Mount Kailash is a pyramid of black rock and white snow standing alone on the western Tibetan plateau, and nobody has ever stood on top of it. Hindus, Buddhists, Jains and the older Bon faith all take the 6,638-metre summit for the axis of the world. The Indus, the Brahmaputra, the Karnali and the Sutlej all rise within sixty kilometres of it, and Tibetan tradition gives each an animal mouth: Lion, Horse, Peacock, Elephant. So you walk around it instead: 52 kilometres from Darchen, three days for most and a single push for Tibetans, and one round is said to clear a lifetime of wrongdoing. The first day ends at Drira Phug, the cave of the female yak horn, and the north wall stands straight up behind the roofs where you sleep. Lake Manasarovar below has a four-day circuit of its own, and pilgrims carry its water home in flasks for those who could not come.
Your second day climbs to the Drolma-La at 5,630 metres. An hour below the prayer flags the path crosses Shiva Tsal, a stony flat heaped with abandoned coats, shoes and cut hair. Pilgrims lie down here to act out their own death, then leave a garment, a lock of hair or a tooth behind to stand for the body they are giving up. Dying on the circuit is held to be good fortune, and the dead are given sky burial where they fall. Twice your path meets a Dikpa-karnak, a boulder that tests sin; under the first is a passage pilgrims crawl into to see whether they come out the far side. Some measure the whole circle with their bodies. Lying full length, the pilgrim marks where the fingertips reached, stands, walks to that mark and goes down again, so the trail is counted out body by body. Wooden boards are strapped to the palms so the hands slide over grit, with a leather apron and pads at the knees. The canvas gloves wear through and are replaced along the way, which is the other way of measuring the distance.
