Thereupon he addresses (the Hotri) for the recitation on the havis to the manotâ deity. The reason why he addresses him for the recitation on the havis to the manotâ deity is this. All the deities draw nigh to the victim while it is immolated, thinking, 'My name he will choose, my name he will choose!' for the animal victim is sacrificial food for all deities. The minds (manas), then, of all those deities are, fixed upon (ota) that victim; those (minds of theirs) he thereby satisfies, and thus the minds of the gods have not drawn nigh in vain. For this reason he addresses him for the recitation on the havis to the manotâ deity.
