Breath and attention to breath are keys to self-emptying. Attending to the breath will carry you beyond the distractions of the mind and return you to the Greater Unity of God from which you arise and in which you dwell. Just as God breathed life into Creation, so God breathes into each one of us at this and every moment. Follow the breath back to God.
Darkness cannot be dissipated with more darkness. More darkness will only make darkness thicker. Only light can dissipate darkness. Those of us who carry the light are called to shine the light, to share it so that the world will not sink into total darkness.
