5. In front he lays down one, with (Vajasaneyi Samhita XV, 10), “Queen thou art, the Eastern region,” for a queen indeed the eastern region is;—“The divine Vasus are thine overlords,” for the divine Vasus are indeed the overlords of that region;—“Agni is the repeller of shafts,” for Agni, indeed, is here the repeller of shafts;—“The Trivrit-Stoma may uphold thee on earth!” for by the threefold hymn(-form) this one is indeed upheld on earth;—“The Ajya-shastra may support thee for steadiness’ sake!” for by the Ajya-shastra it is indeed supported on earth for steadiness’ sake;—“the Rathantara-saman for stability in the air!” for by the Rathantara-saman it is indeed established in the air;—“May the Rishis, the first-born, magnify thee among the gods!”—the Rishis, the first-born, doubtless, are the vital airs, for they are the first-born Brahman;—“with the measure, the width of the sky!”—that is, “as great as the sky is, so much in width may they broaden thee!”- 'And he, the upholder, and the overlord,'—these two are speech and mind, for these two uphold everything here;—“may they all, of one mind, settle thee, and the Sacrificer, on the back of the firmament, in the world of heaven!” as the text, so its import.
