If it isn't based upon "belief," then why are you filled with preconceived notions and concpets BEFORE you can receive "the thing that is already yours?" Answer that one jonx or get the hell out of here and stop preaching your religion.
There is only ONE reason for the "Keys" and that is to feed their heads full of concepts and BELIEFS, so the first moment they taste their snot or see light because their rods and cones are forced to touch one another, they will ASSUME (read that: believe) it is something that it is not.
"....the experience one derives from the practice of Knowledge IS -- I repeat, IS -- in all ways based on belief...." Changes made by ME to make the statement utterly accurate.
