In Realization Process, one of the main ways that we realize nonduality is through the subtle vertical core of the body. This is a slender channel that can be accessed from the center of the bottom of the torso (and below) to the center of the top of the head (and above). We enter into this channel by finding points within the core of the body, and initiating the breath within these points. We can enter into the subtle core of the body anywhere along it, but in Realization Process, we enter mainly through the center of the head, chest and pelvis.
The center of your head can be found approximately between your ears, in the very center of the internal space of your head. In other words, I do not mean the center between the brows or the top of the head. When you enter into this point in the center of your head, you will feel a subtle vibration down through your whole core. Most people find this point too high up in their heads. If you can feel the vibration downward through your whole core, you know that you have found the point in the center of your head.
The points in the center of the chest and pelvis are found by focusing inwardly as deeply as you can without strain, in your chest and pelvis. All of the points within the subtle core of the body can be recognized by their subtle vibration. It is important to find the point by the feel of it, rather than by an anatomical location.
The subtle core of the body is mentioned in several Asian spiritual disciplines. It is called the “central channel” in Tibetan Buddhism, and “shushumna” in Indian Yoga. In Yoga, shushumna is said to consist of three channels, nested within each other. The innermost channel is considered to be the most subtle channel. In Realization Process, we also penetrate with our focus into the innermost core of this channel. Eventually we feel that we are living within this channel, that this channel is part of who we are.
Wherever we enter into the subtle core of the body, it feels as if we have entered into our whole being. Also, when we breathe within any point in the subtle core of the body, the breath produces a subtle vibration throughout the whole body. It has often been said that there is no center in the realization of nonduality. It can also be said that the center of nonduality is everywhere. Once we become adept at finding the innermost core of our body, we find that we can enter into our whole body/being at once through anywhere in our body. We can also feel a resonance between the subtle core of our own body and the subtle core of another person’s body. The center that is everywhere in our body is the same center that is everywhere in another person’s body.
The subtle core of the body is an entranceway into nonduality, into the mutual transparency of self and other. The subtle core is an entranceway into the wholeness of our own body/being and the oneness that transcends our individual being.
From the subtle core of the body, we are disentangled from all of the content of our experience. We can let go of our grip, our limiting grip on our experience. This means that our thoughts, feelings, sensations and perceptions can flow more fluidly. We can allow life to happen, and we are present for life happening, we are open to its movement.
