'The priests of the priest, of the great inspirer of devotion,'--the learned Brâhmans versed in sacred writ, truly, are the priests: it is regarding them that he says this. And 'of the great inspirer of devotion,'--the great inspirer of devotion, truly, is the sacrifice: it is regarding the sacrifice that he says this. 'The knower of rites alone hath assigned the priestly offices,' for, in performing the sacrifice, they indeed assign the priestly offices. 'Great is the praise of the divine Savitri; Hail!' Thus he offers to Savitri for his impulsion.
