The Mystica is a very cool (encyclopaedic) site. It gives you the basics of various mystic, pagan, spiritual, paranormal, mythical, religious, theosophical, etc. beliefs and theories. It is by far one of the most comprehensive sites I have come across, as it covers such an array of topics and explains them in easy-to-understand language. Definitely worth checking out if youre interested in this kind of thing. (Go to the Topics section for a listing of articles.)
