Unless one surrenders unto the lotus feet of the Personality of Godhead, it is sure and certain that one will be bewildered, even if he happens to be a great mind. Only when great minds surrender unto the lotus feet of Vāsudeva and know fully that Vāsudeva is the cause of all causes, as confirmed in the Bhagavad-gītā (7.19), can they become mahātmās, or the truly broad-minded. But such broad-minded mahātmās are rarely seen. Only they, however, can understand that the Supreme Lord, the absolute Personality of Godhead, is the primeval cause of all creations. He is the ultimate (parama) truth because all other truths are dependent on Him. And because He is the source of everyone's knowledge, He is omniscient; there is no illusion for Him, as there is for the relative knower.
Some Māyāvādī scholars argue that Śrīmad-Bhāgavatam was not compiled by Śrīla Vyāsadeva, and some suggest that the book is a modern creation written by someone named Vopadeva. In order to refute this meaningless argument, Śrīla Śrīdhara Svāmī points out that many of the oldest Purāṇas make reference to Śrīmad-Bhāgavatam.
