Qi /Energy (pronounced as Chi)
The concept of Qi is based on the ancient Chinese understanding of natural phenomena. That is, Qi is the most basic substance of which the world is comprised. Everything in the universe results from the movements and changes of Qi. Qi is the life force. Qi flows through 14 main meridians forming a network within the body, so that they work as one unit. Each meridian is connected to an internal organ, which follows a set pathway in the body. When a person is healthy, the Qi moves smoothly through the meridians. If however, the flow is blocked or the flow is too weak or too strong, then illness occurs.
YIN and YANG
Yin and Yang are an ancient Chinese philosophical concept. Yin and Yang are the two fundamental principles or forces in the universe, ever opposing and supplementing each other. For example: day and night, hot and cold, outside and inside, movement and stability, rising and falling, woman and man, summer and winter, etc. When YIN and YANG within the body are mutually supportive and in balance, the body is healthy.
