With all due respect, if you're going to have a "spirituality" thread (I think this thread should is misnamed per the OP) you probably shouldn't mix "religion" into it or you're going to duplicate the "Religion" thread that we already have? Perhaps this was supposed to be more of a "Philosophy" thread? If you look at the question that was asked by Amaro in the OP, he asked about Jung and The Collective Unconscious, which has absolutely nothing to do with religion and is actually related to psychoanalysis and probably unrelated to any of this, but maybe @Amaro 's point is reaching more toward metaphysics. And @ambergris ' point is certainly metaphysical.
See Metaphysics. Which is a philosophical discussion.
@Amaro also mentioned Idealism, which is also a philosophical discussion.
