From what I have experience thus far, energy transfer is a real thing but how the energy is transfered can be a touchy subject.
I think that we have two major areas where we end up talking about transference of energy.
As far as healing is concerned, I believe energy can be both transfered as well as received. You see this within the practice of reiki, qigong, accupuncture, etc.
Martial transference of energy is a far cry different than that of healing.
Within the martial aspect, energy is used to enpower the body and the intent, however, it is not expressed as glowing energy balls or things of the like manner.
