|Chapter 3: Karma-yoga|
na karmanam anarambhan
naishkarmyam purusho 'snute
na ca sannyasanad eva
Not by merely abstaining from work can one achieve freedom from reaction, nor by renunciation alone can one attain perfection.
From 3.4 to 3.9 Krishna explains the active nature of the soul. Inactivity is therefore not an option. In this verse Krishna cautions against the danger of premature or immature renunciation. This is because the dormant desires for sense gratification will eventually rise in the heart of a person who has not yet been purified enough – and they would cause his fall down. Srila Prabhupada explains, "The renounced order of life can be accepted when one has been purified by the discharge of the prescribed form of duties which are laid down just to purify the hearts of materialistic men. Without purification, one cannot attain success by abruptly adopting the fourth order of life (sannyasa)."
