One who conceives God as existing outside his own being, however defined, unwittingly limits God and so worships a god that is less than Absolute, less than All in All, less than One. For in so excluding God from his own arbitrarily presumed or defined mental boundaries as subject (self), he unwittingly relegates God to the status of an abstract object (other)—to being just another mental artifact—while installing himself on the inner Throne of God, as the central focus of his attention. In so doing, he also necessarily excludes the possibility of experiencing direct conscious union with God, for he is now conceptually “in here” and God “out there.” An impenetrable mental veil or curtain of conceptual ignorance is thus firmly established between he and God—a barrier of sense reinforced belief in his own fundamental separation from God and all else.
