This chapter explains that Lord Caitanya is the Supreme Personality of Godhead Kṛṣṇa Himself. Therefore, the Brahman effulgence is the bodily luster of Lord Caitanya, and the localized Supersoul situated in the heart of every living entity is His partial representation. The puruṣa-avatāras are also explained in this connection. Mahā-Viṣṇu is the reservoir of all conditioned souls, but, as confirmed in the authoritative scriptures, Lord Kṛṣṇa is the ultimate fountainhead, the source of numerous plenary expansions, including Nārāyaṇa, who is generally accepted by Māyāvādī philosophers to be the Absolute Truth. The Lord’s manifestation of prābhava and vaibhava expansions, as well as partial incarnations and incarnations with delegated powers, are also explained. Lord Kṛṣṇa’s ages of boyhood and youth are discussed, and it is explained that His age at the beginning of youth is His eternal form.
