Here is what my thesaurus brought up;
Mystic: spiritualist, medium, shaman, sage
Mysticism: religion, theology, religious studies, spirituality, holiness
You are choosing the medium, shaman part and igmoring the spirtualist,
plus you are ignoring all the difnitions of mysticism — none of which have to do with the ococult.
Oops.
ococult.
occult
I believe that over time, the definition is shifting to have less of an occult overtone...though that part of the definition still remains officially there.
