Ritual purification is a feature of many religions. The aim of these rituals is to remove specifically defined uncleanliness prior to a particular type of activity, and especially prior to the worship of a deity. This ritual uncleanliness is not identical with ordinary physical impurity, such as dirt stains; nevertheless, body fluids are generally considered ritually unclean.
Most of these rituals existed long before the germ theory of disease, and figure prominently from the earliest known religious systems of the Ancient Near East. Some writers remark that similarities between cleansing actions, engaged in by obsessive compulsive disorder sufferers and those of religious purification rites, point to an ultimate origin of the rituals in the personal grooming behaviour of the primates, but others connect the rituals to primitive taboos.
Some have seen benefits of these practices that as a point of health and preventing infections especially in areas where humans come in close contact with each other. While these practices came before the idea of the germ theory was public in areas that use daily cleaning, the destruction of infectious agents seems to be dramatic.
Varanasi (Hindustani pronunciation: [ʋaːˈraːɳəsi] ( listen)), also Benares, Banaras (Banāras [bəˈnaːrəs] ( listen)) or Kashi (Kāśī [ˈkaːʃi] ( listen)), is a city on the banks of the Ganges in Uttar Pradesh, 320 kilometres (200 mi) southeast of the state capital, Lucknow. It is holiest of the seven sacred cities (Sapta Puri) in Hinduism and Jainism. Hindus believe that death at Varanasi brings salvation. It is one of the oldest continuously inhabited cities in the world and the oldest in India.
Many of its temples were plundered and destroyed by Mohammad Ghauri in the 12th century. The temples and religious institutions in the city now are of 18th century vintage.
The Kashi Naresh (Maharaja of Kashi) is the chief cultural patron of Varanasi, and an essential part of all religious celebrations. The culture of Varanasi is closely associated with the Ganges. The city has been a cultural center of North India for several thousand years, and has a history that is older than most of the major world religions. The Benares Gharana form of Hindustani classical music developed in Varanasi, and many prominent Indian philosophers, poets, writers, and musicians live or have lived in Varanasi. Gautama Buddha gave his first sermon at Sarnath located near Varanasi.
