[He lays down the Ashâdhâ, with Vâg. S. XIII, 26] 'Thou art Ashâdhâ, the conquering,' for the gods thereby conquered the Asuras,--'conquer the enemies! conquer the hostile!' as the text, so the meaning;--'thou hast a thousand energies: do thou speed me!' a thousand means all: thus, 'thou hast all energies, do thou speed me!' When he has 'settled' it, he pronounces the Sûdadohas on it: the significance of this has been explained.
