotivate us or make us despondent and frustrated. So therefore, he says that we should not let the mind become despondent. Each time we encounter an obstacle that pushes us off the path of meditation, we get up and continue, again and again.
 
What are these obstacles and how to deal with them? This topic is taken up in the next shloka.
 

Bhagavad Gita Verse 22, Chapter 6

yam labdhvaa chaaparam laabham manyate naadhikam tataha |

yam : that
labdhvaa : having obtained
cha : and
aparam : no other
laabham : gain

adhikam : superior
tataha : than that
yasmin : in which
sthithaha : established

vichaalyate : agitated by
 
Elaborating further on the joy attained by the perfected meditator, Shri Krishna says that once the meditator gets this joy, he does not ascribe any importance to any other joy in the world. The joy of meditation becomes paramount. Also, this joy protects the meditator from the shocks of worldly life. Having gained the joy of meditation, he does not get agitated by any sorrow whatsoever.
 
As we saw earlier, any joy obtained in the material world is temporary. If someone becomes a manager, he aspires to become a senior manager. Once he becomes a senior manager, he experiences joy for some time, but then he aims for a so-called larger joy: he wants to become a director. And so the cycle continues.
 
We continually aim for greater and greater joys. In other words, we are always planning for future enjoyment. There will never come a point in life when we can say “yes, now my life is fulfilled”. Shri Krishna says that only meditation will give sense of true fulfillment and everlasting joy, incomparable to any worldly joy that we have experienced. Any worldly joy will pale in comparison to this joy. When one wins a lottery that pays millions, one does not go seeking pennies.
 
Next, Shri Krishna says that the person who becomes established in this joy of meditation is shielded from the impact of the most troublesome sorrows. Now, attainment of the joy in meditation does not mean that magically, all our sorrows will vanish. Till our human body exists, joy and sorrow will exist as well. But meditation will give us an armour that will protect us from all worldly sorrows. The inner strength provided by meditation will make us “shock proof”.
 
Let us imagine that we hear extremely disturbing news. What is our reaction typically? Our mind generates thoughts at a breakneck speed. If the sorrow is about a loss of a person, the storehouse of the mind (chitta) generates anxiety-ridded thoughts about the future (what will I do now, how will I survive, how will I adapt etc), memories of the past (it was so nice back in the day when I knew this person), and regrets (I should have done this). These are just a sample of the thousands of thoughts that the mind generates when learning of a disturbing event. For most of us, these thoughts destabilize us. But the meditator’s mind has become “set” in the eternal essence, it never loses its stability.
 
However, wee have to be careful before we give so much credit to the practice of meditation. Plain meditation without understanding, in other words, meditation without learning the content of the Gita thus far, does not give us this result. But if our intellect has diligently studied about the eternal essence – that it is beyond birth and death, that it is changeless, that it cannot be destroyed and so on – and our mind has become established in the eternal essence through meditation, the multitude of thoughts that hit our mind fail to destabilize us. We become like a rock that remains steady in a storm, not the tree that gets uprooted.
 
So therefore, meditation gives us the best of both worlds. It gives us joy independent of any future sorrow, and also protects us from the impact of heavy sorrows. In the next shloka, Shri Krishna concludes the sub-topic of the joy of meditation
 

Bhagavad Gita Verse 21, Chapter 6

sukhamaatyantikam yattadbuddhigraahyamateendriyam |
vetti yatra na chaivaayam sthitashchalati tattvataha || 21 ||

 
That infinite joy which is comprehended by the intellect but is beyond the senses, when he experiences that state and is established in it, he does not move away from his essence.
 
sukham : joy
aatyantikam : infinite
yat : that
tat : that
buddhigraahyam : comprehended by the intellect
ateendriyam : beyond the senses
vetti : experiences
yatra : in that state
na : does not
cha : and
eva : ever
ayam : he
sthitaha : established
chalati : move away
tattvataha : in his essence
 
Previously, Shri Krishna explained that the perfected meditator taps into a source of permanent joy once he detaches the mind from the sense organs and connects it to his self. In this shloka, he elaborates on the nature of that joy. He says that this joy is infinite and is comprehended only by the intellect. Also, he says that once we are established in this joy, no external circumstance will knock us or take us away from this state.
 
Let us examine the nature of this joy. Shri Krishna says that it is aatyantikam or infinite. Now, the material world is an expert in giving us infinite sorrow. There are moments in our life when the degree of sorrow is low, and we tend to think that this is joy whereas in reality it is just a lower grade of sorrow. Any new object, person or situation that we encounter carries within it the seed for innumerable sorrows. But the joy that one gets from the self is infinite.
 
Why is the joy from the self infinite? All our worldly joys are dependent on external situations. For some of us, a perfect climate makes us happy, causing us to become sad if the climate changes. For some of us, a certain person makes us happy, so we become dependent on that person and consequently feel sad if that person leaves us. We keep creating subsets in the world: I like A, which means I don’t everything that is not A. But here’s the problem; A is finite and temporary. The joy experienced in the self is independent of all external situations that are temporary in nature. That is why it is infinite.
 
Another characteristic of this joy is that it is beyond the comprehension of the senses. Just like we cannot catch a satellite TV signal with a regular antenna, our senses cannot catch this joy. It is of a different wavelength altogether. It is only comprehended by our intellect, which operates at a much higher level than our mind and senses.
 
As an example, consider two teenagers who are at a party where everyone else is enjoying a cigarette. Both of them are offered a cigarette by their friends. The sense organs are reporting the same information to both the teenager’s intellects – that cigarette smoking is enjoyable and that all their friends are doing it. One teenager accepts the offer and takes a puff. But the other teenager has a refined intellect and it “sees” that this will only lead to sorrow in the end. In the same way, the intellect experiences joy that the senses cannot experience.
 
Shri Krishna further goes on to say that once the perfected meditator is established in this joy, he will never deviate from it. It is like a child learning that 2+2 = 4. Once he has internalized this teaching, it stays with him throughout his life. Similarly, once the perfected meditator realizes this self as his true nature, he will not feel the need to take on any other role or identification for the purpose of fulfillment.
 

Bhagavad Gita Verse 20, Chapter 6

yatroparamate chittam niruddham yogasevayaa |
yatra chaivaatmanaatmaanam pashyannaatmani tushyati || 20 ||

 
When the mind is quietened through restraint by engaging in yoga, and when, beholding the self in the self, the self is content.
 
yatra : when
uparamate : quietened
chittam : mind
niruddham : removal
yogasevayaa : by engaging in yoga
yatra : when
cha : and
eva : only
aatmanaa : in the self
aatmaanam : the self
pashyan : beholds
aatmani : in the self
tushyati : content
 
Shri Krishna further elaborates on the state of the perfected meditator in this shloka. He says that the perfected meditator severs all connections of his mind with material objects, and established a connection to the self or aatmaa during meditation. When the connections with the material objects are severed, he achieves a level of satisfaction never achieved with material objects. The big difference here is that the satisfaction is from within, not from without.
 
Imagine a 100 watt bulb that is connected to a generator. The generator cannot produce more than 10 watts. Moreover, the generator is defective so even the 10 watts that it produces is intermittent. The bulb will be temporarily satisfied, but will never achieve complete satisfaction. Now, imagine that the bulb finds out that it was inside a power plant all along. When it disconnects itself from the faulty generator, and connects itself to the power plant, it will immediately experience unlimited power. Moreover, this power will be consistent and long-lasting.
 
Similarly, Shri Krishna says that the satisfaction that our mind achieves from the material world is limited and temporary. The only way to gain unlimited and permanent happiness is to connect our mind to the self or aatmaa. But this happens only when we first disconnect the mind from material objects. The state of the mind when it has disconnected from material objects, and is ready to settle into the self, is called uparamate in the shloka.
 
Withdrawal from the material world is not easy. It is the outcome of following a disciplined spiritual curriculum. First, we have to develop discrimination or viveka by strengthening our intellect through reading and listening about the eternal essence through scriptures. This enables us to develop dispassion or vairagya towards the material world. Dispassion starts turning the mind away from material objects, leading to withdrawal from the material world. It is like our attitude towards toys versus a child’s attitude – we have dispassion, the child does not.
 
So therefore, when the mind has fully turned inward, and has settled into the aatmaa or the self, we experience a deep and lasting level of satisfaction and bliss. But what exactly is meant by the mind settling into the self? It is when the only thought that remains is that “I am the aatmaa” or “I am the eternal essence”. All other thoughts about the world, people, objects, situations and so on have gone away.
 
Having gained this everlasting bliss and satisfaction, what does the meditator do? Shri Krishna explains this next.
 

Bhagavad Gita Verse 19, Chapter 6

yathaa deepo nivaatasthato nengate sopamaa smritaa |
yogino yatachittasya yunjato yogamaatmanaha || 19 ||

 
Just like a lamp in a windless place does not flicker, this state is comparable to the yogi, having controlled the mind, who engages his self in yoga.
 
yathaa : just like
deepaha : lamp
nivaatasthataha : in a windless place
na : does not
ingate : flicker
saa : this (state)
upamaa : comparison
smritaa : has been said
yoginaha : of the yogi
yatachittasya : who has controlled the mind
yunjato : engages
yogam : yoga
aatmanaha : with his self
 
The state of the meditator’s mind is beautifully explained with a classic illustration or “upamaa” by Shri Krishna in this shloka. He compares the mind of a meditator to the flame of a lamp that is burning in a windless room. Just like the flame is unwavering due to absence of wind, so too is the mind of a meditator steady due to absence of desire.
 
If we compare the focused mind to a steady flame, then we need to understand how to prevent to mind from succumbing to the winds of desire. If desires exist, we may be able to temporarily stabilize the mind, but it will eventually get destabilized due to a thought generated by a desire. Presence of desire indicates absence of detachment or vairagya. The only cure is to increase our level of detachment towards the world.
 
The intense level of detachment that is needed for meditation is not an alien concept. When people get extremely absorbed in watching TV, they temporarily develop detachment towards everything else. If we call them for dinner, or if the doorbell rings and so on, these external occurences do not even register in their minds. It again depends on what we give importance to.
 
Now let us examine another aspect of the lamp illustration. According to Vedaanta, seeing an inert object is a 2 step process. First, our mind creates a mental picture of the object. Next, the aatman or self shines a light on that picture, just like a torch does. Only when this light is shined do we come to know that “this is a mango” or “this is a car” and so on.
 
But when we meditate on the self, the second step does not happen because we are not focusing our attention on an inert object. We are focusing on the self, which illuminates itself. It is like shining a torch on the sun – the torch is useless. The self is like the candle since it does not require anything else to illumine it, to shine a light on it. This is another point made in the illustration of the flame.
 
So therefore, when our focus and concentration reaches its peak, and when the target of meditation becomes our own aatmaa or self, it is the culmination of meditation. It is the state of samaadhi. This state is further elaborated upon in the forthcoming shlokas.
 

Bhagavad Gita Verse 18, Chapter 6

yada viniyatam chittamaatmanyevaavatishyate |
nihspruhaha sarvakaamebhyo yukta ityuchyate tadaa || 18 ||

 
When the controlled mind, indifferent towards all objects, is established only in the self, then such a person is called a yogi.
 
yada : when
viniyatam : controlled
chittam : mind
aatmani : in the self
eva : only
avatishyate : is established
nihspruhaha : indifferent towards
sarvakaamebhyo : all objects
yuktaha : that yogi
iti : in this manner
uchyate : is called
tadaa : at that time
 
In this key shloka within the sixth chapter, Shri Krishna gives us a way to evaluate ourselves with regards to attaining perfection in meditation. He says that only when one can establish the mind in the self, and not in material objects of the world, is one fit to be called a meditator. There is a lot of depth and meaning in this shloka. The next few shlokas go deeper into its meaning.
 
For most of us, it is the thoughts about the material world that become the major obstacle in meditation. These thoughts are generated by vaasanaas, which are latent desires and cravings. When we experience or entertain materials object in the mind, we create subtle impressions or vaasanaas in our mind, like a camera, that “this object/person/situation is good”. The mind then regurgitates these impressions in the form of thoughts. The part of the mind that stores these impressions is also known as the “chitta”.
 
A desire is a thought that says “I have not experienced something, I want to experience it”. A craving is a thought that says “I already had a good experience, but I want it to experience it again”. It is these 2 types of thoughts that do not allow us to sit down in meditation, because they take the mind outward. Depending on the proclivities of our sense organs, impressions are recorded deeply or superficially. Stronger impressions generate stronger thoughts, pulling the mind outward forcefully.
 
Shri Krishna says that when the mind has gone beyond generating desires and cravings, only then does proper meditation happen. When the mind gets established in the self, at that time, this person is considered as perfected, integrated and established in meditation. He is fit to be called a yogi. It will only happen with a very well firmly controlled mind, which is pure and free from all kinds of cravings and desires.
 
Next, let us examine the question of where should the mind be established once it has stopped turning outward. Shri Krishna says that the mind should get established in the aatmaa or the self. But, in an earlier shloka, he had asked us to meditate on his form. What does this mean?
 
Shri Krishna says that there is no difference. He is our self. In fact, he is the self of all beings. This is the great revelation of the scriptures. If we choose to meditate on his form, that is fine. If we choose to meditate on the formless brahman, the eternal essence, that is fine too. It is usually easier to meditate on the form for beginner seekers. But it is extremely important that we have extreme regard and love towards the Ishta Devata, the form of Ishvara that we chose to meditate on. It could be Vitthala, Rama, Krishna – any deity. Meditation is not a mechanical activity, it needs uncompromising support from the body, mind and intellect. If the mind does not take pleasure in meditation, it will not happen.
 
Furthermore, the mind will settle in the self only when we make meditation our top priority. In other words, all other activities in the world should take lower priority. Otherwise, they will show up in meditation. Our job is to do just that. The mind will settle in the self automatically once we do so. It is like a youngster in the house trying to study for an exam while the TV, internet and music system are on. His attention will never go to studying because it is being dragged in several directions. He needs to first switch all the other things off.
 
Next, Shri Krishna explains the state of a perfect meditator through an illustration.

Bhagavad Gita Verse 17, Chapter 6

yuktaahaaravihaarasya yuktacheshtasya karmasu |
yuktasvapnaavabodhasya yogo bhavati duhkhahaa || 17 ||

 
One who has regulated his intake and movements, his conduct in action, his sleep and wakefulness, his sorrows are eliminated through yoga.
 

yukta : regulated
aahaara : intake
vihaara : movement
asya : one who conducts
yuktacheshtasya : one who is well behaved
karmasu : in actions
yukta : regulated
svapna : sleep
avabodhasya : one who is awake
yogaha : yoga
bhavati : are
duhkha : sorrow
haa : eliminate
 
In several places within the Gita, Shri Krishna explains a point by highlighting both its positive and negative aspects. Previously, he advised the seeker against pursuing extensive austerities using the body. In this shloka, he urges us to lead a well balanced and regulated life so that our body can support our spiritual endeavours. He says that one who has a well regulated diet, exercise, conduct and sleep is fit to become a meditator. Meditation destroys sorrow when one leads a regulated life, but it can very well cause sorrow if one does not.
 
As we saw earlier, Shri Krishna advises us to monitor the quantity and quality of our food intake. We should be constantly aware of what we are eating, how often we are eating it, what will be the impact on our meditation and so on. On similar lines, the level of daily activity conducted by our body should be appropriate with regards to our health, job and so on. If we lead mostly sedentary lives, then we should undertake the right level of exercise so that meditation does not make the body less active. If we lead very active lives, then we need to ensure that our body is calm and rested when we attempt to meditate.
 
Furthermore, the quality of our actions also determines success in meditation. If we have the habit of getting into fights with people, we will not be able to meditate properly because the fight will pop up during meditation. Similarly, if we watch a lot of tv or read a lot just before meditation, those inputs will manifest as thoughts and disrupt the meditation. The need to have the appropriate amount of sleep is also re-emphasized.
 
Broadly speaking, we have to decide what takes priority in our life. If material pursuits take priority, then there always will be excuses and reasons why our meditation cannot happen properly. But if meditation becomes the primary priority, then not only will we progress on the spiritual path, but the well-regulated life that results out of the discipline the we gain becomes a welcome addition.
 

Bhagavad Gita Verse 16, Chapter 6

naatyashnatastu yogosti na chaikaantamanashnataha |
na chaati svapnasheelasya jaagrito naiva chaarjuna || 16 ||

When we begin to think that we are progressing in meditation, we may begin to impose severe hardships on the body just because we have seen some others do it. Shri Krishna, in this shloka and the next one, dispels many of these misconceptions. Alternately, we may go in the other direction and begin to neglect the body. In this regard, he advocates a balanced and moderate lifestyle towards achieving our spiritual goals.
 
First let us examine the imposition of severe hardships on the body. Shri Krishna says that meditation will not be easy for one who constantly deprives his body of food and sleep. If the body is deprived of food for a long period of time, where will the mind go when we sit in meditation? It will go to food. The same thing will happen if we forcibly deprive the body of sleep. The minute we close our eyes to meditate, sleep will take over the body. Such hardships become obstacles in meditation.
 
Before the Buddha achieved enlightenment, he went through a phase where he deprived his body of food. When his body began to look like a skeleton, and when he realized that he was almost about to die of starvation, he came to the conclusion that such severe hardships do not in any way accelerate the process of enlightenment. One cannot torture the very instrument that one uses to attain liberation. Like a perfectly tuned musical instrument, the strings should not be too loose or too tightly wound.
 
The other extreme is living life improperly by overeating and oversleeping. Besides the health problems associated with overeating, the additional strain put on the digestive system will draw the mind’s attention away from meditation. Where meditation aims to negate association with the body, overeating pulls the meditator back to the body. Also, oversleeping makes the body dull and taamasic. Instead of meditation uplifting the meditator to a higher level of sattva, oversleeping will also pull the meditator down.
 
So therefore, any deviation from treating the body with care and moderation is not just an obstacle in the spiritual path, it also is an obstacle in any worldly activities. Shri Shankaraachaarya provides a simple formula for moderating our eating habits. He says that one should have a sense of how big one’s appetite is, and then divide it into four parts. Two parts of that appetite should be filled with solid food, one part with liquid and one part should be left empty.
