We can build and strengthen the spirit by purifying our body. One may die from a hunger that comes from the body. However, entire civilizations have collapsed into ruins from a hunger of spirit. Treat your body as a temple. Do not bring trash into it. Take great care of it. It is a priceless treasure. Seek purity in the mind and purity in the body. If we are kind to our mind and body, we can cultivate inner and outer strength. Our chi can flow strongly, and inner harmony can be gained.
