Breath is crucial for life. Physical respiration goes on as a largely unconscious process as the body exchanges oxygen and carbon dioxide to power the activities of every cell in our bodies. Deliberate deep breathing will ensure that we take in enough oxygen and can calm feelings of breathlessness or fear. Conscious breathing used as part of a spiritual practice focuses the mind's attention and helps relieve stress on our bodies.
The divine life enkindled in the soul is the Light that has come into the darkness; it is the miracle of the holy night.
