There are some people who have no spirit; that is to say whose spirit is still buried. They do not care, they are quite happy, although they do not know what true happiness means. But for others who are very much aware of their spirit there is nothing more difficult than to keep it in the right condition; yet no sacrifice is too great and nothing we can do is too much to keep the spirit in tune. The mystic, therefore, trains his spirit; it is the training of his own spirit that enables a man to help the souls who come to him.
