“There are two kinds of silence: firstly, silence of the tongue, which consists of not speaking of other than God with other than God … and secondly, silence of the heart, which consists of refraining from all thought occurring to the soul that concerns any created thing. The one whose tongue is silent, even if his heart is not, lightens his burden. When someone’s tongue and heart are both silent, his innermost consciousness becomes manifest and his Lord reveals Himself to him. The one whose heart is silent but whose tongue is not speaks wisely. The one who possesses neither a silent tongue nor a silent heart remains under the domination of Satan and opens himself up to become an object of ridicule.”
—Shaykh Ibn al Arabi
