YOUR SPIRIT GUIDES
Everyone has a group or "band" of Spirit Guides around them. Your Guides have been with you since birth. It is not uncommon for the Guides that are with you now to have also been your Guides in previous lifetimes as well.
A Spirit Guide has lived on the Earth before, but through many incarnations has learned and perfected all possible earthly lessons. Therefore they no longer need to take a human form and go on to become Spirit Guides for those of us still learning on the Earth Plane.
The purpose of your Spirit Guides is to help you progress along your own unique, spiritual path. Your Guides will not impose their wills on you. So once you have learned their names and abilities, it is up to you to start developing a relationship with them. With the help of an experienced Psychic Medium, you can learn the names of your Guides, along with the unique abilities each one of them possess.
There are also spiritual reasons why you have the Spirit Guides around you that you do. When your Spirit Guides where living on the Earth, they also had lives as unique and individual as those us living on the Earth now. So you and your Spirit Friends are vibrationally drawn together according to the commonality of your life experiences. Theirs when they were living on the Earth and yours that you are experiencing now. This gives you Guides the knowledge and experience to help you, since your Guides have already been through these experiences when they lived on the Earth.
