The seventh angel is the highest of the inner energy centers, the crown station of consciousness, and its sounding is that center coming fully awake in a person. The number 7 symbolizes completion, the full ascent through the ranks of the body's spiritual centers from the base to the top of the head. When the last of these begins to vibrate, the hidden work is done: the mystery of God, meaning the divine buried in flesh, stands finished and known. The prophets who were told this are the earlier awakened faculties that always carried the promise of this completion within.
The long inner climb through a person's own centers reaches its end when the highest one awakens, and what was hidden inside the body becomes fully known.
The seventh angel: the crown center of consciousness at the top of the head, highest of the inner energy stations
The number 7: completion, the full ascent through all the body's spiritual centers from base to crown
The voice that sounds: the awakening vibration of that highest center coming fully alive
The prophets: the earlier awakened faculties within that carried the promise of this completion
