Bhagavad Gita, Chapter 2, Verse 39

The wisdom of Self-realisation has been declared to you. Now hear the wisdom of Yoga, endowed with which, O son of Prithâ, you shall break through the bonds of Karma.

You've heard the theory. Now here's how to actually act on it, in a way that stops adding weight to what you carry.

Krishna marks a real shift here, from explaining what the soul is to teaching how to actually work with that understanding. Acting from this place is what starts to loosen karma's grip, rather than tightening it.
