Double Sense

Try a simple experiment. Touch something (e.g. your desk, your keyboard). Concentrate on how that thing feels. Really feel it. As you're doing that, pay attention to what you are looking at (e.g. your monitor, a blank wall). Really see it.

Now, while you're seeing and feeling, observe your thoughts.

Can you pay attention to both at the same time? Are you sure that you are sensing touch and sight simultaneously?

If you were successful, tell me how you did it and how you knew you did it.
