This question has been puzzling me for some time, because to us healing energy is the energy an individual body and soul requires on that day to resonate - perfect pitch for perfect health and wellbeing.
So in all probability everyone will require slightly different frequencies of energy for themselves on any particular day.
I think the question really stems from the various names people have given to their methods of bringing the healing energy through. The techniques and words they use to prepare themselves to channel the healing energy into the room or person. For example Reiki, Spiritual Healing or Reconnective healing to name but a few.
At the Healing Room we like to include healers from all different backgrounds. We ask them to leave their egos at the door and come and hold the space to channel the healing energy needed that day for those present. By being nondenominational we are being all inclusive.
So the answer to the question, what type of healing energy is used, is whatever you need today.
