Sometimes an individual expression stays for hundreds of thousands of years in your universe, or some for only a brief time. It is their choice. Their existence is the harmonious flow of thought, light, sound and color, and with ability to take form. There are more choices of form in your universe then anywhere else. These beings are immortal moving through many existences and many levels of consciousness.
Angels are a beautiful existence of light and appreciation for the joy of being.
The Angelic Kingdom expresses the joy of just being. Angels have been with you since the beginning of your world. They are not only a non-physical vibrating form that you may occasionally connect with or feel their presence, but angels have also taken a 3rd dimensional terrestrial form at times. This has been the choice of an angel when they felt that type of nurturing, gentle guidance and love could help you to reach a next stage of your own internal development, your own spiritual awareness, or your expansion of consciousness. You may not be aware that there is an angelic presence among you and know that the angelic presence will only stay briefly on your planet.
