We were flying to a meeting. I was in the middle    36 .I found that the young woman sitting next to me was very   37  and deep in thought. Then I asked her where she was from, where she was going and   38  she did.
She was a student and had been attending   39 in Poland-----the homeland of her father. Then she told me sadly that her father had    40    . She had chosen to attend college in Poland   41 her father’s wishes and their relationship had been  42  .They hadn’t forgiven each other  43  he died.
She seemed so sad. I looked at her, trying to  44  some words to say. I asked her if she had forgiven  45  for not realizing her father’s dream. She answered that she couldn’t forgive herself  and felt so  46 .Slowly, I began to tell her about forgiveness. I encouraged her to  47  that because I believed her father wanted that too. She should forgive herself  48  how awful she thought she had been.
I told her about  49  I had done as a teenager for which I had felt guilty for many years. How I was  50  with the choice of forgiving myself or to  51  feeling guilty for the rest of my life. I had  52  to forgive myself . The light in her eyes went on. She began to understand that she was  53   forgiven and could forgive herself. She could be  54  and happy.
How about you? Is there anything in your  55  for which you feel guilty?
