By the way, do you know Micro Cosmic Orbit in our body? The mid-line in our body that Governing Vessel is connected to Conception Vessel is called Micro Cosmic Orbit. Generally male's Micro Cosmic Orbit circulates down along Conception Vessel and up along Governing Vessel, and female's Micro Cosmic Orbit circulates opposite way, that is, down along Governing Vessel and up along Conception Vessel. This way of thinking is different from Chinese medicine's.
In Chinese medicine, Conception Vessel flows from the genital area to the mouth, and Governing Vessel flows from the coccyx to the mouth. There is a connection but the flow is opposite so there is no continuous circulation.
The concept of Micro Cosmic Orbit doesn't fit Chinese medicine, but I use the concept to decide treatment side. I will talk about how it works next time.
