Every culture on earth has drawn a line between the ordinary and the sacred — a doorway, a mountaintop, a river's edge where something shifts and the air feels different. In this episode, we wander through the theology of thresholds: why humans across every tradition have designated certain places as thin, liminal, and alive with presence, and what happens to us when we cross into them. From the Japanese concept of *ma* to Celtic 'thin places,' from the desert fathers' wilderness to the Indigenous understanding of land as ancestor, we ask not just where the sacred lives — but what it means that we keep going looking for it.
