Pragâpati said to Agni, 'I will perform sacrifice with thee: I will lay hands upon thee (as a victim).'--'Nay,' said he, 'speak unto man!' He said to man, 'I will perform sacrifice with thee: I will lay hands upon thee.'--'Nay,' said he, 'speak unto the cattle!' He said to the cattle, 'I will perform sacrifice with you: I will lay hands upon you.'--'Nay,' said they, 'speak unto the moon!' He said to the moon, 'I will perform sacrifice with thee: I will lay hands upon thee,'--'Nay,' said he, 'speak unto the sun!' He said to the sun, 'I will perform sacrifice with thee: I will lay hands upon thee.' 'So be it!' said he; 'but seeing that those liked it not (to be slaughtered), what, then, shall become mine that now is with these?'--'Whatsoever thou mayest desire,' he said.--'So be it,' he replied. He laid hands upon him, and this is that animal of his seized (for sacrifice). When slaughtered, it swelled, and by means of those Âprî-hymns, he appeased it; and inasmuch as, by means of these Âprî-hymns, he appeased it, they are called Âprîs. And let him, for that reason, say of the slaughtered animal, 'Let it lie for a moment!' As great as the world is which he gains by performing the horse-sacrifice, so great a world does he gain by this (animal sacrifice).
