One sees the advent of religious sacrifices i.e. Yagyas in the Treta yuga. One pillar of the four pillars of religion meets its end. The colour of Bhagwan Achyut becomes red. People in this era will be truthful and would perform all the religious ceremonies according to the sacrifices. It is the Treta yuga where one can see the overtures of Yagyas, religion and allied activities. People would beget desired fruits by performing actions, donations mentioned in the Vedas and by taking resolutions.

All people in this era were assiduous and active. The main religion of Brahmins was truth that is truthful speech, good conduct and love towards all creatures. The common religion of all the Brahmins was Yagya, self-study and donation. The primary aim of Shudras was service towards Brahmins, Kshatriyas and Vaishyas. The duties of Kshatriyas and Vaishyas were the protection of people and agriculture, trade and poultry respectively. All people would sincerely adhere to their respective duties and as a result they would be blessed with celestial bliss.

The average life expectancy of a human in the Treta yuga was approximately 3000 years. All the Kshatriyas born in this era were valiant, zealous, big thinkers, pious, truthful, beautiful, suitable to be blessed, revered and the protectors of all people. The Vedas, religious sacrifices and Varnashram were adhered to very strictly in the Satyayuga and the Treta yuga.
