But there is a knowledge which a mystic attains by means of the head and which prepares him to find his way to the truth. Reasoning is a faculty which the mystic uses, and which he may develop like any man of common sense, any practical man; the difference is only that the mystic does not stop at the first reason but wishes to see the reason behind all reasons. Thus in everything, whether right or wrong, the mystic seeks for the reason. The immediate answer, however, will be a reason which does not satisfy him, for he sees that behind that reason there is yet another reason. And so he progresses in the knowledge of all things, which is far greater than the knowledge gained by one thing. This is why neither wrong nor right, good nor evil, excites the mystic very much, neither does it greatly shock or surprise him. For everything seems to him to have its own nature, and it is understanding this which makes him feel at one with all that exists. And what can one wish for more in life than understanding? It is understanding that gives one harmony in the home with those near and dear to one, and peace outside the home with so many different natures and characters. If one lacks understanding one is poor, in spite of all that one may possess of the goods of this world, for it is understanding which gives a man riches.
