Dear Jaguar,
I happen to agree with you. So many I get the feeling are written by would-be gurus to make money. Some of them I think play on fantasies and wishful thinking. And others really stink of spiritual materialism.
There are some good metaphyisical books out there, though. There are some people, IMO, who really are trying very hard to help others on their spiritual path. I just happen to think they're few and far between.
Best wishes,
Roxy
