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.
