Angels show themselves by extending an open heart, an open mind, an outstretched hand, giving a warm hug and above all, concern for our well being. The next time you are going through a difficult time in your day, or life, pay attention. We just never know when they are going to pop up.
While on the subject, the next time you feel that tug to help another, take time out of your life to actually care about someone - more than yourself, or just need to call someone, for no particular reason, DO IT!
It is in those times, the angels may be using you to create some of their warm magic to help the good vibrations flow more freely around our planet.
