Bhagavad Gita 4.20त्यक्त्वा कर्मफलासङ्गं नित्यतृप्तो निराश्रयः।कर्मण्यभिप्रवृत्तोऽपि नैव किञ्चित्करोति सः ॥

The same idea of inaction in action is repeated here to produce a deep impression on the minds of the aspirants. He who works for the wellbeing of the world and he who performs actions without egoism and attachment for the fruits, to set an example to the masses, really does nothing at all though he is ever engaged in activity, as he possesses the knowledge of the Self which is beyond all activity and as he has realised his identity with It.As Brahman the Absolute is selfcontained, all the desires are gratified if one realises the Self. He is ever satisfied and does not depend on anything, just as a man who has the favour of the king does not depend on the minister or the government official for anything. (Cf.IV.41)
