Then the sage, thinking of the past, addressed the Daityas for their well-being :—“Vâmana has deprived you of all your realm by measuring it with his three strides, and has made Bali a captive. Besides, He has killed Jambhâsura and Virochana. In course of the twelve battles, the Devas have killed most of your powerful members, by their various stratagems. Very few of you are left now, therefore follow my advice and cease fighting for sometime. I shall teach you a useful contrivance. I will go to acquire the spell of victory from Śiva, and, after acquiring those powerful charms from him, shall make you victorious in your fight with the Devas.”—71-75.
