In Chapter 3, Shri Krishna explains to a confused Arjuna that though knowledge may seem superior to action, it is imperative that both be practised. Step by step, Shri Krishna shows how the path of action is a means to the end and what happens to those who do not act. Action when practiced without attachment to its result, purifies the mind and integrates the personality. This makes the mind receptive to the knowledge that leads to Self-realisation.In Chapter 4, an all out effort is made by Krishna to bring home to Arjuna that the Lord himself, the author of the Vedas, had been asserting the same old Truth and nothing new.
The 4th chapter indicates the greater path of Gyana Yoga, the "Path-of-Knowledge"which is the only main arch-way through which all pilgrims must pass in order to reach the Temple of the Self. Upto this archway, seekers living in different psychological and intellectual domains may walk their own "paths", but the main gate is Gyana Yoga which all must pass to have Darshana at the glorious altar
