The Thrusting Vessel is the key to spiritual experience as it runs along the course of the spinal cord through the ‘marrow’ and reaches the brain directly. Thus whilst we may manage indirect access via the Governor and Conceptor vessel, it is only via the Thrusting Vessel that we gain access directly to brain functions.
I think the Thrusting vessel mirrors the course of the dura mater and the cerebrospinal fluid.
The Thrusting vessel is a Yin channel.
Yet again, one course of energy in the Thrusting vessel flows from one crucial trigger point found at the perineum . As we can see, the sacrum [and coccyx] is yet again the junction where the Qi enters the spinal cord and reaches up to the brain.
You can also see from the diagram that the Thrusting vessel tracks the course of the ‘kidney channel’ after which it ascends through the abdomen and disperses in the chest. If you draw on this source of energy to lead it up the spine, it may draw on the energy supplying the kidney.
One of the functional purposes of the Thrusting vessel is to connect, to communicate and to mutually support the Conception vessel and by so doing regulate the energy in the kidney channel [shown as K below]. The kidneys are considered a vital organ in Chinese medicine – as they are in western medicine!
But they provide a gateway through to a pool of energy – Yin energy that can be used in boosting Yin to exchange with the Yang energy and getting it really flowing round the system.
The course of the Thrusting vessel is shown in the diagrams below. The Thrusting vessel is heavily used in 'Marrow Washing', a Qigong technique.
As you can also see from the diagram, there is a path that descends the inner thigh, follows the medial margin of the tibia and leads to the bottom of the foot, another course can lead eventually to the big toe, providing another path through which to redirect energy. Both massage and walking [or cycling – cycling being extra effective as the saddle can be made to press on the perineum] help to produce an excess of Yin energy here which can be redirected.
