Most mystical enlightenments arising out of religious devotion alone or aspirational meditation alone are partial ones. Mysticism needs the support of knowledge to attain self-maturation and self-completion. It does not possess an adequate understanding of itself. The intelligent mystic will sooner or later feel the want of an adequate formulation of his own inward experience. But this can only be done through a metaphysical system, and if he seeks and finds the right one, which is the metaphysic of truth, he will find something which will be both a guiding star amid all the bewildering maze of his inner experiences and a supporting hand to help him keep his balance amid their confusing alternations. It will provide him with a definite means of assessing the truth-value of doctrines, ideas, movements, or masters. It will enable him to determine the proper moral attitude to adopt in whatever kind of situation he may find himself.
