Touching My Father's Soul highlighted the tensions that arise from the competing interests of economic need, commercialization, and spirituality on Everest. Many Sherpas rely on the commercialized mountaineering industry to support their families. However, the commercialization of Everest has led to the development of attitudes which imply expectations of a successful summit bid. These attitudes, often held by clients on guided expeditions, often conflict with Sherpa spiritual beliefs, which say that the goddess inhabiting the mountain will determine successes and failures. Sherpas will not climb without performing a puja, a ceremony that asks the gods for permission to climb and safe passage on the mountain. Because of economic necessity, Sherpa who work on Everest seem to be stuck in a bind between upholding their spiritual beliefs and contributing to the commercialization of the mountain.
