The art of medicine has its roots in the heart.

We do not know it because we are fooling away our time with outward and perishing things, and are asleep in regard to that which is real within ourself.

Medicine rests upon four pillars - philosophy, astronomy, alchemy, and ethics.

Medicine is not only a science; it is also an art. It does not consist of compounding pills and plasters; it deals with the very processes of life, which must be understood before they may be guided.

If we want to make a statement about a man's nature on the basis of his physiognomy, we must take everything into account; it is in his distress that a man is tested, for then his nature is revealed.

What we should be after death, we have to attain in life, i.e. holiness and bliss. Here on earth the Kingdom of God begins.

Time is a brisk wind, for each hour it brings something new... but who can understand and measure its sharp breath, its mystery and its design?
