Under the deep blue sky, a Tibetan woman stops to rest on her pilgrimage, leaning on a stone wall. The long road winds into the distance, leading into the snow-capped mountains and eventually to remote temples. Serenity and satisfaction fill her face, despite the harsh journey ahead.The Tibetan Plateau, also called the “Roof of the World” for its altitude, is considered divine by Tibetans, who believe that traversing the snowy peaks on foot will purify one’s soul.
