Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: King Indra, the leader of the demigods, inquired about the armor known as Narayana-kavaca from Visvarupa, who was engaged by the demigods as their priest. Please hear Visvarupa’s reply with great attention.
