He (the Adhvaryu) offers with (Vâg. S. VII, 3), 'Self-made thou art,' for, this graha being his (Yagña's) out-breathing, it is indeed made by itself, born of itself: hence he says, 'Self-made thou art;'--'for all powers, divine and earthly,'--for it is born of itself for all creatures;--'May the mind obtain thee!'--the mind being Pragâpati, he thereby means to say, 'may Pragâpati obtain thee!' 'Hail! thee, O well-born, for Sûrya!' thus he utters the second (or inferior) 'Hail!' with regard to a subsequent (or higher; the highest) deity.
