punaścākhyātumicchāmi bhagavanvistareṇa vai |
kathameṣyati vipratvaṃ kulaṃ me bhṛgunandana |
kaścāsau bhavitā bandhurmama kaścāpi saṃmataḥ || 35 ||

"Kusika said, 'Even this, O great ascetic, is a high boon, in my case, for thou hast been gratified by me. Let that take place which thou hast said. Let my grandson become a Brahmana, O sinless one! Indeed, let the status of Brahmanahood attach to my race, O holy one. This is the boon I ask for. I desire to once more ask thee in detail, O holy one! In what way, O delighter of Bhrigu, will the status of Brahmanahood attach to my race? Who will be my friend? Who will have my affection and respect?'"
