Wolfgang, the religions which have espoused the idea of many gods have generally done that because those many were symbols of the various aspects of the overall Divinity. Therefore the many were in fact, the One, but expressing through many aspects. That is certainly true of Hinduism. More serious students of that religion understand that the many are different aspects or facets of the One, while people with only a rudimentary understanding may not grasp that, since they are more literal thinkers.

The One is considered indescribable...but you can split it up into a pantheon of individual gods and goddesses which then are somewhat describable, as they relate to certain aspects of life.

Bill - "Supernatural" is a word that people normally use for a natural process that they don't understand. Everything is natural, but not everything is yet understood. They may, of course, also use it for something that they made up which in fact doesn't exist at all, except in their own minds. That often happens in religions.

Catholics, for instance, made up an idea a long time ago about "Papal Infallibility", a supernatural notion which I regard as utterly fictional.
