What worked for me: to start, sit or stand facing the tree, rock, plant, animal, person, statue--best to start with something that isn't going to walk away, of ask what you're doing. Reach as if to touch the object with the palms of your hands, but don't touch it. I find it best to close your eyes and to pay attention to what you feel through your hands. slowly move your hands toward and away from the object, still without touching it. Move your hands slowly up and down, around the object. All the while, still your mind, but you may also ask the object for permission to feel it. You may also do this between your open hands. I feel a very slight pressure, a resistance, on my hands as I do these things, as if feeling a slight push of wind, or a very soft fabric. Sometimes, almost like a static charge. If I move my hands too fast, or lose my concentration, the feeling goes away.
