3.5

The vaṣaṭ-call is indeed the vessel of the gods. When he utters the vaṣaṭ-call, he thereby gratifies the deities with the vessel of the gods. He makes the secondary vaṣaṭ-call. Just as over there they repeatedly refresh horses or cattle, in the very same way they repeatedly gratify the deities when he makes the secondary vaṣaṭ-call. They say: 'They revere these very fires, the dhiṣṇyas; then why do they offer in the front one alone, why do they make the vaṣaṭ-call at the front one?' Because he makes the secondary vaṣaṭ-call with 'O Agni, enjoy the Soma!', thereby he pleases the dhiṣṇyas. They say: 'They consume uncompleted Somas whose secondary vaṣaṭ-call is not made; what, then, is the Sviṣṭakṛt portion of the Soma?' Because he makes the secondary vaṣaṭ-call with 'O Agni, enjoy the Soma!', thereby, as it were, they consume completed Somas; and that itself is the Sviṣṭakṛt portion of the Soma. He utters the vaṣaṭ-call.
