He also declares that the right and full comprehension of the mystery of his births and work on earth confers upon us nirvana, so that rebirth occurs no more. This is because it is not possible for a man to understand the mystery unless he has completely liberated himself from the chains of passion and acquired entire concentration. He has learned to look beneath the shell of appearances that deceives the unthinking mind. This brings us to a rock upon which many persons fall to pieces. It is personality.
Personality is always an illusion, a false picture hiding the reality inside.
No person is able to make his bodily environment correspond exactly to the best that is within him, and others therefore continually judge him by the outward show. If we try, as Krishna directs, to find the divine in everything, we will soon learn not to judge by appearances, and if we follow the advice given in this chapter to do our duty without hope of reward and without trimming ourselves with a desired result in view, the end will be peace. Krishna then adverts to various systems of religious practice, and shows Arjuna that they all lead at last, but after many births, to him, by reason of the tendency set up. The different schools are taken up in a few sentences. After enumerating all, not only the performance but also the omitting of sacrifice, he shows Arjuna that spiritual knowledge includes all actions and burns to ashes the binding effects of all work, conferring upon us the power to take nirvana by reason of emancipation from the delusion that the lower self was the actor.
