Manly P. Hall

"All religions have a hidden or esoteric side. The same may be said of all the divisions of a religion. The esoteric doctrine we see in a religion depends upon the esoteric eyes we have developed in our own spiritual natures. They who look through the eyes of form can see only form and in religion only the history of people now dead and countries now unknown; while to them who have evolved the spiritual sight, the life behind the form (the truth behind the allegory), is visible. All religions are steps in the unfoldment of one truth and they only clash when their spiritual ideals are crystallized into material forms."
