Lord Caitanya spreads Kṛṣṇa consciousness through chanting, requiring only commitment, not expensive rituals or ceremonies.Listen — Srila Prabhupada Uvaca
Prabhupāda: So we have discussed the different names of Manu, the father of man. In different millenniums there are different Manus, and the present Manu is Vaivasvata Manu. Out of the fourteen Manus, now it is, the eighth Manu is going on at the present moment. That means this is about one o'clock in the day of Brahmā, just past noon.
It is going to be afternoon. And during Brahmā's sleeping time all these planets will be, I mean to say, not annihilated, but inundated, you see—devastation with water. So after the finishing of these fourteen Manus here will be evening, night, and there will be devastation, and half of this universe, up to the sun planet, or above that, everything will be covered with water. Instead of air, there will be water. Then again there will be again...
This is kaṇòa-pralaya. And mahā-pralaya means when Brahmā dies, then everything is finished. So these fourteen Manus we have mentioned yesterday. Now yugāvatāra. Yugāvatāra means just like there are four yugas: Satya, Tretā, Dvāpara, Kali.
The ages of each yuga we have mentioned already. Now in the Satya-yuga, when the yugāvatāra comes, He is white. He is Hayagrīva in the Satya-yuga, as white as our Hayagrīva brahmacārī. Yes.
He is white. And rakta. Śukla-rakta-kṛṣṇa-pīta-krame cāri varṇa [Cc Madhya 20.330]. [In the four yugas—Satya, Tretā, Dvāpara and Kali—the Lord incarnates in four colors: white, red, black and yellow respectively. These are the colors of the incarnations in different millenniums.] In the Satya-yuga when the incarnation of yugāvatāra comes, His complexion is white.
And in the next yuga, Tretā-yuga, the complexion is red. And the next yuga, Dvāpara-yuga, the complexion is black, kṛṣṇa. And the next, Kali-yuga, the complexion is yellow. Lord Caitanya is yellow. kṛṣṇa-varṇaṃ tviṣākṛṣṇaṃ sāìgopāìgāstra-pārṣadam yajñaiḥ saìkīrtana-prāyair yajanti hi su-medhasaḥ [SB 11.5.32] [In the Age of Kali, intelligent persons perform congregational chanting to worship the incarnation of Godhead who constantly sings the names of Kṛṣṇa. Although His complexion is not blackish, He is Kṛṣṇa Himself. He is accompanied by His associates, servants, weapons and confidential companions.] In this age, Kali-yuga, this is the yugāvatāra, Lord Caitanya. And His description is mentioned in Śrīmad-Bhāgavatam. Five thousand years before, it was mentioned that kṛṣṇa-varṇam.
Kṛṣṇa-varṇam means that He is in the category of Kṛṣṇa. Svayaṃ-kṛṣṇa. You can take the meaning of kṛṣṇa-varṇam like this. Varṇa means a caste, or classification.
