The whole thing is of course unscientific, but that is hardly a relevant criticism of a religious movement. What I find frustrating is that it is all so vague. There does not appear to be any discernible consensus as to what is true or false even in a purely spiritual sense, or even as to whether such concepts as "true" or "false" apply. The imagery is all nice and soothing, but is there anything more solid than that to it?
