Inhaling shows the power of absorption which is manifest in all living beings and in all objects. Little germs, worms, trees and plants all absorb, and in that way they breathe. Also in all living beings and in all things there is a tendency to put out an element which does not belong to them, in other words an element which their system will not assimilate. It is not only the inhaling and exhaling by the nostrils which accomplishes these two functions, absorption and rejection, but there are minute waves of the breath working in different directions of the body, which perform the above-said two acts in their own way and in their own rhythm of speed; for instance the tendency of stretching and contracting, the tendency of blinking the eyes, of expelling water and refuse from the body. When any of these subtle waves of the breath working in any direction of the body get out of order, than an illness originates in that particular part of the body, spreading its influence gradually to other parts.
