In Traditional Oriental Medicine the Lungs govern Qi and respiration. They’re responsible for inhaling Qi from the atmosphere, combining it with the Qi received from food and spreading the resultant useable Qi throughout the entire body. The Lungs are called the tender organ because they are the most external organs and they connect the body to the outside world. The Lungs are easily attacked by external pathogenic factors, in this case smoky, ashy, hot air. When the air we’re taking in is poor quality, we tire easily. Of course, when we’re breathing fine air and eating garbage we get tired easily, but that’s another discussion.
Ethics cannot be based upon our obligations toward [people], but they are complete and natural only when we feel this Reverence for Life and the desire to have compassion for and to help all creatures insofar as it is in our power. I think that this ethic will become more and more recognized because of its great naturalness and because it is the foundation of a true humanism toward which we must strive if our culture is to become truly ethical.
