Undesirable, desirable, and mixed — threefold is the fruit of action that accrues after death to those who do not relinquish, but never to those who renounce.
अनिष्टमिष्टं मिश्रं च त्रिविधं कर्मणः फलम् |
भवत्यत्यागिनां प्रेत्य न तु संन्यासिनां क्वचित् ||१८-१२||

The Bhagavad Gita, translated and commentated by S. Radhakrishnan, is one of the most scholarly and accessible English renderings of Hinduism's most beloved scripture — the dialogue between Arjuna and Lord Krishna on the battlefield of Kurukshetra. Radhakrishnan, philosopher and statesman, brings both rigorous intellectual insight and genuine spiritual depth to his translation and notes. This edition is treasured for its ability to illuminate the Gita's universal spiritual teaching across cultural and philosophical boundaries.
You have a right to action alone, never to its fruits. Do not let the fruits of action be your motive, nor let your attachment be to inaction.
कर्मण्येवाधिकारस्ते मा फलेषु कदाचन |
मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ||२-४७||
A saint also has two wings — one in the form of God-knowledge and the other in the form of his own deeds. Without God-knowledge, action is blind, and without action, God-knowledge is lame.
