Tibet is the highest stage in the world: the Potala above Lhasa, prayer flags over passes at 5,000 metres, and pilgrims measuring the earth in prostrations. Land of the gods, with the thinnest air and the biggest sky.
The Potala Palace is the fortress above Lhasa: over a thousand rooms built into the hill, red and white palaces glowing together.
Namtso is the sacred lake of Tibetan Buddhism, its surface at 4,700 metres, blue enough to touch the sky. And Everest Base Camp is the closest you can stand to the world's highest peak — watch the sunset gild the summit.
Butter tea is the plateau's fuel: strong tea churned with yak butter and salt, warming and rich at 3,600 metres. Tsampa, roasted barley flour, is mixed by hand with butter tea into the staple of every herder's day. And yak meat — dried, roasted or in stew — is the taste of the high pastures.
