Are You Willing to Forgive?
BLOG by Louise L. Hay
Whenever we are ill, we need to search our hearts to see what we need to forgive.
A Course in Miracles says that “All disease comes from a state of unforgiveness,” and that “whenever we are ill, we need to look around to see who it is that we need to forgive.”
I would add to that concept that the very person you find it hardest to forgive is the one you need to let go of the most. Forgiveness means giving up, letting go. It has nothing to do with condoning behavior. It’s just letting the whole thing go. We do not have to know how to forgive. All we need to do is be willing to forgive. The Universe will take care of the rest.
Let’s affirm: Love heals me. I center my thoughts on love and forgiveness, for myself and others.
So there you go~ give yourself the gift of forgiveness today! Remember: a lot of the time, the person we need to forgive the most--is ourselves!!!
Suggested task for when you are ready to take on Forgiveness: write out a list of all of the people who you need to forgive! For each one, say that you are willing to release yourself of the burden of unforgiveness to that person, and that you wish to set yourself and that person free.
Take your time. Forgivness really does make room for great blessings to enter your life! I have done it~ forgiven people who have betrayed me, cheated on me, etc.. I just decide that I don't want to be angry. I don't want to be an angry, bitter, sad person and carry that load on myself. I want to be able to talk to that person or think about them without angry emotions filling my energy field. After I do forgiveness techniques, those negative emotions are truly swept away. It's amazing!!
Allow yourself to give it a try.
