SB 1.1.7
yani veda-vidam srestho
bhagavan badarayanah
anye ca munayah suta
paravara-vido viduh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Being the eldest learned Vedantist, O Suta Gosvami, you are acquainted with the knowledge of Vyasadeva, who is the incarnation of Godhead, and you also know other sages who are fully versed in all kinds of physical and metaphysical knowledge.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srimad-Bhagavatam is a natural commentation on the Brahma-sutra, or the Badarayani Vedanta-sutras. It is called natural because Vyasadeva is author of both the Vedanta-sutras and Srimad-Bhagavatam, or the essence of all Vedic literatures. Besides Vyasadeva, there are other sages who are the authors of six different philosophical systems, namely Gautama, Kanada, Kapila, Patañjali, Jaimini and Astavakra. Theism is explained completely in the Vedanta-sutra, whereas in other systems of philosophical speculations, practically no mention is given to the ultimate cause of all causes. One can sit on the vyasasana only after being conversant in all systems of philosophy so that one can present fully the theistic views of the Bhagavatam in defiance of all other systems. Srila Suta Gosvami was the proper teacher, and therefore the sages at Naimisaranya elevated him to the vyasasana. Srila Vyasadeva is designated herein as the Personality of Godhead because he is the authorized empowered incarnation.
