What is that līlā, līlā pastime? When God wants to have some desire to fulfill that, "I, I, I should fight . . ." Sometimes you sometimes feel mock fighting with friends or with your children. Similarly, wherefrom this desire comes unless the desire is in God? Because He is the origin of all, everything. So don't you feel sometimes, mock fighting? That is enjoyment, fighting with friends, boxing. That is not fighting; that is enjoyment. Similarly, God wants to enjoy by fighting.
So Vaikuṇṭha, there is no fighting, because nobody can be found there enemy. Everyone is obedient servant. Therefore He comes here to find out some enemy. The two functions are served. Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8).
He satisfies His fighting spirit—at the same time, He protects the devotees and protects that enemy also by killing him. Because when a, when a demon is killed by the by the Supreme Lord, he is at once liberated. The liberation which he had to achieve after many, many births, he at once achieves. That is the advantage. So He saves the enemy and saves the devotee, in a stance . . . at the same times, He satisfies His fighting desire.
So God is good. So any fight, that is also good. It is not that Kṛṣṇa is inducing, inciting Arjuna, "Fight." There is a plan, big plan. So foolish people who criticize, "Oh, Kṛṣṇa is inciting war. We are very good men, nonviolence." So this "good man" has no value. That fighting has much value. But there is a plan, good plan. So this is called pastime, līlā, līlāvatāra.
So what are the līlāvatāra? Lord Caitanya says, līlāvatāra kṛṣṇera nā yāya kathan (CC Madhya 20.297): "How many number of līlāvatāras are there, nobody can count." God is unlimited, so anything manifested by Him is unlimited. That cannot be calculated by us.
