Rumi Quote

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.
