Lord Kṛṣṇa begot ten sons in the womb of each of His queens. Among these sons, Pradyumna was foremost, being equal to His father in all transcendental qualities. Pradyumna married Rukmī’s daughter, and from her womb Aniruddha was born. Aniruddha then married Rukmī’s granddaughter and begot Vajra, who was the only Yadu prince to survive the battle of iron clubs at Prabhāsa. From Vajra descended the remainder of the Yadu dynasty, beginning with Pratibāhu. The members of the Yadu dynasty are virtually innumerable; indeed, just to educate their children the Yadus employed 38,800,000 teachers.
