Bhagavad Gita: Acts only for the bare necessities of life and not affected by sinful reactions (Bhagavad Gita, Text 21, Ch 4, Transcendental Knowledge)

Nirasir yata-cittatma
tyakta-sarva-parigrahah
sariram kevalam karma
kurvan napnoti kilbisam

(Bhagavad Gita, Text 21, Ch 4, Transcendental Knowledge)

Meaning: Such a man of understanding  acts with mind and intelligence perfectly controlled, gives up all sense of proprietorship over his possessions, and acts only for the bare necessities of life.Thus working, he is not affected by sinful reactions.

*** A divine conscious person does not expect good or bad results in his activities. His mind and intelligence  are fully controlled. He knows  that because he is  part and parcel of the supreme, the part played by him, as a part and  parcel of the whole, is not his own activity but is only being done through him by the supreme.
