There are many other causes of illness. Among them the most unfortunate is the impression: "I have got an illness that can never be cured", for this impression is worse than a disease. In reality the soul of every individual, healthy or ill, is pure from any pain or disease, and it constantly heals mind and body, and if it were not for the mind and body, which create illness, a person would always be well. It is natural to be healthy; and all illness, pain, and discomfort are unnatural.
