Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: Bhadrasrava, the son of Dharmaraja, rules the tract of land known as Bhadrasva-varsa. Just as Lord Siva worships Sankarsana in Ilavrta-varsa, Bhadrasrava, accompanied by his intimate servants and all the residents of the land, worships the plenary expansion of Vasudeva known as Hayasirsa. Lord Hayasirsa is very dear to the devotees, and He is the director of all religious principles. Fixed in the topmost trance, Bhadrasrava and his associates offer their respectful obeisances to the Lord and chant the following prayers with careful pronunciation.
