Aloha SusanE,
"Feeling it," can be in various forms of feedback from just knowing, to seeing a shift in energy in the area, feeling a shift in physical sensation in the area, hearing, and even smelling a shift.
I'd recommend doing a little bouncing yourself, and the rubbing your hands warm before detecting and working on others, so you can help bring your focus to the hands you are detecting with. Then, state your intention and notice any shifts in sensation.
This will develop over time. At this point if you go through the steps in the manual and don't seem to notice anything , just trust and go until you sense it's done.
Much Love,
Shawn
