In magick, we use ourinner energy, combined with earthly andelemental energy and Deity energy, and send this forth do accomplish the goal of our spell. I feel that aprayer works the opposite way. Now I'll try and tie in Parapsychology. It's just on a different 'frequency'. Grounding negative feelings is an example of converting one form to the other.
Auric healing is the opposite.
So, I feel the energies are inter-changeable. As someone stated before, the definitions we are trying to define and clarify are our own, much like our beliefs- our own. We are trying to find, I believe, common ground between the nuances of our definitions and beliefs.
