God advents for two purposes. What are the two purposes? Paritrāṇāya sādhūnām (BG 4.8): just to give relief and deliver the devotees. The devotees are always anxious to see God, so God comes down to give relief to the devotee, being present before them. Paritrāṇāya sā . . . Another: vināśāya ca duṣkṛtām, to annihilate the demons. So there . . . For annihilating, for killing, you require weapons. Kṛṣṇa had His weapon, sudarśana-cakra. Lord Rāmacandra has His weapon, bow and arrow. What is the weapon of Śrī Caitanya Mahā . . .? Sāṅgopāṅgāstra-pārṣadam. His associates are His weapons. This is astra. Because in the Kali-yuga they are so fallen, even they are demons, they are third-class, fourth-class demons. (laughter) (laughs) They need not be killed. They are already killed. Their mode of life, their atmosphere, they are always dead. Just like we see so many demons. So what is there to kill them? They are already killed. They have no life. So this killing process in Kali-yuga is to kill their demonic propensities. And how to kill that demonic propensities? By spreading Hare Kṛṣṇa movement. This is astra. Otherwise to kill them is not . . . By life, it is not difficult. One slap is sufficient. You don't require other weapon. But real Kṛṣṇa comes to kill or to give protection—because He is Absolute, it is the same thing. If He is killing some demons, He is giving him protection. He stops his demonic activities further, to implicate himself in more trouble. Therefore when Kṛṣṇa kills one demon, that means He saves him. He saves him. The Absolute; this is Absolute. Either He give . . . Protects His devotee or kills the demon, the result is the same. Therefore He is called Absolute.
So in this age, Kali-yuga, to kill the demons means to stop their demonic activities by the astra, kīrtana, hari-saṅkīrtana, which is spread by His associates. Nityānanda Prabhu, Advaita Prabhu, Śrīvāsa ādi-gaura-bhakta-vṛnda, they are going door to door, country to country, city to city, and saving the demons from being implicated more and more in material existence. Therefore this is the astra. Astra means the killing. Real purpose . . . The living entity is eternal. How he can be killed? Na hanyate hanyamāne śarīre (BG 2.20). So to kill means to kill his demonic nature. Otherwise how he can be killed? Ya imam . . . There is a verse that anyone who knows that the living entity is never killed and . . . A living entity does not kill anyone; neither a living entity is ever killed. One who knows this, he knows. So that is the position. So killing does not mean that killing the living entity. That is not possible. Na jāyate na mriyate vā. Killing means to kill his demonic activities. Stop. Killing means stop acting.
So sāṅgopāṅgāstra-pārṣadam. This is the description of the God, Kṛṣṇa, in this age. That is Caitanya Mahāprabhu. Kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ sāṅgopāṅgāstra-pārṣadam (SB 11.5.32). And how to worship Him? What is the process? Yajñaiḥ saṅkīrtanaiḥ. That's all. You keep Caitanya Mahāprabhu's Deity and chant and dance—your life is successful. So easy. We are worshiping Rādhā-Kṛṣṇa. That is very difficult. But if we keep Caitanya Mahāprabhu with His associates, this Pañca-tattva, Gaura-Nitāi, Gaura-Gadādhara, or Pañca-tattva, and worship Him according to the śāstra description . . . The śāstra description is yajñaiḥ saṅkīrtanaiḥ. This is yajña. Life is meant for performing yajña. In the Bhagavad-gītā it is said, yajñārthe karma. You are very busy. Yes, you should be busy always, twenty-four hours. For what purpose? Yajñārthe, not for your sense gratification. That is devotional life. Yajñārthe karma. Karma. We are not dull matter. We have got our flexible hands and legs to work. People think that "These Kṛṣṇa conscious men, Hare Kṛṣṇa people, they are escaping."
