So saṅga upaṅgāstra-pārṣadam. Astra, astra means weapon. So saṅga . . . Because when God incarnates, He has got two business: paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8). So one business is to give protection to the devotee and to annihilate the duṣkṛta, those who are sinful. So for annihilating, it requires weapon, śaṇkha, cakra, gadā, padma. Lord Rāmacandra has got bows and arrows, and Kṛṣṇa has got Sudarśana-cakra. But here it is said, saṅga-upaṅga-astra. What is that astra, weapon? Caitanya Mahāprabhu has no astra. Seemingly there's no . . . But this is astra, this hari-saṅkīrtana. This is astra. In the Kali-yuga there is no profit by killing them. They're already killed. So therefore this is the astra. To kill the miscreants this is astra, this hari-saṅkīrtana. If they simply chant Hare Kṛṣṇa, this is astra that will kill all their sinful reaction of life; they'll become devotee. This is astra. Now it is not required the bows and arrows or . . . Because they're already dead, because they have no conception of God. Simply fighting how to avoid God, this is their business. It is very difficult to convince them about the existence of . . . They're seeing every moment there is existence of God, but they're so stubborn, so much bewildered by māyā, they'll not. So under the circumstances Caitanya Mahāprabhu, He's therefore called namo mahā-vadānyāya, most munificent incarnation. Why? Kṛṣṇa-prema-pradāya te (CC Madhya 19.53). Even without understanding Kṛṣṇa, simply by chanting Hare Kṛṣṇa mantra they become ecstatic for love of Kṛṣṇa. This is Caitanya Mahāprabhu's benediction: no qualification, but if he simply chants Hare Kṛṣṇa mantra he'll be ecstatic. Kṛṣṇa-prema-pradāya te.
To understand Kṛṣṇa is very difficult job. Manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye (BG 7.3). Out of many millions of persons, one is endeavoring to make his life perfect. But they do not know what is perfection of life. So yatatām api siddhānām. Siddhi means to understand that "I'm not this body. I don't belong to this material world." That is siddhi. Siddhi. Everyone is under the impression that "I'm this body." "I am Indian," "I am American," "I am Hindu," "I am Muslim," "I am Christian"—bodily upādhi, designation. He does not become free from the designation. The other day we were talking on Mr. Huxley, I think. He was talking of philosophy, but he was thinking, "I'm Englishman. I do this like that." So this, that bodily concept of life is there, although he's philosopher. What kind of philosophy? Philosophy begins when there is no more bodily conception. That is here. Sarvopādhi-vinirmuktaṁ tat paratvena nirmalam (CC Madhya 19.170). So this kind of philosophy has no meaning, because how a dog can become philosopher? That is not possible. A human being can become philosopher. But the, so long I'm in the bodily concept of life, I'm in the line of cats and dogs. So how we can become philosopher? There is no question of philosopher. But they're philosophizing, means bluffing, and similar men, he's thinking, "I believe." You believe or not believe, the law will go on.
So everyone is proposing "I believe." That's why the government law is there, that "If you do this, you'll be punished like this." That is government law. Suppose you have stolen something, committed theft. You must be punished by six months' imprisonment. So you believe or not believe, the law will act. If you say in the court, "I believe," what is the meaning of your belief? There is no question of belief. Law is law. Ignorance is no excuse. If you go in the court and if you are punished, so if you say, "My Lordship, I believe like this. I'll not be punished. So you're punishing me," so that is no excuse. You believe or not believe, the law is law. So, similarly, these philosophers theorizing so many "I believe." So these things will not do. These things will not do. That is useless, simply waste of time. You must know there is God. How we can deny it? There is supreme power. I am being controlled every moment. Who wants to die? And who is forcing me to die? How we can deny the superior power? I do not want to become old man, and superior power forces me, "You must become old man." So, so long there is force behind you, you have to act according to that. Where is your so-called belief or independence? That is foolishness. That is foolishness. But they have no brain that "I am being kicked. I'm being enforced to do something, and still I'm thinking 'independent,' 'I believe.' " What is this meaning of your belief? There is no question of. This is foolishness.
