“Avikampena yoga”, the unwavering, unshakeable yoga, is defined by Shri Krishna as knowing that Ishvara is the cause of everything, and that everything originates from Ishvara. Those who have established themselves in this yoga are “budhaa”, they are wise. They only worship or contemplate upon Ishvara, remaining unaffected by the ups and downs in life.
Imagine an adult and a child walking inside a haunted house within an amusement park. Though both of them see and hear the same things, they have different reactions. The child thinks that the ghosts and the eerie noises are real and becomes afraid. The adult knows that everything inside is fake, it is unreal. So enjoys the thrill of the haunted house without being afraid.
The difference between the adult and the child is that the adult has knowledge about the cause of the ghosts and the noises. Similarly, Shri Krishna says that one who knows Ishvara as the cause of everything will develop an extremely positive attitude towards life. He will take failures as learning opportunities, not as triggers for depression. He will never question why something bad happened to him, knowing that it is a result of his prior actions.
One who has developed such an outlook towards life will worship Ishvara at all times. This is indicated by the worlds “maam bhajante”. He will experience sorrow only if he forgets that Ishvara is the cause of everything. When one has understood that Ishvara, as the cause of everything, also is the ultimate goal, then they become totally immersed in Ishvara, as described in the next shloka.
