My dear brāhmaṇa, austerity in the form of meditation is My heart, Vedic knowledge in the form of hymns and mantras constitutes My body, and spiritual activities and ecstatic emotions are My actual form. The ritualistic ceremonies and sacrifices, when properly conducted, are the various limbs of My body, the unseen good fortune proceeding from pious or spiritual activities constitutes My mind, and the demigods who execute My orders in various departments are My life and soul.
