Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O Maharaja Pariksit, descendant of Pandu, Sankrti had two sons, named Guru and Rantideva. Rantideva is famous in both this world and the next, for he is glorified not only in human society but also in the society of the demigods.
