namaste, your comments about the energy in the hands reminded me of something, not relating to the left and right hand energy but something else. This is something that one can do, by themselves, asking God to channel healing energy thru them to heal themself.
One stands feet apart, arms outstretched towards the heavens - palms facing up towards the sky.
Yes the arms and hands are used as a way of conveying the energy outwards (or in your case inward) to others for healing. The healing energy is drawn into the body thru the medulla oblangata which is the 'mouth of God' spoken of in the Bible. This is the entry point into the body for cosmic energy which sustains this body battery. In this case we draw this energy into the medulla (which is at the back of our neck) and into our arms and hands and direct it to others while visualizing this healing energy going out to others.
Daya Mata has also added: "When you are affirming healing for others or yourself, visualize the tremendous force of God's healing power as a white Light surrounding you or the person for whom you are praying."
