Devotee: "Arjuna was neither a great scholar nor a Vedantist, but a great soldier. A soldier is not supposed to be scholarly, and so Arjuna was selected to understand the Bhagavad-gītā because of one qualification only: he was a devotee of the Lord. This indicates that the Bhagavad-gītā is especially meant for the devotee of the Lord."
Prabhupāda: So this point is described that just like this yogi Maharishi, he has also written one Bhagavad-gītā. And what right he has got? He has no right to say anything about Bhagavad-gītā because he is not a devotee. Bhagavad-gītā is taught to Arjuna. He was neither a yogi nor a scholar nor a Vedantist nor a brāhmaṇa even. He was kṣatriya. Nor a sannyāsī even. He was gṛhastha. He had three wives and so many children. And he was fighting for kingdom. What is the qualification that Bhagavad-gītā was taught to him? Because he was devotee. People have to see how Bhagavad-gītā is to be accepted. Specially Kṛṣṇa mentions in the Fourth Chapter that "I am speaking to you. The disciplic succession is now broken.
