Every sacred space implies a hierophany, an irruption of the sacred that results in detaching a territory from the surrounding cosmic milieu and making it qualitatively different.
Eliade defines divine irruption as the structural mechanism — hierophany — by which the sacred ruptures homogeneous profane space and constitutes a qualitatively distinct, cosmologically oriented place.
