According to James Allen, the human body is the servant of the mind. It obeys the operations of the mind, whether they be deliberately chosen or automatically expressed. At the bidding of unlawful thoughts the body sinks rapidly into disease and decay; at the command of glad and beautiful thoughts it becomes clothed with youthfulness and beauty. Strong, pure, and happy thoughts build up the body in vigor and grace. The body is a delicate and plastic instrument, which responds readily to the thoughts by which it is impressed, and habits of thought will produce their own effects, good or bad, upon it.
James then said, change of diet will not help a man or woman who will not change his thoughts. When a man or woman makes his thoughts pure, he no longer desires impure food. Clean thoughts make clean habits. The so-called saint who does not wash his body is not a saint. He who has strengthened and purified his thoughts does not need to consider the malevolent microbe. So here is my question can you change and willingly remove the negative thoughts in your life and introduce positive, blissful thoughts within yourself to produce an abundance of joy?
