What is the best book to learn about the occult?

Not certain which posts you are referring to but I do not identify with 'atheism'. I just do not subscribe to the commonly accepted conceptualizations of the term 'God' - as an externalized, personified deity/entity with human-like traits/characteristics that exists somewhere else and separate from all of creation.

My thoughts/feelings/beliefs would probably align more closely with some ideas found in deism, pantheism, pandeism, etc - although I do not identify exclusively with those schools of thought or claim those labels/titles. I am very spiritually-minded and prefer to explore/consider various schools of thought and I will choose to relate to that which resonates or speaks to my heart. I guess with some people (not suggesting you here) if you do not accept their version or conceptualization of the term 'God' - then they are likely to perceive of you or label you as an atheist. In fact I've run into that quite a bit on here.

I do not read texts about the 'occult' that individuals often refeernce, but I just wanted to comment above about about the psychological reaction to the term as it relates to many individuals' perception of it. My interests are studying the nature of consciousness & the human mind, emotions, transpersonal psychology, and exploring ideas about the nature of this 'reality' (quantum theory, holographic universe theory, etc).
