Śaṅkarācārya's commentary

Knowledge of the Lord is itself a sacrifice. Worshipping by this sacrifice of wisdom, others (the Brahma-niṣṭhas, those devoted to Brahman) adore Me, having abandoned all other forms of worship. And that knowledge varies thus: some worship with the knowledge of the real truth that 'One, verily, is the Para-Brahman.' Some worship with the knowledge that the Lord Viṣṇu Himself exists as different beings, as the sun, the moon and the like. Others worship Him — who exists in all forms — as the All-faced, thinking that the one Lord exists in all the different forms, with his face on all sides.
