Ultimate Reality, if such an entity can be postulated, is ineffable. What we do know are the various forms of manifest reality, i.e., the complex ways in which Ultimate Reality acts in the domain (the 'ontological niche') of human life.

We have evidence how Being reacts when approached in different ways, but Being itself and the conditions of its acting in a certain way remain forever shrouded in darkness.
