If you are ready to get rid of the pile of resentments you are carrying around, here's a nice exercise to try.  Write down the names of everyone in your life whom you feel has ever mistreated you, harmed you, done you an injustice, or toward whom you feel or have felt resentment, hurt or anger.  Next to each person's name, write down what they did to you, or what you resent them for.  Then close your eyes, relax and one-by-one, visualize or imagine each person.  Hold a little conversation with each one, and express the anger and hurt that you have felt.  Tell them exactly what they have done to upset you, and what you want from them.  Once you have done this, explain to them that now you are going to do your best to forgive them for everything, and to dissolve and release all constricted energy between you.  Give them a blessing and say, "I forgive you and release you.  Go your own way and be happy."  When you have finished this process, write across the paper, "I now forgive you and release you all."  Source: The Creative Visualization Workbook by Shakti Gawain.
