One of the most beautiful compensations of life is that no man can sincerely try to help another without helping himself ~ Ralph Waldo Emerson
Surrogate tapping is when you tap for another person as if you are that person. There are various reasons for doing this which I won't go into here. People often ask "Am I interfering?" or "Do I have their permission?". As Gary Craig says "do we ask the permission of people before we send them a loving or an angry thought"? Rarely!!
I think if your intentions (energies) are aligned with the seven faces of intention which are: Creativity, Kindness, Love, Beauty, Abundance, Expansion and Receptivity, you won't go far wrong. In other words, if you wish for that person what God wishes for them and let that be your intention you can let go of the results. Let them be what they will be. Gary Craig also calls this "getting out of the way". I love this quote from Meister Eckhart: Be as a clear glass through which God can shine.
I also am of the belief that surrogate tapping (that can be done physically or mentally) is a form of prayer for that person and for you. Because we are all connected, the beautiful compensation is we all benefit.
It is not the magnitude of our actions but the amount of love that is put into them that matters ~ Mother Teresa
