'Together with father Vaisvânara,'--for the father Vaisvânara ('common to all men'), doubtless, is the year, is Pragâpati (lord of creatures); hence he thereby propitiates the year and thus Pragâpati.--'O Agni! O Pûshan! O Brihaspati! speak forth and offer up sacrifice (pra-yag)!'--he (the Hotri), namely, will have to recite the anuvâkyâs and the yâgyâs; he therefore now propitiates those gods: do ye recite, 'do ye offer!' thus (he thereby says).
