“Your body is the instrument of your mind. In your emotions, the spirit and the body come closest to being one. What you learn spiritually depends, to a degree, on how you treat your body. That is why the Word of Wisdom is so important.
“The habit-forming substances prohibited by that revelation – tea, coffee, liquor, tobacco – interfere with the delicate feelings of spiritual communication, just as other additive drugs will do. Do not ignore the Word of Wisdom, for that may cost you the “great treasures of knowledge, even hidden treasures” promised to those who keep it. And good health is an added blessing.”
