The angels tongues are pure praise

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.
