In plain words
The discus bright as a crore of suns in the hand, the serpent king for seat and for bed, the forest garland and the Kaustubha jewel: I myself am Viṣṇu. Hari, salutation to Nārāyaṇa.
Word for word
A discus equal to a crore of suns in the hand here; the king of serpents always, to sit on and to lie on; all that is worn, the forest garland and the rest and the Kaustubha: I myself am Viṣṇu. Hari, salutation to Nārāyaṇa.
