"Victor Turner uses the term 'liminality' to refer to any condition outside, or on the margins of, ordinary life, and which is potentially sacred. A visit to a sacred place at a time outside ordinary profane time, such as a pilgrimage on a feast day, is a particularly liminal occasion."
Carleton Jones defines "liminal" thusly: "A liminal area is an area that is in between. In a spiritual context, a liminal area can exist between two different levels of consciousness or experience. At Loughcrew, it is likely that the people who built the tombs lived in the surrounding low- lands rather than on the hilltops alongside the tombs and that they regarded the hilltops with their cairns as a liminal area or a threshold between the land of the living and the land of the dead ancestors."
