All Rishis as well as Devarshi Narada, Asita, Devala and Vyasa speak of You in the same manner. You also state that this is so.
Arjuna cites an assortment of Sages who hold Krishna in high esteem. First is Narada, given to meandering the world over, reporting tirelessly whatever worthy and consequential he witnesses. Vyasa has superb distinction. Soon after his birth, he was abandoned by Satyavati and Sage Parashara. None knows how he grew up as a child thereafter.
However, he appears as the illustrious ascetic Seer, authoring many Puranas, editing Vedas and composing Brahmasutras, Mahabharata and Srimad Bhagavatam. None can measure the Sage’s knowledge and austere majesty, not to speak of matching it.
All these Saints esteem Krishna greatly. Arjuna adds that Krishna himself has divulged explicitly his own grandeur. There is thus an amalgam of Krishna’s own words as well as those of other renounced Seers and Sages about Krishna’s unique place of greatness.
