सर्वकर्माणि मनसा संन्यस्यास्ते सुखं वशी ।नवद्वारे पुरे देही नैव कुर्वन्न कारयन् ॥
sarvakarmāṇi manasā saṃnyasyāste sukhaṃ vaśīnavadvāre pure dehī naiva kurvanna kārayan
The embodied soul perfectly controlling its nature, having renounced all its actions by the mind (inwardly, not outwardly), sits serenely in its nine-gated city neither doing nor causing to be done.
Gītā 5·13That equality, impersonality, peace, joy, freedom do not depend on so outward a thing as doing or not doing works. The Gita insists repeatedly on the difference between the inward and the outward renunciation, tyāga and saṁnnyāsya. The latter, it says, is valueless without the former, hardly possible even to attain without it, and unnecessary when there is the inward freedom.
