So far, Shri Krishna gave us a checklist of factors that could disturb our equanimity: joy, sorrow, gain and loss. Let’s say, we detect that one of these factors has presented itself to us. What should we do? He gives a beautiful example from the world of nature to address this point.

Whenever a tortoise senses danger, he withdraws his limbs into his shell. The shell is strong enough to withstand any adverse situation. And once that situation passes, he brings his limbs back into the world. Similarly, if we detect that an object, person or situation is about to disturb our equanimity, Shri Krishna advises us to bring our intellect into the picture, and completely withdraw our attention from that object, person or situation.

In one commentary on this topic, we learn that most animals have one sense organ as their weakness. The deer has sound, the elephant has touch, the moth has sight (fire), the fish has taste, and the bee has smell as its weakness. So for example, if a moth sees fire, it loses all control and flies straight into the fire. However, human beings have all five senses as their weakness, making this technique all the more important.

The most practical application of this technique is dieting. If we have a sweet tooth like we saw earlier, and we see a large slice of black forest chocolate cake in front of us, we have to apply the “tortoise technique” and move some steps away from that cake. It also means that we do not keep large stocks of chocolates, cakes etc. in our house because we may be tempted very easily.

Here’s another related point. In India, many aspects of spiritual practices are embedded in our customs, but sometimes we do not realize their significance. We may have noticed a sculpture of a tortoise outside many Indian temples, which is an instruction to withdraw our worldly matters and enter the temple with a devotional mindset. But instead of doing so, we tend to whisper about worldly matters into the tortoise’s ear, which is exactly the opposite of the original intent.
