Spirit Guides are non-physical beings that exist in a different dimension than our physical reality. They are present to help us fulfill our spiritual contracts as well as help us live our day to day life.
We have Guides who are with us throughout our whole lives and Guides that come for specific projects with us.
They often appear as male or female but are actually just energy. They may have had physical lifetimes, and could possibly be someone you have known in another life.
Their job is to assist us. Being in connection with your Guides helps you make decisions for your highest good and feel accompanied in your life.
