Millions of Hindus take holy bath in Yamuna River, especially during auspicious days. A visit to Yamunotri Temple in Himalayas is also considered highly meritorious. A popular legend states that taking holy bath, or dip, in Yamuna will help in a painless death. This is because Yamuna is believed to be the sister of Yama, the Hindu God of death. Another legend states that Yamuna is the daughter of Surya Bhagava, the Hindu Sun God. Yamuna River originates from a pond named Saptarishi Kund at an altitude of 4421 meter in the Kalinand Mountain. Yamuna River travels for nearly 800 km before merging with Ganga at Prayag in Allahabad. Yamuntori Temple is part of the famous Char Dham Yatra in the Himalayas. In a year due to harsh winter, the temple remains open only from middle May to November beginning.
