阅读下面的短文,请根据短文后的要求答题(请注意问题后的字数要求)

To forgive (宽恕) may be great, but no one ever said it was easy. When someone has deeply hurt you, it can be very difficult to let go of your complaint. But forgiveness is possible — and it can be surprisingly beneficial to your physical and mental health.

So how do you start forgiveness? Try following these steps:

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

Don’t wait for an apology. “Many times the person who hurt you has no intention of apologizing,” Luskin says. “They may have wanted to hurt you or they just don’t see things the same way. So if you ______________________, you could be waiting an awfully long time.”

Take the control away from your offender. Mentally replaying your hurt gives power to the person who cause you pain. “Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you,” Luskin says.

Try to see things from the other person's perspective. If you understand that person, you may realize that he or she was acting out of ignorance, fear —even love. To gain perspective, you may want to write a letter to yourself from your offender’s point of view.

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 forgive yourself.”
