The distinction between psychotherapy and mysticism is a symbolic wall. It is a line drawn that makes spirituality circumspect and any spiritual assertion "symptomatic." Psychology is a form of behavior control that tells practitioners of "culture" exactly what the acceptable parameters of subjective experience and ritual will be. Currently, it countenances no version of "spiritualism" because society cannot "verify" to itself such arcane notions. This is the same as saying that society mistrusts its members, and if so, perhaps society is on a decline. For however "irrational" may be society's wellsprings, they are to be answered with better than derision.
