Śrīmad-Bhāgavatam · Text 3.25.2
Who is speaking and story frame
न ह्यस्य वर्ष्मण: पुंसां वरिम्ण: सर्वयोगिनाम् ।
विश्रुतौ श्रुतदेवस्य भूरि तृप्यन्ति मेऽसव: ॥ २ ॥
na hy asya varṣmaṇaḥ puṁsāṁ
varimṇaḥ sarva-yoginām
viśrutau śruta-devasya
bhūri tṛpyanti me ’savaḥ
Śaunaka continued: There is no one who knows more than the Lord Himself. No one is more worshipable or more mature a yogī than He. He is therefore the master of the Vedas, and to hear about Him always is the actual pleasure of the senses.
