“There is no doctor better than cheerful thought for keeping the body healthy”
Your body reacts to your mind and will, therefore, be a direct reflection of your thoughts, and disease and health, like circumstance, are rooted in thought. Sickly thoughts will express themselves through a sickly body and strong, pure and happy thoughts build a strong and graceful body. Your body is delicate and responds readily to your thoughts. A change of diet will not help you without changing your thoughts. If you want to protect your body, guard your mind.
Improve your health by changing your thoughts.
