"What do we really know about a human being? We can describe his physical body, we can touch him, but the entity which formed this body and which inhabits it can neither be described nor touched. Matter gives us a certain idea of reality, but it is not reality itself. If you truly wish to make a profound change in your physical body, therefore, you should not spend much time on it, because it is not the reality, but only a consequence of it. What is real is feeling, thought and, beyond them, the spirit which, by means of thought and feeling, has the power to mould the body. It is to these, then, that you must address yourself. In response, they will work on the matter of your physical body, which little by little will begin to obey and to transform itself. "
