vivasvatas ca dve jaye
samjña chaya ca rajendra
ye prag abhihite tava
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O King, I have previously described [in the Sixth Canto] the two daughters of Visvakarma, named Samjña and Chaya, who were the first two wives of Vivasvan.
