In the beginning, there is Satya-yuga; and the next, Tretā-yuga; next, Dvāpara-yuga; and this is the Kali-yuga. The aggregate of all these four yugas is called yuga: sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). The duration of Satya-yuga is 1,800,000's of years; and the next, Tretā-yuga, roughly 1,200,000's of years; and Dvāpara-yuga, 800,000's of years; and this Kali-yuga, 432,00 000's of years. So we are in this Kali-yuga. In this Kali-yuga we have passed only 5,000 years. Out of 432,000's of years we have passed only 5,000. Since the Battle of Kurukṣetra, which took place 5,000 years ago, the Kali-yuga has begun.
So this chapter is on the subject matter "How Parīkṣit Received the Age of Kali." We are studying this chapter at the present moment. In Los Angeles we were studying, and again, after that, we are presenting. So Kali-yuga is not very good age, simply faults. We have several times discussed that in this age, people's duration of life, mercifulness, bodily strength and so many things, eight kinds of things, will be reduced. The age is reducing, the bodily strength is also reducing. Now you American generation, you are not as strong as your father or grandfather. You can understand that. You are not so luxuriantly grown up, bodily growth. There are so many reasons, but this is the symptom of age of Kali. And they're described in the Śrīmad-Bhāgavatam, foretold, five thousand years ago, what will happen in this Kali-yuga. That is all explained in the Twelfth Canto of Śrīmad-Bhāgavatam, third, fourth chapter. So simply full of faults. Social life, political life, religious life—everything has been described there. And one thing I can see very practical, that in this age, lāvaṇyaṁ keśa-dhāraṇam (SB 12.2.6). It is stated there that people will think that by keeping long hairs they will become very beautiful. That is stated there. Dāmpatye ratim eva hi, husband and wife's relation will depend on the strength of sex. These are described there. Svīkāra eva udvāhe (SB 12.2.5): marriage will be performed simply by agreement.
