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.
