O my soul, my only care, be on guard and learn to distinguish between the voices that smite your ears. Once you hear the voice of your Lord, abandon your dumbness and echo it with all your strength. O my soul, thou cavern of eternity, never allow temporal thieves to enter into thee and kindle their fire within thee. Be dumb when they shout at you. Anger makes its nest in the breast of arrogance and murder lies in the breast of anger.
All sins tend to murder, and none stands so close to murder as anger.
One-eyed earthly laws do not punish anger, because they do not see that anger kills. But Thy discerning law, O Glory of the realms on high, calls anger murder. I have striven, in sunlight and moonlight, to penetrate the mystery of Thy law and, once my striving began to wear away all my worldly hopes, I began to perceive how my anger towards neighbors was killing me. The children of anger are slaves, while the children of peace are sons. A son looks into the face of his father, and turns his own face towards that of his father.
