I offer my respectful obeisances unto You, the Supreme Personality of Godhead, who have two heads [prāyaṇīya and udāyanīya], three legs [savana-traya], four horns [the four Vedas] and seven hands [the seven chandas, such as Gāyatrī]. I offer my obeisances unto You, whose heart and soul are the three Vedic rituals [karma-kāṇḍa, jñāna-kāṇḍa and upāsanā-kāṇḍa] and who expand these rituals in the form of sacrifice.
