First, energy healing is not a substitute for professional medical care. It does not have to be an either/or situation. Many medical doctors are amicable to their patients receiving these types of treatments in conjunction with their recommended care.
As with any type of treatment no results are guaranteed due to the dynamic nature of the human body, healing and various health conditions.
It is commonly known that stress is the leading underlying cause of many conditions. Energetic healing while not entirely understood, is known to be a fabulous way of de-stressing and gaining rational perspective. Alleviating and eradicating stress and stressors in one's life is a huge step towards healing on many levels.
Energetic healing addresses issues known and unknown for the purpose of bringing the person back to a conscious and unconscious state of oneness thereby restoring balance and function. As to exactly how this will manifest cannot be determined or guaranteed. The intention is for the healing for the highest good.
