Śaṅkarācārya's commentary

They who long after success in action sacrifice to the Gods, such as Indra and Agni. The Śruti says: "He who, on the other hand, worships a separate God, thinking, 'He is separate from me and I am separate from Him' — he knows not. He is to the Devas as cattle (to men)" (Bṛ. Up. 1.4.10). For quickly is the fruit of action reaped in this world of men by those who, with selfish ends in view, sacrifice to external Gods. It is for this world of men that Vedic injunctions are meant.
