Let go of anger and resentment, and feel yourself healed. You don't need to forgive the action, just the person - so that you can be at peace.
By drawing this card, your angels guide you to release anger and irritation. They realise that you may be perfectly justified in feeling angry. Yet, they ask you to look at the high price you pay for being the vessel of anger.
Forgiveness does not mean, "What you did is okay to me." It simply means, "I am no longer willing to carry around pain in response to your actions." When we hold unforgiveness in our hearts, we only punish ourselves, after all. Your angels will help you release unforgiveness if you will just ask for their assistance.
