Su-medhasaḥ. Kṛṣṇa-varṇaṁ tviṣākṛṣṇam. Lord Kṛṣṇa, or Lord Caitanya Mahāprabhu, He's Kṛṣṇa. Tviṣākṛṣṇa: by complexion golden. Therefore, by complexion is not kṛṣṇa, or blackish, but He's Kṛṣṇa. Kṛṣṇa has four colors. That is in the śāstra: śuklo raktas tathā pīta idānīṁ kṛṣṇatāṁ gataḥ (CB Ādi-khaṇḍa 14.136). So one of the colors of Kṛṣṇa is yellow, golden. That is Caitanya Mahāprabhu. So kṛṣṇa-varṇaṁ tviṣākṛṣṇaṁ sāṅgopāṅgāstra-pārṣadam (SB 11.5.32), that Lord Kṛṣṇa now, in the form of Lord Caitanya, Śrī Kṛṣṇa Caitanya, and sāṅgopāṅgāstra-pārṣadam, associated with His personal expansion, śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda . . . this is described. Sāṅgopāṅgāstra-pārṣadam, with these . . . in the former incarnation, He was killing the demons directly with sword or the sudarśana-cakra, some way or other. Now, in this age, they're already dead. So if Kṛṣṇa comes to kill them with sudarśana-cakra and sword, they will not be profited. Therefore, these are the astras, these are the swords: the devotees of Lord Kṛṣṇa who was preaching Kṛṣṇa consciousness. They are the Lord's weapon. And they're getting victory. Sāṅgopāṅgāstra-pārṣadam. So those who are intelligent, su-medhasaḥ, they will worship this form of God in this Kali-yuga. And what is the process of worshiping? Yajñaiḥ saṅkīrtana-prāyaiḥ.
So these rascal, position, the rascal guardians, you have to fight with them, but not with sword or any other weapon: the saṅkīrtana movement, yajñaiḥ saṅkīrtana-prāyaiḥ. If you stick to this principle of chanting Hare Kṛṣṇa mantra, yajñaiḥ, if you have got good brain, su-medhasaḥ, then you will take this means, and by the help of Śrī Kṛṣṇa Caitanya Mahāprabhu you'll conquer all over the world. All over the world. You cannot take up any other means. That will not be successful, because the śāstra says, yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ (SB 11.5.32). So at the present moment, our position is very precarious. We are in the darkness, the ignorance, and so many other things, corollaries to these things. Rāṣṭrāṇi vā tair avaropitāni itas tataḥ. Just see. Five thousand years ago this Śrīmad-Bhāgavatam was written, the symptoms of Kali-yuga. Now you see that itas tato vāśana-pāna-vāsaḥ-snāna. Now everywhere, all over the world, the young boys and girls, they have no fixture where they'll live, where they'll take their bath, where they'll eat or how . . . or how they have sex. No. These are preliminary necessities of life. One must have a good place to live. One must have sufficient nice foodstuff to eat. Sleep. Eating, sleeping, mating—this is physical necessities. So in the Vedic civilization, these necessities are prescribed in a regulated way so that he can satisfy his physical necessities, at the same time, become Kṛṣṇa conscious and go back to home, back to Godhead.
