In this chapter the author has fully discussed the reason for the descent of Śrī Caitanya Mahāprabhu. The Supreme Personality of Godhead, Lord Śrī Kṛṣṇa, after displaying His pastimes as Lord Kṛṣṇa, thought it wise to make His advent in the form of a devotee to explain personally the transcendental mellow reciprocations of service and love between Himself and His servants, friends, parents and fiancees. According to the Vedic literature, the foremost occupational duty for humanity in this Age of Kali is nāma-saṅkīrtana, or congregational chanting of the holy name of the Lord. The incarnation for this age especially preaches this process, but only Kṛṣṇa Himself can explain the confidential loving service performed in the four principal varieties of loving affairs between the Supreme Lord and His devotees. Lord Kṛṣṇa therefore personally appeared, with His plenary portions, as Lord Caitanya. As stated in this chapter, only for that purpose did Lord Kṛṣṇa appear personally in Navadvīpa in the form of Śrī Kṛṣṇa Caitanya Mahāprabhu.
