The typical religious enthusiast is the mystic. From Plotinus to Buddha, from Meister Eckhart to Emerson, the same doctrine has brought the same fruits of religious rapture. There is one God, and in contemplation of Him the soul becomes of his essence. Whether it is held, as by the Neoplatonists, that Being and Knowledge are one, that the procedure of the world out of God is a process of self-revelation, and the return of things into God a process of higher and higher intuition, and so the mystic experience an apprehension of the highest rather than a form of worship; or whether it is expressed as by the humble Beguine, Mechthild,--"My soul swims in the Being of God as a fish in water,'--the kernel of the mystic's creed is the same. In ecstatic contemplation of God, and, in the higher states, in ecstatic union with Him, in sinking the individuality in the divine Being, is the only true life. Not all, it is true, who hold the doctrine have had the experience; not all can say with Eckhart or with Madame Guyon, "I have seen God in my own soul," or "I have become one with God." It is from the narratives and the counsels of perfection of these, the chosen, the initiate, who have passed beyond the veil, that light may be thrown on the psychological conditions of mystic ecstasy. The most illuminating account of her actual mystical experiences is given by Madame Guyon, the first of the sect or school of the Quietists. This gentle Frenchwoman had a gift for psychological observation, and though her style is neither poetic nor philosophical, I may be pardoned for quoting at some length her naive and lucid revelations. The following passages, beginning with an early religious experience, are taken almost at random from the pages of her autobiography:--
