And so with the several deities. 'May he offer the favourite dainties of butter-drinking gods!' thereby he refers to the fore-offerings (prayâga) and after-offerings (anuyâga), for, assuredly, the butter-drinking gods (represent) the fore-offerings and after-offerings.--'May he offer Agni the Hotri's favourite dainties!' thereby he refers to Agni as Hotri; for after the gods had set apart this oblation for him, they still further propitiated him by this (formula), and invited him to his favourite dainty: this is the reason why he thus enumerates.
