With (Vâg. S. XXIII, 19), 'We call upon thee, the host-leader of (divine) hosts, O my true lord!' the wives walk round (the horse), and thus make amends to it for that (slaughtering): even thereby they (already) make amends to it; but, indeed, they also fan it. Thrice they walk round; for three (in number) are these worlds: by means of these worlds they fan it. Thrice again they walk round,--that amounts to six, for there are six seasons: by means of the seasons they fan it.
