Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 5

Sanskrit:

श्रीनारद उवाचनत्वा भगवतेऽजाय लोकानां धर्मसेतवे ।वक्ष्ये सनातनं धर्मं नारायणमुखाच्छ्रुतम् ॥ ५ ॥

ITRANS:

śrī-nārada uvācanatvā bhagavate ’jāyalokānāṁ dharma-setavevakṣye sanātanaṁ dharmaṁnārāyaṇa-mukhāc chrutam

Translation:

Śrī Nārada Muni said: After first offering my obeisances unto Lord Kṛṣṇa, the protector of the religious principles of all living entities, let me explain the principles of the eternal religious system, of which I have heard from the mouth of Nārāyaṇa.

Purport:

The word aja refers to Kṛṣṇa, who explains in Bhagavad-gītā (4.6), ajo ’pi sann avyayātmā: “I am ever existing, and thus I never take birth. There is no change in My existence.”
