Dvapara Yuga

Dvapara Yuga (Devanagari: द्वापर युग) is the third out of four yugas, or ages, in the religion of Hinduism. This yuga comes after Treta Yuga and is followed by Kali Yuga. According to the Puranas this yuga ended at the moment when Krishna returned to his eternal abode of Vaikuntha.There are only two pillars left of religion in the Dvapara Yuga. Bhagwan Vishnu assumes the color yellow and the Vedas are categorized into four parts that is Rig, Sama, Yajur and Atharva. During these times the Brahmins are knowledgeable of two, sometimes three Vedas, but rarely have studied all the four Vedas thoroughly. Accordingly, because of this categorization, different actions and activities come into existence.

Dvapara Yuga (Sanskrit) [from dvapara twain, double + yuga age] The third of the four great yugas which constitute a mahayuga (great age). Its duration is 864,000 human years. The Mahabharata gives a description of the dvapara yuga:
"In the Dwapara Yuga righteousness was diminished by a half. The Veda became fourfold. Some men studied four Vedas, other three, others two, others one, and some none at all. Ceremonies were celebrated in a great variety of ways. From the decline of goodness only few men adhered to truth. When men had fallen away from goodness, many diseases, desires, and calamities, caused by destiny, assailed them, by which they were severely afflicted and driven to practise austerities. Others desiring heavenly bliss offered sacrifices. Thus men declined through unrighteousness" (abridged by Muir, 1:144) Bronze Age. See HESIOD, AGES OF; DVAPARA YUGA
