Bhagavad Gita 9.28

So, your action will have no result, either good or bad; but, through the spirit of renunciation, you will come to Me and be free.

शुभाशुभफलैरेवं मोक्ष्यसे कर्मबन्धनैः।
संन्यासयोगयुक्तात्मा विमुक्तो मामुपैष्यसि॥

śubhāśubhaphalairevaṃ mokṣyase karmabandhanaiḥ|
saṃnyāsayogayuktātmā vimukto māmupaiṣyasi||
