If you are given to anger, worry, jealousy, greed, or any other inharmonious state of mind, and expect perfect physical health, you are expecting the impossible, for you are continually sowing the seeds of disease in your mind. Such conditions of mind are carefully shunned by the wise man, for he knows them to be far more dangerous than a bad drain or an infected house.
If you would be free from all physical aches and pains, and would enjoy perfect physical harmony, then put your mind in order, and harmonise your thoughts. Think joyful thoughts; think loving thoughts; let the elixir of goodwill course through your veins, and you will need no other medicine. Put away your jealousies, your indulgences, and you will put away your dyspepsia, your biliousness, your nervousness and aching joints.
