Pilgrimage is premised on the idea that the sacred is not entirely immaterial, but that there is a geography of spiritual power. Pilgrimage walks a delicate line between the spiritual and the material in its emphasis on the story and its setting: though the search is for spirituality, it is pursued in terms of the most material details – of where the Buddha was born or where Christ died, where the relics are or the holy water flows. Or perhaps it reconciles the spiritual and the material, for to go on pilgrimage is to make the body and its actions express the desires and beliefs of the soul. Pilgrimage unites belief with action, thinking with doing, and it makes sense that this harmony is achieved when the sacred has material presence and location.
