Emanationism is an idea in the cosmology or cosmogony of certain religious or philosophical systems. Emanation, from the Latin emanare meaning "to flow from" or "to pour forth or out of", is the mode by which all things are derived from the First Reality, or Principle. All things are derived from the first reality or perfect God by steps of degradation to lesser degrees of the first reality or God, and at every step the emanating beings are less pure, less perfect, less divine.
