Your objective is to attain total alertness, heightened sensitivity, and a full, unblocked experience of the motion of walking. Put all of your attention on the sensations coming from the feet and legs. Try to register as much information as possible about each foot as it moves. Dive into the pure sensation of walking, and notice every subtle nuance of the movement. Feel each individual muscle as it moves. Experience every tiny change in tactile sensation as the feet press against the floor, and then lift again.
