CC Madhya 11.103, Translation and Purport

The same principles can be applied to demoniac persons, even though they be in the sampradāya of Lord Śrī Caitanya Mahāprabhu. Without receiving the Lord’s special power, one cannot preach His glories all over the world. Even though one may celebrate himself as a learned follower of Śrī Caitanya Mahāprabhu, and even though one may attempt to preach the holy name of the Lord all over the world, if he is not favored by Śrī Caitanya Mahāprabhu he will find fault with the pure devotee and will not be able to understand how a preacher is empowered by Lord Caitanya. One must be considered bereft of the mercy of Śrī Caitanya Mahāprabhu when he criticizes the Kṛṣṇa consciousness movement now spreading all over the world or finds fault with this movement or the leader of the movement.
