Sriman Mahaprabhu’s opinion is that Śrīmad Bhāgavatam is the spotless proof, and it contains prema-bhakti-tattva. We accept Śrīmad Bhāgavatam in that manner. We never aspire for any other literature. Prema-bhakti will be developed only by hearing Śrīmad Bhāgavatam, and thereby you will be able to conquer the unconquerable — Krishna. How is Krishna conquered? He is conquered only by bhakti.
