December 3

If the health and well-being of the body be expended in the path of the Kingdom, this is very acceptable and praiseworthy; and if it is expended to the benefit of the human world in general—even though it be to their material (or bodily) benefit and be a means of doing good—that is also acceptable. But if the health and welfare of man be spent in sensual desires, in a life on the animal plane, and in devilish pursuits—then disease is better than such health; nay, death itself is preferable to such a life. If thou art desirous of health, wish thou health for serving the Kingdom. I hope thou mayest attain a perfect insight, an inflexible resolution, a complete health and spiritual and physical strength in order that thou mayest drink from the fountain of eternal life and be assisted by the spirit of divine confirmation.
