A term in the reading further defined by Eliade
Definition: s a term designating the manifestation of the sacred. The term involves no further specification. Herein lies its advantage: It refers to any manifestation of the sacred in whatever object throughout history. Whether the sacred appear in a stone, a tree, or an incarnate human being, a hierophany denotes the same act: A reality of an entirely different order than those of this world becomes manifest in an object that is part of the natural or profane sphere.
