Natural forces within us are the true healers of disease.

All excesses are inimical to Nature. It is safer to proceed a little at a time, especially when changing from one regimen to another.

We must turn to nature itself, to the observations of the body in health and in disease to learn the truth.

Fat people who want to reduce should take their exercise on an empty stomach and sit down to their food out of breath.... Thin people who want to get fat should do exactly the opposite and never take exercise on an empty stomach.

A wise man ought to realize that health is his most valuable possession.

Time is that wherein there is opportunity, and opportunity is that wherein there is no great time.

Men ought to know that from nothing else but the brain come joys, delights, laughter and sports, and sorrows, griefs, despondency, and lamentations. And by this, in an especial manner, we acquire wisdom and knowledge, and see and hear and know what are foul and what are fair, what are bad and what are good, what are sweet and what are unsavory…. And by the same organ we become mad and delirious, and fears and terrors assail us….All these things we endure from the brain when it is not healthy….In these ways I am of the opinion that the brain exercises the greatest power in the man.
