Anyone who is a bona fide preacher of the cult of Sri Caitanya Mahaprabhu must be respectful to the real devotees of Lord Caitanya; one should not be envious, considering one preacher to be very great and another to be very lowly. This is a material distinction and has no place on the platform of spiritual activities. Krishnadasa Kaviraja Gosvami therefore offers equal respect to all the preachers of the cult of Sri Caitanya Mahaprabhu, who are compared to the branches of the tree. ISKCON is one of these branches, and it should therefore be respected by all sincere devotees of Lord Caitanya Mahaprabhu. (CC Adi 10.7 Purport)
