In the first eleven verses of the Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī thus discusses Lord Caitanya Mahāprabhu as Śrī Kṛṣṇa Himself, the Supreme Personality of Godhead, and Lord Nityānanda as Balarāma, the first expansion of Kṛṣṇa. Then in the twelfth and thirteenth verses he describes Advaitācārya, who is another principal associate of Lord Caitanya Mahāprabhu’s and an incarnation of Mahā-Viṣṇu. Thus Advaitācārya is also the Lord, or, more precisely, an expansion of the Lord. The word advaita means “nondual,” and His name is such because He is nondifferent from the Supreme Lord. He is also called ācārya, teacher, because He disseminated Kṛṣṇa consciousness. In this way He is just like Caitanya Mahāprabhu. Although Lord Caitanya is Śrī Kṛṣṇa Himself, He appeared as a devotee to teach people in general how to love Kṛṣṇa. Similarly, although Advaitācārya is the Lord, He appeared just to distribute the knowledge of Kṛṣṇa consciousness. Thus He is also the Lord incarnated as a devotee.
In the pastimes of Lord Caitanya, Kṛṣṇa is manifested in five different features, known as the pañca-tattva, to whom Śrīla Kṛṣṇadāsa Kavirāja offers his obeisances in the fourteenth verse of the Caitanya-caritāmṛta. Kṛṣṇa and His associates appear as devotees of the Supreme Lord in the form of Śrī Kṛṣṇa Caitanya, Śrī Nityānanda Prabhu, Śrī Advaitācārya, Śrī Gadādhara Prabhu and Śrīvāsa Prabhu. In all cases, Caitanya Mahāprabhu is the source of energy for all His devotees. Since this is the case, if we take shelter of Caitanya Mahāprabhu for the successful execution of Kṛṣṇa consciousness, we are sure to make progress. In a devotional song, Narottama dāsa Ṭhākura sings, “My dear Lord Caitanya, please have mercy upon me. There is no one who is as merciful as You. My plea is most urgent because Your mission is to deliver all fallen souls, and no one is more fallen than I. Therefore I beg priority.”
With verse 15, Kṛṣṇadāsa Kavirāja Gosvāmī begins offering his obeisances directly to Kṛṣṇa Himself. Kṛṣṇadāsa Kavirāja was an inhabitant of Vṛndāvana and a great devotee. He had been living with his family in Katwa, a small town in the district of Burdwan, in Bengal. He worshiped Rādhā-Kṛṣṇa with his family, and once when there was some misunderstanding among his family members about devotional service, he was advised by Nityānanda Prabhu in a dream to leave home and go to Vṛndāvana. Although he was very old, he started out that very night and went to live in Vṛndāvana. While he was there, he met some of the Gosvāmīs, principal disciples of Lord Caitanya Mahāprabhu. He was requested to write the Caitanya-caritāmṛta by the devotees of Vṛndāvana. Although he began this work at a very old age, by the grace of Lord Caitanya he finished it. Today it remains the most authoritative book on Caitanya Mahāprabhu’s philosophy and life.
