na hi deha-bhrta sakyam
tyaktum karmany asesatah
yas tu karma-phala-tyagi
sa tyagity abhidhiyate
It is indeed impossible for an embodied being to give up all activities. But he who renounces the fruits of action is called one who has truly renounced.
Commentary by Srila Prabhupada
It is said in Bhagavad-gita that one can never give up work at any time. Therefore he who works for Krishna and does not enjoy the fruitive results, who offers everything to Krishna, is actually a renouncer. There are many members of the International Society for Krishna Consciousness who work very hard in their office or in the factory or some other place, and whatever they earn they give to the Society. Such highly elevated souls are actually sannyasis and are situated in the renounced order of life. It is clearly outlined here how to renounce the fruits of work and for what purpose fruits should be renounced.
Commentary by Sri Visvanatha Cakravarti Thakur
Therefore, actions ordained by scripture should not be given up. It is not possible for one with a body to give up activities. Sakyam is used for the proper word sakyani. The Lord has already said that not for a moment can the person remain without doing action: na hi kascit ksanam api jatu tisthaty akarma-krd iti. (BG 3.5)
