So this is preaching. This is preaching. So Arjuna has to be a preacher. Practical preacher. What is that preaching? That he has to sacrifice everything for Kṛṣṇa's sake. That's all. This is preaching. Sakalam eva vihāya dūrāt. Arjuna will be the greatest example, how he became Kṛṣṇa conscious, in the last Tenth Chapter. He will say, sarvam etad ṛtaṁ manye yad vadasi keśava: (BG 10.14) "My dear Kṛṣṇa, Keśava, whatever you say, I accept in total." Without any interpretation, or "This is like this, this is like that, this is not very good." Ardha-kukkuṭī-nyāya (Cc. Ādi-līlā 5.176). All rascals, they accept this Bhagavad-gītā on the principle of ardha-kukkuṭī-nyāya. In the nyāya, in the logic. There is a logic, ardha-kukkuṭī-nyāya.
