If we are silent when we should speak, we are not living the Discipline of silence. If we speak when we should be silent, we again miss the mark.
Let the mouth also fast from disgraceful speeches and railings. For what does it profit if we abstain from fish and fowl and yet bite and devour our brothers and sisters? The evil speaker eats the flesh of his brother and bites the body of his neighbor.
Be not a slave of words.
Among a man's many good possessions, A good command of speech has no equal. Prosperity and ruin issue from the power of the tongue. Therefore, guard yourself against thoughtless speech.
The tongue may be an unruly member-- But silence poisons the soul.
Learning how to discipline your speech is a way of preventing your energies from spilling out of you through the rupture of your mouth, exhausting you and filling the world with words, words, words instead of serenity, peace and bliss.
