Learn to recognize the false dawn from the true; distinguish the color of the wine from the color of the cup. Then it may be that patience and time may produce, out of the spectrum-viewing sight, true vision, and you will behold colors other than these mortal hues, you will see pearls instead of stones. Pearls, did I say? Nay more, you will become a sea, you will become a sun traveling the sky.
RumiWhen 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.
Rumi
