And whatever (gift) people offer to him, thereon he (the Adhvaryu) makes him pronounce the text, 'Bestow this much, O Soma, bring more!' for Soma indeed it is that appropriates for the consecrated whatever people offer to him: when he says, 'Bestow this much, O Soma,' he means to say, 'Bestow this much on us, O Soma;' and by 'Bring more,' he means to say, 'Fetch more for us!'--'The divine Savitri, the bestower of wealth, hath bestowed wealth on us;' whereby that (gift) comes to be impelled by Savitri with a view to (further) gifts.
