Treta Yuga

Overview
Treta Yuga (IAST: Tretā-yuga) (Devanagari: त्रेतायुग), 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.

68, A. 3)). On the third day the earth, the lowest body, received its form by the withdrawal of the waters, and there resulted the distinction in the lowest body, namely, of land and sea. Hence Scripture, having clearly expressed the formless state of the earth, by saying that it was "invisible" or "void," expresses the manner in which it received its form by the equally suitable words, "Let the dry land appear."
