The great Hindu city of Varanasi, also known as Banaras or Benares, stretches along the River Ganges, its waterfront dominated by long flights of stone ghats where thousands of pilgrims and residents come for their daily ritual ablutions. Known to the devout as Kashi, the Luminous – the City of Light, founded by Shiva – Varanasi is one of the oldest living cities in the world. It has maintained its religious life since the sixth century BC in one continuous tradition, in part by remaining outside the mainstream of political activity and historical development of the Subcontinent, and stands at the centre of the Hindu universe, the focus of a religious geography that reaches from the Himalayan cave of Amarnath in Kashmir to India’s southern tip at Kanyakumari, Puri to the east, and Dwarka to the west. Located next to a ford on an ancient trade route, Varanasi is among the holiest of all tirthas – “crossing places”, that allow the devotee access to the divine and enable gods and goddesses to come down to earth. It has attracted pilgrims, seekers, sannyasins and students of the Vedas throughout its history, including sages such as Buddha, Mahavira (founder of the Jain faith) and the great Hindu reformer Shankara.
