According to Wikipedia on Hermeticism:
As stated above In Hermetic religion the supreme Deity, or Principle, is referred to variously as 'God', 'The All', or 'The One'. The absolute is the central focus of Hermeticism and therefore it is difficult to assign it a position among the traditional Theistic religions, or along the monotheistic and polytheistic spectrum.
Hermeticism transcends both Monotheism and Polytheism as well as Deism and Pantheism within its belief system, which teaches that there is a transcendent God, The All, or The One, of which we, and the entire universe, participate.
"That which is Below corresponds to that which is Above, and that which is Above, corresponds to that which is Below, to accomplish the miracles of the One Thing".
I see a lot of similarity with Taoism. Is there similarity between religions because the Truth reveals a little of itself to everyone or because humanity is bound by similarities?
