Nobody can be equal with God. Even such great demigods like Śiva and Brahmā... They are considered to be the highest demigods. Still, in the scriptures it is said that nobody should place all these demigods, even Śiva and Brahmā, on equal footing with Viṣṇu, Viṣṇu the Supreme Personality of Godhead, or Kṛṣṇa. So Kṛṣṇa has nothing to do. God, who is actually God, He has nothing to do. He has nothing to do. He is God from the very beginning. And He is all-powerful with all opulences. That is the God. So Kṛṣṇa says, "I have nothing to do," triṣu lokeṣu kiñcana, "not only in this earth, but in the three worlds, anywhere, anywhere I can go, anywhere I can work, anywhere I can see. But still, I have nothing to do."
Na anavāptam avāptavyam: "It is not that I am deficient in My possession." We work because we find deficient ourself. In any power, in any, either spiritual power or material power, we have to work because we are deficient. So Kṛṣṇa is not deficient so that He has to fill up the deficiency. No. Na anavāptam. So still, varta eva ca karmaṇi. Now, He says that "Arjuna, you see that still, I have engaged Myself in the worldly duties." Why? Just to become the ideal man. Although He was not man, He was God, because He was playing the part of a man, therefore He was...
Why He was taking part in the battlefield? He had nothing to gain out of it personally, but why He was taking part in the battlefield? Just for the right cause. 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.
