“‘The meaning of the Vedānta-sūtra is present in Śrīmad-Bhāgavatam. The full purport of the Mahābhārata is also there. The commentary of the Brahma-gāyatrī is also there and fully expanded with all Vedic knowledge. Śrīmad-Bhāgavatam is the supreme Purāṇa, and it was compiled by the Supreme Personality of Godhead in His incarnation as Vyāsadeva. There are twelve cantos, 335 chapters and eighteen thousand verses.’
