4.20 त्यक्त्वा having abandoned, कर्मफलासङ्गम् attachment to the fruits of action, नित्यतृप्तः even content, निराश्रयः depending on nothing, कर्मणि in action, अभिप्रवृत्तः engaged, अपि even, न not, एव verily, किञ्चित् anything, करोति does, सः he.Commentary: 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)
