As Frequently as Possible, Hold Thoughts of Forgiveness in Your Mind
In muscle testing, when you hold a thought of revenge, you’ll go weak, while a thought of forgiveness keeps you strong. Revenge, anger, and hatred are exceedingly low energies that keep you from matching up with the attributes of the universal force. A simple thought of forgiveness towards anyone who may have angered you in the past without any action taken on your part will raise you to the level of Spirit and aid you in your individual intentions.
You can either serve Spirit with your mind or use that same mind to divorce yourself from Spirit. Married to intention, you connect to that power. Divorced, your self importance, your ego, takes over.
