In our most recent Master Keys we learned that the processes of the subconscious mind usually proceed without our personal knowledge or direction, and as long as we do not interfere with thoughts of fear, doubt and anxiety, the result is perfect. So, in a way, as strange as it sounds, if we can literally think nothing then we can remain healthy! However, thinking positive and healthy and having those ‘good vibrations’ should really enhance things. These laws of vibration, the result of our mental action, govern our health; mental therapeutics as it is referred to. People that have negative thoughts tend to be less healthy physically. I also feel that it is not only our own thoughts which can impede good health, but the thoughts of others around us.
