Chapter 4: Jnana Karma Sannyasa Yoga
knowledge and action
Krishna says this teaching is ancient and had been lost over time. He explains that whenever right living declines he comes into the world to restore it, and he describes how a person can act fully without being bound by the action. The chapter also praises knowledge as the purest of offerings and warns about the doubting mind.
Knowing why you act changes what the action does to you.
