papracchāṅgirasaṃ vīra gautamaḥ saṃśitavrataḥ || 4 ||

"Bhishma said, 'O thou of great splendour, the following enumeration of the sacred waters on the Earth was made by Angiras. Blessed be thou, it behoveth thee to listen to it for thou shalt then earn great merit. Once on a time, Gautama of rigid vows, approaching the great and learned Rishi Angiras endued with tranquillity of soul, while he was dwelling in a forest, questioned him, saying,--O illustrious one, I have some doubts regarding the merits attaching to sacred waters and shrines. So I desire to hear thee discourse on that topic. Do thou, therefore, O ascetic, discourse to me. What merits are earned by a person in respect of the next world, by bathing in the sacred waters on the Earth, O thou of great wisdom? Do thou expound to me this truly and according to the ordinance.'
