Sri Caitanya-caritamrta

CC Madhya-lila

“Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth.” It is very difficult to understand Kṛṣṇa, but if one tries to understand Śrīmad-Bhāgavatam through Caitanya Mahāprabhu’s bhakti cult, one will undoubtedly understand Kṛṣṇa very easily.

CC Madhya 25.270, Translation and Purport

By understanding the pastimes of Śrī Caitanya Mahāprabhu, one can understand the truth about Kṛṣṇa. By understanding Kṛṣṇa, one can understand the limit of all knowledge described in various revealed scriptures.

As Lord Kṛṣṇa states in the Bhagavad-gītā (BG 7.3):

manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye

yatatām api siddhānāṁ kaścin māṁ vetti tattvataḥ

“Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth.” It is very difficult to understand Kṛṣṇa, but if one tries to understand Śrīmad-Bhāgavatam through Caitanya Mahāprabhu’s bhakti cult, one will undoubtedly understand Kṛṣṇa very easily. If somehow or other one understands Kṛṣṇa, his life is successful. Again, as Kṛṣṇa states in the Bhagavad-gītā (BG 4.9):

janma karma ca me divyam evaṁ yo vetti tattvataḥ

tyaktvā dehaṁ punar janma naiti mām eti so ‘rjuna

“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.”
