If there is no paralell reality then how do Shamans conduct there work by going on vision quests with each other in other realms and how dot hey read minds. One fascinating book is the don Juan series by Carlos Castaneda. Maybe its gotta to do with exchange of particles and atoms in space that allows the telepathy and telekinetic powers or maybe its some other fabric of the universe. If you look at science it is all based on materialistic perspective. They work from one world view while actually trying to say that the other world views are completely wrong. for instance an ant cant describe what its world is like to a girraffe.This is what mdoern science is trying to do, they avoid actually attempting the spiritual practices of taking the psychedelic or undergoing the rituals too witness first hand this other reality that said people are talking about. They just stand there and object it without actually experiencing it. They also jsut trust there 5 senses with everything they have and never consider that what they are seeing is wrong or even giving possiblity of other senses.

Modern medicine sucks balls, its all BASED on plant medicine but in synthetic form soo that they can make a big buck off of it. The Shamans can heal somebody jsut as good as a doctor if not better. My mom took anti-depressants for 3 months and I saw first hand what the withdrawal effect was on her, she was terrible. she couldnt do anything but lay in bed and she is usually chirpy person always moving around doing stuff.

My point might be scattered, when I get back home (im on vacation) I will retype and clarify.
