The first mandate that He issued to Prabhu Nityānanda and Haridāsa was this: "Go, friends, go through the streets of the town, meet every man at his door and ask him to sing the name of Hari with a holy life, and then come and report to Me every evening the result of your preaching." Thus ordered, the two preachers went out and met Jagāi and Mādhāi, two most abominable characters. These two insulted the preachers on hearing Mahāprabhu's mandate, but were soon converted by the influence of bhakti (devotion) inculcated by their Lord.
The people of Nadia were now surprised. They said, "Nimāi Paṇḍita is not only a gigantic genius, but He is certainly a missionary from God Almighty." From this time to His twenty-third year, Mahāprabhu preached His principles not only in Nadia but in all the important towns and villages around His city. In the houses of His followers He showed miracles, taught the esoteric principles of bhakti and sang His saṅkīrtana with other bhaktas. His followers in the town of Nadia commenced to sing the holy name of Hari in the streets and bazaars. This created a sensation and roused different feelings in different quarters. The bhaktas were highly pleased. The smārta brāhmaṇas became jealous of Nimāi Paṇḍita's success and complained to Chand Kazi against the character of Caitanya, claiming it was un-Hindu. The Kazi came to Śrīvāsa Paṇḍita's house and broke a mṛdaṅga (khola drum) there and declared that unless Nimāi Paṇḍita ceased to make noise about His queer religion he would be obliged to enforce Mohammedanism on Him and His followers.
