Bhagavad Gita · Chapter 5: Renunciation in Action

Bhagavad Gita 5.13

sarvakarmāṇi manasā saṃnyasyāste sukhaṃ vaśī | navadvāre pure dehī naiva kurvanna kārayan ||

Having given up all actions in the mind, the self-controlled dweller in the body rests happily in the city of nine gates, neither acting nor causing action.

Modern context

The body is pictured as a city with nine gates: two eyes, two ears, two nostrils, the mouth, and the two openings below. The self lives in this city as its lord, at ease, while the city's business goes on around it. The important words are 'in the mind'. The renunciation is inward and the body keeps working. What is given up is the sense of being the doer and the one who makes things happen.
