Generally speaking, the purpose of healing is to release stuck energies from the body to regain physical and emotional strength and clarity of the mind. Messages and insights channeled are more likely to be relating to the energy blockages detected during the healing e.g. possible causes, remedies etc.
Compared to a reading per se, energy healing tends to be more broad-based and offers longer-term benefits by clearing out distorted and old vibrations which often block our way towards sustainable expansion and strengthening of our spirit and positive qualities. In some cases, for the effects to be visible and long-lasting, healings may be need be repeated and reinforced over a period of time. Reason: it is not easy for humans to always think only of the positive and so, we tend to oscillate between high and low frequencies.
