Try this simple spiritual exercise to help you hear and see the two aspects of God, the Light and Sound.
Go somewhere quiet. Sit or lie down in a comfortable place. Put your attention on your Spiritual Eye, a point just above and behind your eyebrows. With eyes lightly shut, begin to sing a holy word or phrase, such as HU, God, Holy Spirit, or "Show me thy Ways, O Lord." But fill your heart with love before you approach the altar of God, because only the pure may come.
Be patient. Do this exercise for several weeks, for a limit of twenty minutes each time. Sit, sing, and wait. God speaks to you only when you are able to listen.
