Conception Meridian

The Conception vessel, or meridian, plays a major role in Qi circulation, monitoring and directing all of the Yin channels.

It forms a circular entity with the Governing Vessel.

In Qigong society, the Conception Vessel and the Governing Vessel are considered the most important among the Qi channels and vessels, and must be trained first.

Whereas the Governing meridian runs from the tailbone upwards along the mid-line of the back through the vertebrae to the head, this Meridian runs up the anterior (front) of the body, from the pubic area to the mouth.
