The Treta Yuga, in Hinduism, is the second and second best of the four yugas (world ages) in a Yuga Cycle, preceded by Krita (Satya) Yuga and followed by Dvapara Yuga
Treta Yuga lasts for 1,296,000 years (3,600 divine years)
Treta means ‘a collection of three things’ in Sanskrit, and is so called because during the Treta Yuga, there were three Avatars of Vishnu that were seen, the fifth, sixth and seventh incarnations as Vamana, Parashurama and Rama, respectively
The bull of Dharma symbolizes that morality stood on three legs during this period
It had all four legs in the Satya Yuga and two in the succeeding Dvapara Yuga
Currently, in the immoral age of Kali, it stands on one leg
