Śrīmad-Bhāgavatam · Text 1.3.44
Who is speaking and story frame
तत्र कीर्तयतो विप्रा विप्रर्षेर्भूरितेजस: ।
अहं चाध्यगमं तत्र निविष्टस्तदनुग्रहात् ।
सोऽहं व: श्रावयिष्यामि यथाधीतं यथामति ॥ ४४ ॥
tatra kīrtayato viprā
viprarṣer bhūri-tejasaḥ
ahaṁ cādhyagamaṁ tatra
niviṣṭas tad-anugrahāt
so ’haṁ vaḥ śrāvayiṣyāmi
yathādhītaṁ yathā-mati
O learned brāhmaṇas, when Śukadeva Gosvāmī recited Bhāgavatam there [in the presence of Emperor Parīkṣit], I heard him with rapt attention, and thus, by his mercy, I learned the Bhāgavatam from that great and powerful sage. Now I shall try to make you hear the very same thing as I learned it from him and as I have realized it.
