“What are ye men in your own powers but nothing? If you wish to obtain strength take it from faith. If you have faith as big as a mustard seed, you will be as strong as the spirits, and although you now appear as men, your faith will make your strength and power equal to the spirits such as were also in Samson. For by means of our faith we become spirits ourselves, and whatever we accomplish that surpasses our (terrestrial) nature is done by the power of faith acting through us as a spirit and transforming us into spirits.” (“De Origin, Morb. Invisib.” Introduction.) Man, even if he obtains occasionally a glimpse of divine truth, is only too prone to forget it again at the next moment, as the action of his terrestrial mind is stronger in him than that of his spirit, and it seems therefore necessary to be reminded over and over again that the faith of which Paracelsus speaks is not the illusory faith of the brain, the product of speculation, but a power belonging to those few living spirits walking within this sleeping world. As physical powers belong to the physical and terrestrial man, so spiritual powers belong to the spiritual man who must be born before he can know and exercise these powers. As yet there appear to be few even among our eminent scientists and successful practitioners who have become regenerated in the spirit of truth and filled with the light of divine wisdom, and if there are any such, we would ask all the students of medicine to follow their example and by learning the great art of self-control to become masters over their own nature and over the nature of others. Humanity is only one, and the realization of this truth will open a new field for the science of medicine in the future. That part of us which lives within the heart of others is our own truest and “most profound Self.”[9] If this self, which lives in the hearts of others, has awakened to its own consciousness, it will realize its own universal existence and its own power to act within those in whom it lives. Thus the physician, having become self-conscious of his own higher nature, will become a saviour for all the rest of mankind, not only in regard to their moral evils, but also in regard to their physical ills; for the spirit and soul and body of man do not live separately; they are one organic whole, as is the body of humanity, even though the personalities constituting that body are separated from each other by the illusion of form. II. THE FOUR PILLARS OF MEDICINE. The pillars upon which the practice of modern medicine rests, are:— 1. _A knowledge of the physical body of man_, the arrangements of its organs (anatomy), their physiological functions (physiology) and the visible changes which take place in them when a disease becomes manifest (pathology).
