I'm not sure I'm giving Reiki, having never had any instruction in the subject, what I do I found myself when somebody close to me was in need. After meditating or at least clearing my mind and trying to find the energy I put my hands over the affected area, trying not to touch, and trying to visualise the energy, and opening the crown chakra. Not sure you want to hear this, but I'm much, much more effective if I'm been smoking hashish or marijuana.
Now if I've been effective my hands are cold afterwards, sometimes icy cold. It doesn't worry me, I feel no pain, and normally have very warm hands, and a strong metabolism.
But a sign that I'm going to be very effective is cold hands. Someone had told me this is absolutely wrong, energy is warmth, and cold has no place in that.
Anybody got anything to say about cold hands being a sign of effectiveness?
