Over and above this, Śrīmad-Bhāgavatam is the personal commentary on the Vedānta-sūtra by Vyāsadeva after he had attained maturity in spiritual realization. He was able to write it by the mercy of Nārada. Śrīla Vyāsadeva is an incarnation of Nārāyaṇa, the Personality of Godhead; therefore there is no question about his authority. Although he is the author of all Vedic literature, he specifically recommends the study of Śrīmad-Bhāgavatam above all other books.
