What did he do, Kṛṣṇa, uh, Arjuna, after hearing Bhagavad-gītā? He said: "O my dear Kṛṣṇa," naṣṭo mohaḥ, "my illusion is over," tvat-prasādāt, "by Your kindness." That means, "You have so kindly instructed me. Now my illusion is over." Then? What you are going to do? Your illusion is over? Ah, kariṣye tad vacanam: "Oh, I shall act as You are advising me." That means, "I shall fight. I shall fight."
So evaṁ param . . . Arjuna understood Kṛṣṇa in this way . . . that is a fact. You'll find in the Bhagavad-gītā. Now, if you follow the principle or the footprints of Arjuna . . . that Arjuna understood Bhagavad-gītā in this way . . . now, if you follow the principles of Arjuna, then you understand Bhagavad-gītā. It is not very difficult.
That is stated, how, what he, what Arjuna understood. That is stated in the Bhagavad-gītā in the Tenth Chapter: paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (BG 10.12). He accepted that "You are Supreme Personality of Godhead. Nobody knows about Your personality." These things are described there. So you haven't got to labor very hard. If you simply follow mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). If you follow the footprints of great personalities like Arjuna, like Nārada, like Brahmā, like Śaṅkarācārya, like Rāmānujācārya, oh, they are there. Their precepts and their injunction is there. But you have to select a person, a bona fide spiritual master. You have to see that whether he's actually in that disciplic succession. And how you can test it? You'll test it that a bona fide spiritual master will instruct you the same thing as Kṛṣṇa instructed.
