Treta Yuga (Devanagari: त्रेता युग) is the second out of four  yugas, or ages of mankind, in the religion of Hinduism. Treta means third in Sanskrit. The first yuga is Satya Yuga of perfect morality and the one after Treta is the  Dvapara Yuga. The most famous events in this yuga were Lord Vishnu's fifth, sixth and seventh incarnations as Vamana, Parashurama and Rama respectively. The Dharma bull, which symbolises morality, stood on three legs during this period. It had all four in the Satya Yuga and two in the later Dvapara Yuga. Currently, in the immoral age of Kali, it stands on one leg. The Treta Yuga lasted 1,296,000 years.
