They can vanish just as quickly if we slip out of the spot of light from which we saw them. There is no way to separate this spiritual program from prayer. When one is in the spirit or seeking to be in the spirit one is in prayer. To be with God is to be deeply comfortable with oneself. But what one is uncomfortable with is the false self, the constructed self, the betraying and simpering and miserable and mean spirited and tiny, complaining.
Prayer is the soul seeking life.
True life becomes a river of prayer. The underground river of the spirit nourishes the heart, and the plants of virtue are continually watered. The dirty mind is continually cleansed, the cloudy eyes are cleared to see. This is not unreality we are talking about. People who see this way walk in the midst of evil and live clearly through the most abusive of situations.
