namo dvi-sirsne tri-pade
namah—I offer my respectful obeisances unto You; dvi-sirsne—who have two heads; tri-pade—who have three legs; catuh-srngaya—who have four horns; tantave—who expand; sapta-hastaya—who have seven hands; yajnaya—unto the yajna-purusa, the supreme enjoyer; trayi—the three modes of Vedic ritualistic ceremonies; vidya-atmane—the Personality of Godhead, the embodiment of all knowledge; namah—I offer my respectful obeisances unto You.
I offer my respectful obeisances unto You, the Supreme Personality of Godhead, who have two heads [prayaniya and udayaniya], three legs [savana-traya], four horns [the four Vedas] and seven hands [the seven chandas, such as Gayatri]. I offer my obeisances unto You, whose heart and soul are the three Vedic rituals [karma-kanda, jnana-kanda and upasana-kanda] and who expand these rituals in the form of sacrifice.
