Toward Ecosophy

I'm trying the Healing Hands, and so far I never clearly "feel" anything no matter how long I leave my hands together or over an impaired body part. I'm not psychically perceptive in general. Should I fall back on imagining that I feel something, or just close it out on the assumption that something happened even if I can't feel it? Or assume that if I can't feel it, I can't do it? Thanks!
