Whilst with mind intent on Vishńu, he thus pronounced his praises, the divinity, clad in yellow robes, suddenly appeared before him. Startled at the sight, with hesitating speech Prahláda pronounced repeated salutations to Vishńu, and said, "Oh thou who removest all worldly grief, Keśava, be propitious unto me; again sanctify me, Achyuta, by thy sight."
