Bg 2.39
esa te ’bhihita sankhye
buddhir yoge tv imam srnu
buddhya yukto yaya partha
karma-bandham prahasyasi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Thus far I have described this knowledge to you through analytical study. Now listen as I explain it in terms of working without fruitive results. O son of Prtha, when you act in such knowledge you can free yourself from the bondage of works.
