We define wellness as a state of integrity and energy flow. We define healing as clearing the energy that limits awareness and freedom, uncovering the light of self as Spirit.
You can be in a state of spiritual well-being, even if your body is physically un-well. When Gandhi was fasting to stop the riots in India, he was in a state of spiritual well-being, although his body was near death. Illness or body pain is an energy manifestation. It often alerts us to an issue of which we are not consciously aware. Healing is flow, and flow is change. We are all in a constant state of change. Nothing in the cosmos is meant to stand still. Mountains are slowly eroding to sand. Seasons end, and new ones begin. It is the same with your energy. It is meant to flow, always. When we block our energy flow as a result of resistance - fear, denial, - we limit healing. When the flow is limited and this is not acknowledged, it will most likely lead to physical illness.
The body is a manifestation of energy, of Spirit. Release the energy blockage, and you heal the body. You create your own reality. You have the ability to heal yourself. The idea that there are just a few special people on the planet who are healers is not true, we are all healers, we are all healers of self. No one else can do your healing for you, although you can certainly get a hand with the process. You can, moreover, give a hand to someone else to help in their healing. You will only heal what you are ready to heal, but there is no limit to how much you can heal. It is your choice.
