An important warning is needed here. Wherever the idea of agnostic mysticism has been supported, the idea that there is no possibility of knowing the Absolute and so no communication of such knowledge, the reference is to ordinary human intellect. No positive result can come of its investigation into that which transcends it. But what intellect unaided cannot know, intuition--a higher faculty--can. It can discover its point of contact with the Absolute--its higher individuality, the Overself, even though it can go no farther and penetrate the Absolute. When intuition becomes active in this matter, it may or may not take the shape of a mystical experience. When it is developed by philosophic training, it expands into insight.
