So Caitanya Mahāprabhu, tviṣā akṛṣṇam. He is not blackish. Then He must be other form, śukla, rakta, or pīta. So He assumed the pīta, yellowish color. Therefore tviṣā akṛṣṇam. Tviṣā means by complexion. So kṛṣṇa-varṇam, kṛṣṇaṁ varṇayati, iti kṛṣṇa-varṇam, or kṛṣṇa iti kṛṣṇa-varṇam, and tviṣā, by complexion, akṛṣṇa, pīta, idānīṁ pīta-varṇam. Pīta-varṇa gaura, golden avatāra. And sāṅgopāṅgāstra-pārṣadam. He is always surrounded by associates, specially by Śrī Advaita, Gadādhara, Śrīvāsādi. Śrī Kṛṣṇa Caitanya, He is Kṛṣṇa, then Nityānanda, then Advaita, then Gadādhara, then Śrīvāsa, and many other devotees always followed. That is the life of Śrī Caitanya Mahāprabhu. Wherever He went, many followers chanting Hare Kṛṣṇa, plus these principal associates were with Him. Therefore sāṅgopāṅgāstra-pārṣa... And these sāṅga upāṅga were His astra. Astra, astra means weapon.
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 sādhūnām. Another: vināśāya ca duṣkṛtām, to annihilate the demons. So there..., for annihilating, for killing, you require weapon. Kṛṣṇa has His weapon, sudarśana-cakra. Lord Rāmacandra has His weapon, bow and arrow. What is the weapon of Śrī Caitanya Mahāprabhu? 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) So 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 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, Śrīvāsādi 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.
