Verse 2.4.185

Sanskrit text, Unicode transliteration, Word-for-word and English translation of verse 2.4.185:

एवं भगवता तेन श्री-कृष्णेनावतारिणा ।
न भिद्यन्तेऽवतारास् ते नित्याः सत्याश् च तादृशाः ॥ १८५ ॥

evaṃ bhagavatā tena śrī-kṛṣṇenāvatāriṇā |
na bhidyante'vatārās te nityāḥ satyāś ca tādṛśāḥ || 185 ||

evam–thus; bhagavatā–from the Lord; tena–by Him; śrī-kṛṣṇena–by Śrī Kṛṣṇa; avatāriṇā–from the source of all incarnations; na bhidyante–are nondifferent; avatārāḥ–incarnations; te–they; nityāḥ–eternal; satyāḥ–real; ca–and; tādṛśāḥ–similarly.

Bhagavān Śrī Kṛṣṇa is avatārī, the source of all avatāras, so all incarnations are nondifferent from Him. As the source is eternal and real, so are the incarnations.

Commentary: Dig-darśinī-ṭīkā with Bhāvānuvāda

(By Śrīla Sanātana Gosvāmī himself including a deep purport of that commentary)

Finishing his secondary point, Śrī Nārada now comes back to the original topic of discussion. It is stated in Śrīmad-Bhāgavatam (1.3.28), “kṛṣṇas tu bhagavān svayam–Kṛṣṇa is the Supreme Personality of Godhead Himself.” Nārada intends to establish through this evidence that Śrī Kṛṣṇa’s glories are greater than the glories of all the incarnations. However, the incarnations are also eternal and real like Him. He is concluding this last point with this verse beginning with evam. Badrī-nātha Śrī Nārāyaṇa and other incarnations are nondifferent from avatārī Śrī Kṛṣṇa, Lord of Goloka. Thus, They also are nitya (eternal) and satya (real).
