20. Then in the middle (he lays down one), with (Vajasaneyi Samhita XV, 19), “This one above, the boon-bestower,” the one above, doubtless, is Parjanya (the rain-god); and when he speaks of him as (being) “above,” it is because Parjanya is indeed above; and when he calls him the boon-bestower, it is because from there the boon, rain, food for creatures, is bestowed hitherwards;—“and Senajit (the conqueror of armies) and Sushena (leader of a fine army), his commander and chieftain,” these are the two winter-months;—“and the nymphs, Urvashi and Purvashcitti,”—“quarter and intermediate quarter,” said Mahitthi, but they are oblation and dakshina (priest’s sacrificial fee);—“thunder the shaft, lightning the missile,” for indeed thunder is here the shaft, and lightning the missile;—“to them be homage . . .!” the import of this has been explained.
