I found a first edition copy of the Doors to Perception in a Newcastle, Australia used bookstore in ~2006-2008 for tens of Australian dollars. Not sure if it had any value, but I (naively I now realize) loaned it to my then-wife’s therapist who then stole it and lied by saying his dog ate it. I asked for the remainder. He again lied and said he already threw it away.
Joke is on him cos my now ex-wife had him dead to rights. He propositioned my then-wife multiple times and hired a former and later current female client he was in a relationship with as his secretary. (Just one person, not two different women.)
My then wife reported him and he lost his license to practice.
I consider his karmic debt still owes me a dogeared book lol
