Dvapara Yuga
The Dvapara Yuga is the third out of four yugas, or ages, described in the scriptures of Hinduism. This yuga comes between Treta Yuga and Kali Yuga. According to the Puranas, this yuga ended at the moment when Krishna returned to his eternal abode of Vaikuntha. According to the Bhagavata Purana, the Dvapara Yuga lasts 864,000 years.
There are only two pillars of religion during the Dvapara Yuga: compassion and truthfulness. Vishnu assumes the colour yellow and the Vedas are categorized into four parts: Rig Veda, Sama Veda, Yajur Veda and Atharva Veda. During these times, the Brahmins are knowledgeable of two or three of these but rarely have studied all the four Vedas thoroughly. Accordingly, because of this categorization, different actions and activities come into existence.
The roles of the classes
All people in the Dvapara Yuga are desirous of achievement of the scriptural dharma that is prescribed to each class, valiant, courageous and competitive by nature and are engaged only in penance and charity. They are kingly and pleasure-seeking. In this era, the divine intellect ceases to exist, and it is therefore seldom that anyone is wholly truthful. As a result of this life of deceit, people are plagued by ailments, diseases and various types of desires. After suffering from these ailments, people realize their misdeeds and perform penance. Some also organize Yagya for material benefits as well as for divinity.
