Guardian Angels: Protective, Familiar and Sympathetic Spirits
504. Can we know the name of our protective spirits or guardian angels?
“How can you know their names if they have no existence for you? Is it not possible that there are spirits whom you do not know of?”
a) But how can we call them if we do not know who they are?
“Give them any name you wish – that of any superior spirit with whom you identify and respect. Your guardian angel will answer this call because all good spirits are brothers and sisters who are always ready to assist one another.”
