So He wanted to establish that for right cause there must be fighting. You cannot abolish violence from the world. This is the instruction of Kṛṣṇa in Bhagavad-gītā. If required, violence will be taken. And Kṛṣṇa induced Arjuna to be violent. Arjuna wanted to be nonviolent, but He wanted that "You should. You must fight. This fight is arranged by Me." So these examples.
These are the examples. Nothing is bad... Nothing is good if it is not purposeful. That is the whole purpose of teaching Bhagavad-gītā. Nothing is good; nothing is bad. Everything is good, everything is bad, in this material world, but we have to see. Just like the common phrase goes, "The end justifies the means. The end justifies the means." So that is Kṛṣṇa teaching here that He has nothing to gain. He is full in Himself. But just to set examples in the world He was taking part in the fighting because He wanted to establish it that fighting for good cause should not be avoided. That was His mission.
Then further He says,
- yadi hy ahaṁ na varteyaṁ
- jātu karmaṇy atandritaḥ
- mama vartmānuvartante
- manuṣyāḥ pārtha sarvaśaḥ
- (BG 3.23)
Manuṣyāḥ. Now just see. Here it is said. Manuṣyāḥ means all men. All men. So Kṛṣṇa is not for a particular society or particular religious community or particular country or particular time. No. Kṛṣṇa is the leader of all men for all the time in all the countries in all the worlds and all the universes. So He is not a sectarian Personality of Godhead. We should know. Manuṣyāḥ. Manuṣyāḥ, it is plural number: "All men." All men. So He said, "If I do not set example by My practical work, then because I am the leader of all men, all living entities, they will be wrongly directed." Wrongly directed.
