To yoga who has renounced obligations, to knowledge, abandoned doubt,
Who is only the Self, actions do not bind, O wealth-winner.
O wealth-winner, actions do not bind one who is only the self, who has renounced obligations to yoga [and] abandoned doubt to knowledge.
Source: Milind S. Pandit
Karma does not bind one who has renounced work (by renouncing the fruits of work) through Karma-yoga; whose doubt is completely destroyed by knowledge; and who is Self-realized, O Arjuna.
Therefore, one who has renounced the fruits of his action, whose doubts are destroyed by transcendental knowledge, and who is situated firmly in the self, is not bound by works, O conqueror of riches.
