Krishna is the singular, supreme controller with no equal—accepting this truth is the foundation of all Vedic knowledge.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Ādi-līlā 7.7 — March 9, 1974, Māyāpur 740309CC-MAYAPUR [31:42 Minutes] CcAdi-07.007_740309CC-MAYAPUR Pradyumna: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [Prabhupāda and devotees repeat] [leads chanting of verse] svayaṁ bhagavān kṛṣṇa ekale īśvara advitīya, nandātmaja, rasika-śekhara [Cc. Ādi 7.7] [leads chanting of synonyms] [break] [02:11] Translation: "Kṛṣṇa, the reservoir of all pleasure, is the Supreme Personality of Godhead Himself, the supreme controller.
No one is greater than or equal to Śrī Kṛṣṇa..." [loud talking in background]
Prabhupāda: [aside:] Stop this. Pradyumna: "...yet He appears as the son of Mahārāja Nanda." Prabhupāda: [noise continues] [aside:] Stop. Svayam bhagavān kṛṣṇa. Kṛṣṇas tu bhagavān svayam [SB 1.3.28].
Whatever Kavirāja Gosvāmī is speaking—not out of his own whimsical way—whatever he's speaking, he's following the paramparā system. That is Vaiṣṇavism, or ācārya. Ācāryavan puruṣo veda [Chāndogya Upaniṣad 6.14.2]. [people continue talking] [aside:] Stop this. Unless we accept the ācārya in the paramparā system, we cannot understand things as they are. It is not possible.
So Kavirāja Gosvāmī, he's describing this Caitanya-caritāmṛta strictly according to the verdict of the śāstras. His statement is that Kṛṣṇa is the original Personality of Godhead. Svayam bhagavān kṛṣṇa. Bhagavān is person; Bhagavān is not imperson.
Brahmeti paramātmeti bhagavān iti śabdyate [SB 1.2.11]. First realization of the Absolute Truth by speculative knowledge is impersonal effulgence of the Lord, which is called brahma-jyotir. Then next realization is Paramātmā, the localized aspect of the Supreme Personality of Godhead. But realization of Kṛṣṇa, that is the ultimate realization.
Svayam bhagavān kṛṣṇa. Bhagavān means six opulences. Nobody is richer than Bhagavān, nobody is stronger than Bhagavān, nobody is more beautiful than Bhagavān, nobody is wiser than Bhagavān, and nobody is more renouncer than Bhagavān. That is Bhagavān. Aiśvaryasya samagrasya vīryasya yaśasaḥ śriyaḥ [Viṣṇu Purāṇa 6.5.47].
