Bhagavad Gita 4.21

nirāśīr yata-cittātmā

tyakta-sarva-parigrahaḥ

śārīraṁ kevalaṁ karma

kurvan nāpnoti kilbiṣam

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.
