Exercise
Close your eyes and picture a white light surrounding your entire body and extending a few inches out from it. Then recite the following prayer:
Archangel Michael, please surround me with your light and protection. Shield me from taking on any negativity and any energy that does not belong to me. Please keep me in a place of love. Thank you. Amen.
This exercise can even be done in a pinch with your eyes open if you are out and about somewhere. Nobody has to know you are doing it in your head, and it works just as well!
