Food for thought: Speech

Man's speech is the revealer of his heart. In whatever world the heart travels, man's conversation will revolve around that center. From his words you can understand in what world he is traveling, whether he is looking upward toward the realm of light or downward to the nether world, whether he is mindful or unaware, whether he is awake or asleep, whether he is alive or dead. For this reason His Holiness 'Ali says: 'Man is hidden behind his tongue. Out of the abundance of his heart does man speak.’
