This may be apparent also from the fact in regard to the human body, that in its internal organs, cavities, membranes, both within and without, there are sensitive tissues in such abundance that nothing whatever can pass them by without their being aware of it. Quite obviously the same applies to the stomach, the liver, the lung. The tissues are shaped organically in different ways, so that the soul of a person knows and perceives whatever changes take place anywhere in the body, and according to what it so perceives, arranges the least details, inducing conditions suitable for healing whatever parts are out of order.
