The angels tongues are pure praise. Fire is also praise, the flickering flames are praise. Voice is praise, hearing is praise. All these images of praise are images of movement: fire moves, wind moves, tongues move, breath moves, hearing moves. In this praise there is a reverse movement toward God, perhaps mirroring. Energy moves out from God through the angels, and this movement back toward God in the form of praise is vibratory, dynamic, and meaningful.
We have not been raised to cultivate a sense of Mystery. We may even see the unknown as an insult to our competence, a personal failing. Seen this way, the unknown becomes a challenge to action. But Mystery does not require action; Mystery requires our attention. Mystery requires that we listen and become open. When we meet with the unknown in this way, we can be touched by a wisdom that can transform our lives.
