4.41

yoga-sannyasta-karmāṇaḿ
jñāna-sañchinna-saḿśayam
ātmavantaḿ na karmāṇi
nibadhnanti dhanañ-jaya

Translation

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.

4.42

tasmād ajñāna-sambhūtaḿ
hṛt-sthaḿ jñānāsinātmanaḥ
chittvainaḿ saḿśayaḿ yogam

Translation

Therefore the doubts which have arisen in your heart out of ignorance should be slashed by the weapon of knowledge. Armed with yoga, O Bharata, stand and fight.
