How fast are things vibrating? How many sensations arise and vanish each second? This is exactly what you are trying to experience, but some very general guidelines can provide faith that it can be done and perhaps point the way as well. Begin by assuming we are initially talking about one to ten times per second. This is not actually that fast. Try tapping five to ten times per second on a table or something. It might take two hands, but it's doable, isn't it? You could experience that, couldn't you? That's the spirit!
