Devotee: "Arjuna accepted Kṛṣṇa as pure, free from all material contamination, as the supreme enjoyer, as the foremost person, the Supreme Personality of Godhead, never born, the greatest. Now one may say that..., one may say that since Kṛṣṇa and Arjuna were friends, Arjuna was only saying these things to his friend. But Arjuna mentions that Kṛṣṇa is accepted as the Supreme Personality of Godhead not only by himself but by Nārada, Vyāsa and numerous other great persons."
Prabhupāda: Authorities. He accepted Kṛṣṇa as the Supreme Personality of Godhead not because Kṛṣṇa happened to be his intimate friend but on the authorities of others. And on the statement of Kṛṣṇa, and by understanding Him fully. He, he did not accept Him blindly. So this is the process of understanding Bhagavad-gītā. And although he understood fully, because in future so many rascals will come and proclaim himself that "I am also incarnation of Godhead," therefore in the Eleventh Chapter Arjuna requested Kṛṣṇa that "If you think, You can show me Your universal form," so that in future others will accept some bogus rascal as the Supreme Personality of Godhead, he may test by seeing the, I mean to say, universal form of the person. So who can exhibit this universal form except Kṛṣṇa?
So we have explained this Bhagavad-gītā in the paramparā system as we have heard from authoritative sources. So it may be a new contribution to your country, because in every edition they have concocted some ideas about Bhagavad-gītā, but we are presenting Bhagavad-gītā as it is. That's all.
