“One must realize that the human body is in some respects similar to a man-made machine. When the gas tank of a car goes empty, the engine immediately stops. The same law operates within the human body: When the body runs out of energy (starves, runs out of calories), it stops running and dies; and although man, who made the car, can refill its tank with fuel and put it to running again, he cannot do so with the human body. Once the heart stops beating, at that very moment life ceases and the body lies down until the One who created it starts it moving again.”
“When the crankcase of an engine becomes empty, but the engine continues running, then the machine breaks down and its usefulness ends. And as the life of a car is maintained by reducing the friction through means of lubrication, the life of a human being is kept up by Nature’s replacing the worn-out cells after the day’s task is done, while he takes rest in bed. Thus is he able to arise in the morning with renewed strength. But if he fails to provide the material which Nature needs in order to rebuild the worn-out cells and tissues, he, of course, suffers the consequences, as does the neglectful person who fails to drink enough water during the day (six to eight glasses), his blood will become impoverished and his system stagnant and clogged with waste material, ferments and decays. Too, if Nature is deprived of energy by which to throw off the toxins through the pores, kidneys, and the bowels, or to raise fever and endure the burning process of the wastes, then there is nothing to do but to give up trying-decease.”
“It is therefore necessary that Nature be well supplied with all the essentials (“Pure air, sunlight, abstemiousness, exercise, rest, proper diet, the use of water, trust in divine Power.” --MH 127:2) if one expects to maintain his usefulness unimpaired and to live his allotted life.”
“Moreover, no good engineer puts useless or needless parts into an engine, and if the user of it takes out any part, regardless how small and insignificant, the engine is made just that much less efficient. The same is true with the human body: Though the engineer can replace the missing parts in the machine which he designed and built, the surgeon cannot easily replace the body organs which his patient may cause him to remove. For example, one may remove only a setscrew from a machine and not affect its performance for the time being. At length, however, he will find that the machine fails to perform, and if he cannot replace the part, which he has taken out, the machine will become altogether useless. The same thing occurs, more or less, when one removes an organ from his body.” (Houteff 10,11)
