Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Mandhata begot three sons in the womb of Bindumati, the daughter of Sasabindu. These sons were Purukutsa, Ambarisa, and Mucukunda, a great mystic yogi. These three brothers had fifty sisters, who all accepted the great sage Saubhari as their husband.
