CC Ādi 8.33

ore mūḍha loka, śuna caitanya-maṅgala
caitanya-mahimā yāte jānibe sakala
Word for word: 
ore — O all of you; mūḍha — foolish; loka — people; śuna — just hear; caitanya-maṅgala — the book of this name; caitanya — Lord Caitanya’s; mahimā — glories; yāte — in which; jānibe — you will know; sakala — all.
Translation: 
O fools, just read Śrī Caitanya-maṅgala! By reading this book you can understand all the glories of Śrī Caitanya Mahāprabhu.
Purport: 

Śrī Vṛndāvana dāsa Ṭhākura’s Śrī Caitanya-bhāgavata was originally entitled Śrī Caitanya-maṅgala, but when Śrīla Locana dāsa Ṭhākura later wrote another book named Śrī Caitanya-maṅgala, Śrīla Vṛndāvana dāsa Ṭhākura changed the name of his own book, which is now therefore known as Śrī Caitanya-bhāgavata. The life of Śrī Caitanya Mahāprabhu is very elaborately described in the Caitanya-bhāgavata, and Kṛṣṇadāsa Kavirāja Gosvāmī has already informed us that in his Śrī Caitanya-caritāmṛta he has described whatever Vṛndāvana dāsa Ṭhākura has not mentioned. This acceptance of Śrī Caitanya-bhāgavata by Kṛṣṇadāsa Kavirāja Gosvāmī indicates his acceptance of the disciplic succession. A writer of transcendental literature never tries to surpass the previous ācāryas.
