The Great Being saith: Human utterance is an essence which
aspireth to exert its influence and needeth moderation. As to its influence,
this is conditional upon refinement which in turn is dependent upon hearts
which are detached and pure. As to its moderation, this hath to be combined
with tact and wisdom as prescribed in the Holy Scriptures and Tablets.
