The bellows breath is the best method to release and surrender the spine to the draw of earth’s gravity. This is especially important in times of intense pressure and transformation.
The ego-based identity attempts to hold the spine away from its basic relationship with the earth, and this breaks the flow of energy between the spine and the brain. The ego has as its fundamental nature the reflex of separation, and attempts to control the flow of consciousness at the level of the body because the body is the ego’s basis of identity.
The whole idea of spiritual life, the whole idea of meditation, is not to form a belief system, but to arise spontaneously in the Self, to directly experience the subtle vibration of God within. It is the instrument of your being that has this experience, and relaxation is the key.
