Commentary
Naishkarmya Siddhi is the state where one practically does everything that must be done, and yet does “nothing.”
The term “renunciation” in this context refers to sannyāsa, which involves the act of withdrawing from worldly engagements and affairs. Sannyāsa typically entails retiring to a solitary place to wholeheartedly dedicate oneself to the pursuit of God and Self-realization.
