All aspects of human nature need to be illumined and equably balanced if the illumination itself is to be total, pure, and reliable. This statement is no more, and no less, than the truth. Yet ignorance of it is widespread among would-be mystics and even among real mystics. If there is contradiction between their results, it is because they too often experience the illumination fully through their feelings, to a limited extent through their wills, and hardly at all through their intellects.
