The mystics have always known and practiced in a most perfect way the idea which is generally talked about in its most elementary form -- the idea that by repeating to oneself, "I am well, I am better, I am better," one becomes better. There are many who do not see any reason in it, but you will see that in time the most materialistic people will come to realize the truth that it is the attitude of mind, the willingness to be cured, the desire to get above one's illness, the inclination to fight against disorder, which help one to health.
