When we practice The Twelve Blessings, we are not only sending out love energy, we are actually changing ourselves as well. 

Dr. George King said in a lecture in 1983:

“If you meditate on something great, something glorious, you are bound to be affected in one way or the other—and this too is provable. So if you send out your power to they who work for peace throughout the world, without even thinking who they may be—without even knowing who they may be—you must receive from that group soul, from those people, a most beneficial energy which helps you: which changes your outlook, which changes your vibrations, which changes your aura, as well as helping those people who are working for peace—which is extremely important in this modern world.”
