"The physician must be able to heal himself."

"Eating alone will not keep a man well; he must also take exercise. For food and exercise, while possessing opposite qualities, yet work together to produce health."

"A physician without a knowledge of astrology has no right to call himself a physician."

"A wise man should consider that health is the greatest of human blessings, and learn how by his own thought to derive benefit from his illnesses."

"The best physician is he who can cure the disease without drugs."
