When the four months of the rainy season passed and still Aniruddha had not returned home, all the members of the Yadu family became much perturbed. They could not understand how the boy was missing. Fortunately, one day the great sage Nārada came and informed the family about Aniruddha's disappearance from the palace. He explained how Aniruddha had been carried to the city of Śonitapura, the capital of Bāṇāsura's empire, and how Bāṇāsura had arrested him with the nāgapāśa, even though Aniruddha had defeated his soldiers. This news was given in detail, and the whole story was disclosed. Then the members of the Yadu dynasty, all of whom had great affection for Kṛṣṇa, prepared to attack the city of Śonitapura. Practically all the leaders of the family, including Pradyumna, Sātyaki, Gada, Sāmba, Sāraṇa, Nanda, Upananda and Bhadra, combined together and gathered eighteen akṣauhiṇī military divisions into phalanxes. Then they all went to Śonitapura and surrounded it with soldiers, elephants, horses and chariots.
