Quantum healing is healing the bodymind from a quantum level. That means from a level which is not manifest at a sensory level. Our bodies ultimately are fields of information, intelligence and energy. Quantum healing involves a shift in the fields of energy information, so as to bring about a correction in an idea that has gone wrong. So quantum healing involves healing one mode of consciousness, mind, to bring about changes in another mode of consciousness, body.
People are doing the best that they can from their own level of consciousness.
According to Vedanta, there are only two symptoms of enlightenment, just two indications that a transformation is taking place within you toward a higher consciousness. The first symptom is that you stop worrying. Things don't bother you anymore. You become light hearted and full of joy. The second symptom is that you encounter more and more meaningful coincidences in your life, more and more synchronicities. And this accelerates to the point where you actually experience the miraculous.
