The matter of eating naturally is a very simple one; there is nothing in all the foregoing that cannot be easily practiced by any one. This method, put in practice, will infallibly result in perfect digestion and assimilation; and all anxiety and careful thought concerning the matter can at once be dropped from the mind. Whenever you have an earned hunger, eat with thankfulness what is set before you, chewing each mouthful to a liquid, and stopping when you feel the edge taken from your hunger. The importance of the mental attitude is sufficient to justify an additional word. While you are eating, as at all other times, think only of healthy conditions and normal functioning. Enjoy what you eat; if you carry on a conversation at the table, talk of the goodness of the food, and of the pleasure it is giving you. Never mention that you dislike this or that; speak only of those things which you like. Never discuss the wholesomeness or unwholesomeness of foods; never mention or think of unwholesomeness at all. If there is anything on the table for which you do not care, pass it by in silence, or with a word of commendation; never criticise or object to anything. Eat your food with gladness and with singleness of heart, praising God and giving thanks. Let your watchword be perseverance; whenever you fall into the old way of hasty eating, or of wrong thought and speech, bring yourself up short and begin again. It is of the most vital importance to you that you should be a self-controlling and self-directing person; and you can never hope to become so unless you can master yourself in so simple and fundamental a matter as the manner and method of your eating. If you cannot control yourself in this, you cannot control yourself in anything that will be worth while. On the other hand, if you carry out the foregoing instructions, you may rest in the assurance that in so far as right thinking and right eating are concerned you are living in a perfectly scientific way; and you may also be assured that if you practice what is prescribed in the following chapters you will quickly build your body into a condition of perfect health. CHAPTER XIV. BREATHING. The function of breathing is a vital one, and it immediately concerns the continuance of life. We can live many hours without sleeping, and many days without eating or drinking, but only a few minutes without breathing. The act of breathing is involuntary, but the manner of it, and the provision of the proper conditions for its healthy performance, falls within the scope of volition. Man will continue to breathe involuntarily, but he can voluntarily determine what he shall breathe, and how deeply and thoroughly he shall breathe; and he can, of his own volition, keep the physical mechanism in condition for the perfect performance of the function.
