The fact is that both Kṛṣṇa and Lord Caitanya are the original Personality of Godhead. Therefore no one should try to separate Lord Caitanya from Śrī Kṛṣṇa. In His form of Śrī Kṛṣṇa, He is the supreme enjoyer, and in His form of Lord Caitanya, He is the supreme enjoyed. No one can be more superexcellently attractive than Śrī Kṛṣṇa, and no one but Śrī Kṛṣṇa can enjoy the supreme form of devotion, Śrīmatī Rādhārāṇī. All Viṣṇu forms but Śrī Kṛṣṇa lack this ability. In Caitanya-caritāmṛta (Ādi-līlā 4.82) it is said that Śrīmatī Rādhārāṇī is the only personality who can infuse Govinda with transcendental pleasure. Thus Śrīmatī Rādhārāṇī is the chief of all the damsels of Vraja who love Govinda, the Supreme Personality of Godhead, Śrī Kṛṣṇa.
"Please rest assured that I have nothing to hide from you," Lord Caitanya told Rāmānanda. “Even if I do try to hide something from you, you are such an advanced devotee that you can understand all My secrets. I request that you please keep them secret and do not disclose them to anyone. If they were revealed, everyone would consider Me a madman. The facts I have disclosed to you cannot be understood by materialistic people. Were they to hear of them, they would simply laugh at Me. But you can understand these secrets; please keep them to yourself. From a materialistic point of view, a devotee in the ecstasy of love for Kṛṣṇa is mad. Both you and I are thus just like madmen. So please don’t disclose these facts to ordinary men. If you do, they will surely laugh at Me.”
