Bhagavad Gita Verse 18.2

श्रीभगवान् बोले — कितने ही पण्डित जन तो काम्य कर्मों के त्याग को संन्यास समझते हैं तथा दूसरे विचार कुशल पुरुष सह कर्मों के फल के त्याग को त्याग कहते हैं

The Blessed Lord replied: If one entirely gives up all selfish motives, desires and actions, this is called true RENUNCIATION, and he who has given up all desires for rewards for all work he has accomplished, is considered by Me to have totally SURRENDERED from the material way of life.
