Energies with consciousness that are committed to supporting our current incarnation. With our guides the clue is in the name, they are not here to tell us what to do, only to offer guidance which we can chose to accept or reject (the beauty of free will).
They are not in a physical body as they are not incarnated and communicate through using our psychic sense and physical senses.
Working with spirit is always a two-way street, whilst we are learning and growing, so are the guides, or we are assisting them in understand how to better connect with people.
Why should connect with them?
People might wonder why they should bother to connect with their guides at all, personally I take advantage of any assistance through life I can. Your guides are assigned to you to help you navigate through this life, they know what your soul is aiming to achieve in this lifetime.
There are varieties of types of guides, you don’t need to worry about asking for specific guides, the right one for you will always make itself known to you. Your guides will try and help you from birth, however they are limited in how they can help you of the communication is one way, or you don’t ask them for help. Asking for help enables them to assist you in a more direct manner.
