Bhagavatapurana 5.4.12

5.4.12

iti bhāgavata-dharma-darśanā nava mahā-bhāgavatās teṣāṃ sucaritaṃ bhagavan-mahimopabṛṃhitaṃ vasudeva-nārada-saṃvādam upaśamāyanam upariṣṭād varṇayiṣyāmaḥ //

11&12. Kavi, Hari, Antariksha, Prabudha, Pippalayana, Avirhotra, Drumida, Chamasa, and Karabhajana; these nine who showed to the world what the duties of the votaries are, were great devotees of Lord Hari; and their history which, imbued with the glory of the Lord, leads to tranquility and engenders devotion,--we shall describe later on (in the eleventh Skandha) in the form of conversation of Vasudeva and Narada.
