Tibetans believe, once in their life, a pilgrimage to Lhasa is of exalted purpose and moral significance. Therefore, we see people like this, especially in spring and autumn, on their journey of faith, sometimes thousands of miles long, kowtowing every few steps. The pilgrims' foreheads normally have black scars, impaired by rough roads, and their determination shocks even stone hearts--- Do not be mistaken, not all Tibetans do this, most of these pilgrims are poor people from the most remote corners of Tibet. During my journey, I had conversation with all kinds of people and watched many things, a lot of monks in the temples are corrupt and dark beyond description, faith is the least of their concern. But these pilgrims on the roads, they always send chills down my spine in a spiritual way.
