When you resolve to become pious, the devil in your nature cries out at you, "Tread not those paths, O confused one; distress and poverty will overcome you. You will be despised, let down by friends, you will regret it." Dread of the devil has bound their souls; the cries of the devil are the drover of the damned; the call of the Lord is a guardian of the saints.
RumiPut your thoughts to sleep, do not let them cast a shadow over the moon of your heart. Let go of thinking.
RumiEven though in the world you are the most learned scholar of the time, Behold the vanishing of this world and this time!
