"O Kṛṣṇa, I totally accept as truth all that You have told me." That's all. That is understanding. Arjuna is not a fool. He said, "Whatever You have said, I accept them as truth." That is real understanding.
Evening Darsana -- July 11, 1976, New York:
Hari-śauri: "O Kṛṣṇa, I totally accept as truth all that You have told me."
Prabhupāda: That's all. That is understanding. Arjuna is not a fool. He said, "Whatever You have said, I accept them as truth." That is real understanding. But as soon as you make amendment, then you have not understood Kṛṣṇa. Sarvam etad ṛtaṁ manye yan māṁ vadasi keśava [Bg. 10.14]. There are so many rascals, they think "I don't believe in this, I don't believe in this." That is not understanding of Bhagavad-gītā.
Indian man (3): Does it mean that before we, or anybody, before he at all...
Prabhupāda: Before he, if... First of all he must know what is Kṛṣṇa. Then he will understand that what is Kṛṣṇa. That he will understand from Bhagavad-gītā by this beginning. And at the end Kṛṣṇa is accepted as the Supreme Lord. So if you know that Kṛṣṇa is Supreme Lord, then whatever He says is correct.
Indian man (3): That means the first thing is to accept Kṛṣṇa as God, and then...
Prabhupāda: Not blindly.
Indian man (3): Not blindly.
Prabhupāda: Not blindly. But you must know... Just like if you accept the government, and the government orders, "This man should be hanged," you have to accept it. You cannot protest that "The government has ordered this man should be hanged. It should be protested." And who will care for your protest? Government is government. You cannot criticize. You may criticize on account of your less intelligence, but government order is all. Is it not? If government orders that "This man should be hanged," can you say anything against it? It will not be accepted. Similarly, if you know that Kṛṣṇa is the Supreme Lord, then as Arjuna said, sarvam etad ṛtaṁ manye yan māṁ vadasi keśava [Bg. 10.14]. Paraṁ brahma paraṁ dhāma pavitram [Bg. 10.12]. Unless you understand Kṛṣṇa and Kṛṣṇa's personality, you will try to weight the strength of His words, the value of His words. But if you understand other statement... Just like Kṛṣṇa says mattaḥ parataraṁ nānyat kiñcid asti dhanañjaya [Bg. 7.7], "I am the supreme authority." So if He is the supreme authority, then whatever He has said, it is all right. But if you have doubt about He's supreme authority, then you will find out His fault. That is the defect.
