There are three paths for the Gaia Method Earthways. You can take the Therapeutic Path, where you learn the Gaia Method for healing as part of your therapeutic practice; or you can take the Path of Earth Energy-worker, focusing on earth-work in the Landscape; or you can take the path of the Initiate, in service to the Divine Feminine. Each path incorporates the other, so if you decide that you feel drawn to being an Earth-energy-worker, then that will also include the Therapeutic path, and the Initiatic Path also includes the Therapeutic and the Earth Energy Path.
The only path that is not consciously chosen is the Initiatic Path. This is the initiation into the Temple of Artemis. If your soul is an Initiate, then that will be made clear at the beginning of your attunement. Otherwise, you can choose the Path you feel more drawn to. Your own soul knows what it needs and will guide you in that direction.
You are self-directed in your training, in that you follow your own guidance. The Gaia Method Earthways paths are for people who are already confident in their ability to channel energy and do not need instruction. That saying, we are writing some books that will help you if you are working on the Earth energy path or working with nature.
