Bhagavad Gita 18.1

अर्जुन उवाच |
सन्न्यासस्य महाबाहो तत्त्वमिच्छामि वेदितम् |
त्यागस्य च हृषीकेश पृथककेशिनिसूदन

Translation

Arjun said: O mighty-armed Krishna, I wish to understand the nature of sanyās (renunciation of actions) and tyāg (renunciation of desire for the fruits of actions). O Hrishikesh, I also wish to know the distinction between the two, O Keshinisudan.
