How do we Tibetans create our own sense of Place? Why should it matter?

How do Tibetans construct their own space and place, and what does cham have anything to do with this? While there are many socio-cultural ways in which Tibetans construct their own place, I focus my discussion on how Tibetans construct their own spaces through the masculine ritual practice of cham, and how Tibetans respond when those spaces and places are encroached upon.
