Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami replied: My dear King, when the order carriers of Yamaraja were baffled and defeated by the order carriers of Visnu, they approached their master, the controller of Samyamani-puri and master of sinful persons, to tell him of this incident.
