Every thought of yours has literal value to you in every possible way. The strength of your body, the strength of your mind, your success in life, and the pleasures you give to others by your company- all depend on the nature and quality of your thoughts. You must know thought-culture.Thought-culture is an exact science. Man is created by thought. What a man thinks upon, that he becomes. Think you are strong; strong you become. Think you are weak; weak you become. Think you are a fool; fool you become. Think you are God; God you become. A man forms his own character, becoming that which he thinks. If you meditate on courage, you shall work courage into your character. So with purity, patience, unselfishness and self-control.
