Mount Kailash is a pyramid of black rock and white snow, 6,638 metres high, standing alone on the western Tibetan plateau in the Ngari prefecture of China, sacred to Hindus, Buddhists, Jains and the Bon religion, never climbed, with four of the great rivers of Asia, the Indus, the Sutlej, the Brahmaputra and the Karnali, rising around its base, and it is circled on foot by pilgrims in a walk of 52 kilometres over a pass of 5,630 metres. The kora, the circuit, takes three days for most walkers and one day for the Tibetans who do it in a single push, and a single round is said to erase the sins of a lifetime; the path leaves from Darchen and on the first day ends at Drira Phug, the cave of the female yak horn, where the north face stands straight up behind the roofs, the place from which the mountain is photographed above all. On the south face a vertical cleft crossed by horizontal layers of rock forms what looks like a giant natural swastika, an ancient symbol of good fortune across the Asian faiths, and Hindus hold the summit to be the home of Shiva, and Buddhist tradition says the yogi Milarepa won the mountain for Buddhism by racing a Bon priest to its summit at sunrise.
The second day is the pass. An hour below the prayer flags of the Drolma La the path reaches Shiva Tsal, a stony flat heaped with abandoned coats, shoes and cut hair, where the pilgrim leaves a piece of the old self and passes through a symbolic death, and twice the circuit runs up against a Dikpa-karnak, a boulder with a gap that tests sin; some pilgrims measure the whole circuit with their bodies, prostrating full length and stepping to where their hands reached, a round of three weeks. Lake Manasarovar below has its own four-day circuit, and September and October are the clearest months. Kailash is the mountain that no one has climbed, and everyone walks around it.
