For centuries, philosophers have made mention of a “hidden reality” and then speculated as to its nature and how one might dispel illusion and bring what is hidden within sight. Those given to metaphysical speculation posit another world reached by passing through a portal. We have all seen the movies and television series inspired by the old tales of magical caves or fairy rings that, once entered, transport one to another place not of this Earth. Spiritual types speak of supernatural beings inhabiting spirit worlds “beyond” our normal ken. The belief gave rise to some of the world’s largest religions.
