śrīgaruḍamahāpurāṇam- 3

iti rudrābjajo viṣṇoḥ śuśrāva brahmaṇo muniḥ /
vyāso vyāsādahaṃ vakṣyehaṃ te śaunaka naimiṣe //

The glorious Garuḍa Mahāpurāṇa — 3
Sūta said:
Thus the sage born from the lotus [seated upon] Rudra heard from Viṣṇu, [and] Vyāsa [heard] from Brahmā.
From Vyāsa, I shall speak to you, O Śaunaka, in the Naimiṣa [Forest].
