Celtic tradition holds that the earth’s geography contains “thin places.” Heaven and earth are only three feet apart, the adage goes, but in such liminal zones, the distance is even less. Thin places are thought to be those areas where the temporal and spiritual converge, where the invisible and visible worlds coalesce. It could be a mountain or a river, some geographic axis, some threshold of rock, earth, or water, some pleat in the river or fold in the land that has the capacity to advance human spirit. It might be a place that becomes the site for a temple or monastery or shrine, but it could just as well be the snow settling on a frozen lake, an eclipsed sky, an unexpected conversation. Thin places refer not simply to geographic features but to how these allow people spatial and psychic realignment.
