8. Then on the left (north) side (he lays down one), with (Vajasaneyi Samhita XV, 13), “Self-ruling thou art, the northern region,” for self-ruling that northern region indeed is; 'The divine Maruts are thine overlords,' for the divine Maruts are indeed the overlords of that region;—“Soma is the repeller of shafts,” for Soma, indeed, is here the repeller of shafts;—“The Ekavimsha-stoma may uphold thee on earth!” for by the twenty-one-fold hymn this one is indeed upheld on earth;—“The Nishkevalya-shastra may support thee for steadiness’ sake!” for by the Nishkevalya-shastra it is indeed supported on earth for steadiness’ sake;—“the Vairaja-saman for stability in the air!” for by the Vairaja-saman it is indeed established in the air;—“May the Rishis, the first-born, magnify thee among the gods . . .!” the import of this has been explained.
