If Qi were simply a force that flows through the body--sort of like spirit, or, on a more mundane level, blood, this would be easy to understand. But things get far, far, far more complicated when I begin to think about the fact that there are many different types of Qi and all are important for health.
For starters, we are all born with Qi. However, there's also Qi that we get from the food we eat and the things we drink--which makes diet especially important because it a bad diet can through off the Qi balance. Furthermore, the internal organs (heart, liver, lungs, etc.) generate their own Qi. And then there's the Qi that is fundamental to our gender, more commonly known as Yin and Yang-Qi. There's also heaven and earth Qi, which might be understood as the Qi that comes to us from the environment around it. The process of creating a living environment that produces balanced, healthful Qi is called "Feng Shui."
Are all these forms of Qi the same? I'm not sure. I'm not sure that "forms" is really the right term. My sense is that Qi is an energy, a force that flows through the universe and which is directed or misdirected by all of the different things we encounter: food, living conditions, psychological pressures, emotional states, conditions of our body, and a host of other elements.
For this reason, Ancient Chinese medicine (ACM) must be wholistic: it must treat the body as part of a larger, universalized system. Illness, properly understood, is caused by the mis-flowing of Qi, which can be caused by all kinds of things, both inside of us and outside of us. To restore a person to health, an ACM doctor must work to get the Qi flowing properly again.
This restoration might focus on the Qi that flows through the meridians of the body (acupuncture), Qi that flows through the body as a whole (tai Chi), Qi that flows through our living spaces (Feng Shui), Qi that flows through our spiritual life (Buddism?)...and I'm not sure what else.
I find this both complicated and cool. I like thinking about health as wholistic rather than as a simply result of microbes or viruses. It's empowering, in a way.
I've started reading a little about Feng Shui and will post about that soon.
