Śrīmad-Bhāgavatam · Text 12.13.19
Who is speaking and story frame
कस्मै येन विभासितोऽयमतुलो ज्ञानप्रदीप: पुरा
तद्रूपेण च नारदाय मुनये कृष्णाय तद्रूपिणा ।
योगीन्द्राय तदात्मनाथ भगवद्राताय कारुण्यत-
स्तच्छुद्धं विमलं विशोकममृतं सत्यं परं धीमहि ॥ १९ ॥
kasmai yena vibhāsito ’yam atulo jñāna-pradīpaḥ purā
tad-rūpeṇa ca nāradāya munaye kṛṣṇāya tad-rūpiṇā
yogīndrāya tad-ātmanātha bhagavad-rātāya kāruṇyatas
tac chuddhaṁ vimalaṁ viśokam amṛtaṁ satyaṁ paraṁ dhīmahi
I meditate upon that pure and spotless Supreme Absolute Truth, who is free from suffering and death and who in the beginning personally revealed this incomparable torchlight of knowledge to Brahmā. Brahmā then spoke it to the sage Nārada, who narrated it to Kṛṣṇa-dvaipāyana Vyāsa. Śrīla Vyāsa revealed this Bhāgavatam to the greatest of sages, Śukadeva Gosvāmī, and Śukadeva mercifully spoke it to Mahārāja Parīkṣit.
