The opulence of the demons, who are generally known as the enemies of the demigods, was protected by the talents and tactics of Śukrācārya, but Viśvarūpa, who was most powerful, composed a protective prayer known as the Nārāyaṇa-kavaca. By this intelligent mantra, he took away the opulence of the demons and gave it to Mahendra, the King of heaven.
