Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O King, another son of Maharaja Priyavrata, Hiranyareta, was the king of this island. He divided it into seven parts, which he delivered to his seven sons according to the rights of inheritance. The King then retired from family life to engage in austerities. The names of those sons are Vasu, Vasudana, Drdharuci, Stutyavrata, Nabhigupta, Vivikta and Vamadeva.
