Uttarakhand has long been called Devbhumi ("Land of the Gods”) as the state has some of the holiest Hindu shrines, and for more than a thousand years, pilgrims have been visiting the region in the hopes of salvation and purification from sin. Gangotri and Yamunotri, the sources of the Ganges and Yamuna, dedicated to Ganga and Yamuna respectively, fall in the upper reaches of the state and together with Badrinath (dedicated to Vishnu) and Kedarnath (dedicated to Shiva) form the Chota Char Dham, one of Hinduism's most spiritual and auspicious pilgrimage circuits. Haridwar, meaning "Gateway to the God", is a prime Hindu destination. Haridwar hosts the Kumbha Mela every twelve years, in which millions of pilgrims take part from all parts of India and the world. Rishikesh near Haridwar is known as the preeminent yoga Centre of India. The state has an abundance of temples and shrines, many dedicated to local deities or manifestations of Shiva and Durga, references too many of which can be found in Hindu scriptures and legends.
