Translation: O son of Pritha, O conqueror of wealth, have you heard this with an attentive mind? And are your ignorance and illusions now dispelled?
Explanation: Krishna now inquires if Arjuna has understood and realized the meaning of this scripture. The intention of this question is that if Arjuna still has doubts, then Krishna is prepared to teach again. Srila Prabhupada explains, "The Lord was acting as the spiritual master of Arjuna. Therefore it was His duty to inquire from Arjuna whether he understood the whole Bhagavad-gita in its proper perspective. If not, the Lord was ready to re-explain any point, or the whole Bhagavad-gita if so required.
