Satya Yuga

The Satya Yuga (Devanagari: सत्य युग), also called Sat Yuga, Krta Yuga and Krita Yuga in Hinduism, is the "Yuga (Age or Era) of Truth", when mankind is governed by gods, and every manifestation or work is close to the purest ideal and mankind will allow intrinsic goodness to rule supreme. It is sometimes referred to as the "Golden Age." The average lifespan in the satya yuga is 100,000 years. The goddess Dharma(depicted in the form of cow), which symbolises morality, stood on all four legs during this period. Later in the Treta Yuga it would become three, and two in the later Dvapara Yuga. Currently, in the immoral age of Kali, it stands on one leg.
