When someone has deeply hurt you, it can be extremely difficult to let go of your anger. But forgiveness is possible—and it can be surprisingly    16    to your physical and    17    health.

“People who always forgive others   18    less depression, anger and stress and more hopefulness,” says Frederic Luskin, Ph.D., the    19    of Forgive for Good. “So it can help    20    on the wear and tear on our organs, reduce the wearing out of the immune(免疫的) system and    21    people to feel more vital.”

So how do you start the forgiveness? Try    22    these steps:

Calm yourself. To defuse your    23   , try a simple stress-management technique. “Take a couple of breaths and think of    24    that gives you pleasure: a   25    scene in nature, someone you love,” Luskin says.

Don’t    26    an apology. “Many times the person who hurt you has no    27    of apologizing,” Luskin says. “They may have wanted to hurt you or they just don’t see things the same    28   . So if you wait for people to apologize you could be waiting a(n)   29    long time.” Keep in mind that forgiveness does not necessarily mean    30    to the person who upsets you.

Take the control away from your offender. Mentally replaying(重播) your    31    gives power to the person who caused you pain. “   32    focusing on your hurt feelings, learn to look for the love, beauty and kindness   33    you,” Luskin says.

Try to see things from the other person’s view. If you empathize(把感情移入) with that person, you may    34    that he or she was acting out of ignorance, fear—even love.

Recognize the benefits of forgiveness. Research has shown that people who always forgive others will get more energy, better    35    and better sleep.

Don’t forget to forgive yourself.“For some people, forgiving themselves is the biggest challenge,” Luskin says. But it can rob you of your self-confidence if you don’t do it.”
