nibadhnanti dhanan-jaya

Word for word: 
yoga — by devotional service in karma-yoga; sannyasta — one who has renounced; karmanam — the fruits of actions; jnana — by knowledge; sanchinna — cut; samsayam — doubts; atma-vantam — situated in the self; na — never; karmani — works; nibadhnanti — do bind; dhanam-jaya — O conqueror of riches.

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who acts in devotional service, renouncing the fruits of his actions, and whose doubts have been destroyed by transcendental knowledge, is situated factually in the self. Thus he is not bound by the reactions of work, O conqueror of riches.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who follows the instruction of the Bhagavad-gita, as it is imparted by the Lord, the Personality of Godhead Himself, becomes free from all doubts by the grace of transcendental knowledge. He, as a part and parcel of the Lord, in full Krishna consciousness, is already established in self-knowledge. As such, he is undoubtedly above bondage to action.
