Verse 4.7
कभाश यिाक ु ृष्णं मोणगन् णत्रणवधभ इतय ् षाभे ॥ ७ ् ॥
karmashuklakrishnnam yoginah trividham itaresham
Works are neither black nor white for the Yogis; for others they are threefold, black, white, and mixed.
When the Yogi has attained to that state of perfection, the actions of that man, and the Karma produced by those actions, will not bind him, because he did not desire them. He just works on: he works to do good, and he does good, but does not care for the result, and it will not come to him. But for ordinary men, who have not attained to that highest state, works are of three kind, black (evil actions), white (good actions), and mixed.
