Put your awareness on your spine
For this sutra, for this technique of meditation, one has to close his eyes and visualize his spinal column, his backbone. It is good to look up in some physiology book the structure of the body, or to go to some medical college or hospital and look at the structure of the body. Then close your eyes and visualize your backbone. Let the backbone be straight, erect. Visualize it, see it, and just in the middle of it visualize a nerve, delicate as the lotus thread, running in the center of your spinal column. IN SUCH BE TRANSFORMED.
If you can, concentrate on the spinal column, and then on a thread in the middle of it – on a very delicate nerve like a lotus thread running through it. Concentrate on it, and this very concentration throws you to your center. Why? The spinal column is the base of your whole body structure. Everything is joined to it. Really, your brain is nothing but one pole of your spinal column. Physiologists say it is nothing but a spinal column growth; your brain is really a growth of your spinal column. Your spine is connected with your whole body – everything is connected to it. In this spine there is really a thread-like thing, but physiology will not say anything about it because it is not material. In this spine, just in the middle, there is a silver cord – a very delicate nerve. It is not really a nerve in the physiological sense. You cannot operate and find it; it will not be found there. But in deep meditation it is seen. It is there; it is non-material. It is energy, not matter. And really, that energy cord in your spinal column is your life. Through that you are related to the invisible existence, and through that also you are related to the visible. That is the bridge between the invisible and the visible. Through that thread you are related to the body, and through that thread also you are related to your soul.
First, visualize the spine. At first you will feel very strange, you will be able to visualize it, but as an imagination. And if you go on endeavoring, then it will not be just your imagination. You will become capable of seeing your spinal column.
… IN SUCH BE TRANSFORMED. Once you can feel, concentrate and realize this thread, you will be filled with a new light. The light will be coming from your spinal column. It will spread all over your body; it may even go beyond your body. When it goes beyond, auras are seen.
