According to legend it was on this day that the Yamuna River and her brother Yama were re-united after a long period of separation. Yama Raja (Dharam Raja) and Yamuna (Children of God Surya) are worshiped on this auspicious day. It was on this day the Yama raja visited his sister Yamuna of Gokul. The brother, who after bath in Yamuna or some other sacred river, visits her sister, no longer gets terror stricken by the thought of Yama Raja, the God of death.
