Hiraṇyakaśipu wants to hurt Kṛṣṇa. What he can do to Kṛṣṇa? So where is the cause of anger? He was angry not that Hiraṇyakaśipu was a demon or non-devotee; He was angry because that demon was teasing the devotee. For His personal account, He cannot be angry. What anyone can harm Kṛṣṇa? He is so powerful.
Suppose a small ant comes and bites me. So is that the cause of my anger? No. What is that? That is nothing. Similarly, what Hiraṇyakaśipu can do so that the Lord should be angry? But then why then He was angry? He was angry for His devotee.
Similarly, we also, if we are devotee, we shall be angry when God is insulted. When devotee is insulted, we should be very much angry. But if somebody insults me, I don't be angry. "All right, he insulted. I tolerate." But when you speak against God, when you say: "I am God," I shall beat you with shoes, I shall be so much angry. You see? That should be attitude of the devotee.
As God is angry for his devotee, similarly, our anger should be also utilized for God. Just try to understand. It is not that we shall not be angry. Yes, we shall be angry, but in suitable place, where God is insulted. When a rascal is claiming that he is God and deceiving others, you must be very much angry, "You rascal, what you are doing?" Somebody may say: "Oh, you are devotee? Why you have become so angry?" Now, why not? Here is the question of God and His devotee.
Just like Caitanya Mahāprabhu taught us that, "You become tolerant than the tree and humble than the grass." But when Jagāi-Mādhāi insulted Lord Nityānanda, oh, He immediately became so angry, "Oh, bring My cakra. I shall kill these persons." Did He become a tolerant like the tree, "All right, Nityānanda is insulted. Let Me become tolerant"? (laughs) No, no.
