śākalyas tat-sutaḥ svāṁ tu
pañcadhā vyasya saṁhitām
The son of Māṇḍūkeya, named Śākalya, divided his own collection into five, entrusting one subdivision each to Vātsya, Mudgala, Śālīya, Gokhalya and Śiśira.
jātūkarṇyaś ca tac-chiṣyaḥ
virajebhyo dadau muniḥ
The sage Jātūkarṇya was also a disciple of Śākalya, and after dividing the saṁhitā he received from Śākalya into three parts, he added a fourth section, a Vedic glossary. He taught one of these parts to each of four disciples — Balāka, the second Paila, Jābāla and Viraja.
cakre vālāyanir bhajyaḥ
kāśāraś caiva tāṁ dadhuḥ
Bāṣkali assembled the Vālakhilya-saṁhitā, a collection from all the branches of the Ṛg Veda. This collection was received by Vālāyani, Bhajya and Kāśāra.
According to Śrīla Śrīdhara Svāmī, Vālāyani, Bhajya and Kāśāra belonged to the Daitya community.
