The New Encyclopedia of the Occult

The "occult" covers a pretty wide spectrum. Maybe start by educating yourself with the history and foundations of some of the areas that interests you and go from there. My recommendations would be to check out Real Magic by Dr Dean Raden and The New Encyclopedia of the Occult by John Michael Greer. https://a.co/d/02W62Eyt https://a.co/d/0i0kyL43
