Kodhana Sutta -- An Angry Person (paraphrased)

Seven things happen to people who are angry, which end up making their enemies happy:Some people wish that their enemies become ugly. But when people are angry, even if they are well bathed, beautifully dressed, and their hair neatly cut, they become ugly themselves! This is exactly what their enemies would wish for them!Some people wish that their enemies sleep poorly. But when people are angry, even if they sleep on luxurious beds, with white sheets, fluffy pillows, and beautiful blankets, they will sleep poorly because of their anger. This, too, is exactly what their enemies would wish! Some wish that their enemies not profit in business. But when people are angry, they become confused: When they suffer a loss, they think they are making a profit; when they make a profit, they think they are suffering a loss. This leads to constant worry, which is exactly what is enemy would wish!Some wish that their enemies not have any wealth. But when people are angry, even if they start out with wealth that they have worked hard to accumulate, they will behave badly and may wind up in jail or paying fines for their misbehavior, and eventually lose their fortunes. This is exactly what his enemy would wish!Some wish that ther enemies lose their reputation. But when people are angry, whatever reputation they have, and however well earned it may be, will disappear, which is exactly what their enemies would wish!Some wish that their enemies have no friends. But when people are angry, their friends and relatives avoid them because of their temper. This is exactly what their enemies would wish!And finally, some people wish that their enemies would go to hell. But when people are angy, they commit all kinds of sins, in their behavior, their speech, and in their minds. When they die, they may find themselves in hell, which is exacly what their enemies would wish!These are the seven things which happen to angry people, which end up making their enemies happy
