SB Introduction: After this incident the Lord began to preach and propagate His Bhagavata-dharma, or sankirtana movement, more vigorously, and whoever stood against this propagation of the yuga-dharma, or duty of the age, was properly punished by various types of chastisement. Two brahmana gentlemen named Capala and Gopala, who also happened to be maternal uncles of the Lord, were inflicted with leprosy by way of chastisement, and later, when they were repentant, they were accepted by the Lord. In the course of His preaching work, He used to send daily all His followers, including Srila Nityananda Prabhu and Thakura Haridasa, two chief whips of His party, from door to door to preach the Srimad-Bhagavatam All of Navadvipa was surcharged with His sankirtana movement, and His headquarters were situated at the house of Srivasa Thakura and Sri Advaita Prabhu, two of His chief householder disciples. These two learned heads of the brahmana community were the most ardent supporters of Lord Caitanya's movement. Sri Advaita Prabhu was the chief cause for the advent of the Lord. When Advaita Prabhu saw that the total human society was full of materialistic activities and devoid of devotional service, which alone could save mankind from the threefold miseries of material existence, He, out of His causeless compassion for the age-worn human society, prayed fervently for the incarnation of the Lord and continually worshiped the Lord with water of the Ganges and leaves of the holy tulasi tree. As far as preaching work in the sankirtana movement was concerned, everyone was expected to do his daily share according to the order of the Lord.
