When you see anyone complaining of such and such a person's ill-nature and bad temper, know that the complainant is bad-tempered, forasmuch as he speaks ill of that bad-tempered person, because he alone is good-tempered who is quietly forbearing towards the bad-tempered and ill-natured.
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
