O thou spiritual clarion! The voice of the physical clarion may travel the distance of
three miles, but the harmony of the spiritual Clarion reacheth to the East and
the West. The effect of that is only in the bodies; but the effect of this is
in the spirits. The first proclaimeth the time of prayer; the second announceth
the appearance of the Most Great Resurrection. That hath no conscious knowledge
of its own voice; while this is exhilarated and rejoiced by its own melody.
