Place your whole attention in the nerve, delicate as the lotus thread, in the center of your spinal column. In such be transformed.
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.
