Devotee: One professor the other day was trying to convince one of our boys that you were coming in the disciplic succession and were authorized to translate all these books.
Prabhupada: Yes, that is right.
Devotee: Because he was dressed, and he didn't know that he was your disciple, so he was saying, "Bhaktivedanta Swami, he is coming in a disciplic line straight from Kṛṣṇa. That's why he can speak on all these books."
Prabhupada: Yes, that is a fact. That authority I have got. That's a fact.
yasya deve parā bhaktir
yathā deve tathā gurau
tasyaite kathitā hy arthāḥ
They become manifest, all the meanings of the Vedic literature. Yasya deve parā bhaktiḥ.
