I found this at Starbridge Trust and thought it worthy to pass along:
1. Remember that angels have a life too. Make appointments when you want to talk to them for special reasons, unless you and your angel hang out together all the time anyway. Keep appointments. Apologize if you forgot your appointment. Angels are always forgiving. They really are.
2. Don’t take angels or what they do for us for granted. They have discretion as to what they do and do not do for us. While they would never deliberately cause you grief or take any action that would harm you, they are most willing to let you stew awhile in a difficult situation or let you struggle with it without helping you. It’s your life and you are responsible for it, they aren’t. They are helpers, companions, and protectors, but not your surrogate mom.
3. Thank angels for answered prayers, requests, and even the small gestures of kindness that they give without having to be asked. A verbal “Thanks Guys!” is what I say often – it helps bond our relationship and add respect to our interaction.
4. Make your needs known. While they can read your mind if they estimate that it is necessary, they are very private beings and deeply respectful of your “space” and your personhood. If you have a need, make it known to them. State it aloud, write it down, or just say it mentally but deliberately.
5. Be sincere. While angels have an immense sense of humor and love a good time and a good joke, they do not take notice of sarcasm, biting comments, off-colored asides, or personal barbs.
6. Know your intention in all that you do. Angels are deeply guided by your intention. What is your intention for having a conscious, personal, ongoing, co-creative sacred relationship with them.
7. Angels wish us to examine our motives, thoughts, behavior, and actions so that they all eventually flow with the light of the universe: all-loving and purposeful. This does not mean to become self-analytical or subject to every-minute-self-examination. It only means to know why you are thinking what you think, speaking the words you have selected to speak, behave as you do, and know why you take the actions that you do. Don’t be surprised if this takes most of your life to do!
