48. Narration of the onset of the disease of leprosy upon Kṛṣṇa's son Sāmba, arising from Kṛṣṇa's curse due to disrespect toward Nārada; in Kāśī, to remedy that, he constructs a pool in his own name, and through the performance of austerity his disease ceases; and narration of the māhātmya of Sāmbāditya together with the māhātmya of the pool. 215 1
