well of course its interesting - someone put a lot of time and effort making that stuff up so that they could sell "healing sessions" to the gullible - which is actually very clever - i imagine they were someone who got sick of having to mix up fake medicines / potions and travel from town to town trying to cure baldness / agitation / all that ails you. So they probably though to themselves "i need a scam with lower overheads and less snake oil" and that was where nice clean crystal healing came from, unlike the potions he didn't actually hurt anyone and no one could test it very well so who could argue with him! BRILLIANT. people even come to him to no need to travel around conning the stupid the stupid quie up instead!
THEN things got even more interesting as the con artist realised that people really believed him and would pay to learn secrets of this alternative medicine - double brilliant! he could con the people who wanted healing, then he could con the people that wanted to learn to heal, they they could go out conning for him (but this is the really clever bit) WITH OUT ACTUALLY KNOWING THEY WERE CONNING PEOPLE!! Thats was the beauty of this chaps plan - people would do all the work for him, he'd take a cut and people would even respect him for his good work - it must have been hilarious for him... But then of course time passed, he got old and eventually passed away - so now the world is full of either con artist alternative medicine providers OR people so stupid they do not realise that the alternative medicine they provide is all made up (I'm not sure who is worse really)
anyway - I hope you enjoy being conned / conning people (depending on your IQ level)
