What we mean is that this state, which we call the converse and communications of spirits, is of two kinds: one is simply imaginary, and the other is like the visions which are mentioned in the Holy Book, such as the revelations of St. John and Isaiah and the meeting of Christ with Moses and Elias. These are real, and produce wonderful effects in the minds and thoughts of men, and cause their hearts to be attracted. 72: HEALING BY SPIRITUAL MEANS Question.—Some people heal the sick by spiritual means—that is to say, without medicine. How is this? Answer.—Know that there are four kinds of curing and healing without medicine. Two are due to material causes, and two to spiritual causes. Of the two kinds of material healing, one is due to the fact that in man both health and sickness are contagious. The contagion of disease is violent and rapid, while that of health is extremely weak and slow. If two bodies are brought into contact with each other, it is certain that microbic particles will pass from one to the other. In the same way that disease is transferred from one body to another with rapid and strong contagion, it may be that the strong health of a healthy man will alleviate a very slight malady in a sick person. That is to say, the contagion of disease is violent and has a rapid effect, while that of health is very slow and has a small effect, and it is only in very slight diseases that it has even this small effect. The strong power of a healthy body can overcome a slight weakness of a sick body, and health results. This is one kind of healing. The other kind of healing without medicine is through the magnetic force which acts from one body on another and becomes the cause of cure. This force also has only a slight effect. Sometimes one can benefit a sick person by placing one’s hand upon his head or upon his heart. Why? Because of the effect of the magnetism, and of the mental impression made upon the sick person, which causes the disease to vanish. But this effect is also very slight and weak.
