I second your view on this. I also agree with razvan...doing nothing is meditation. At least that is the way I meditate. If you view meditation as a chore, or something that you must 'fit into your schedule', then I see your point. But, that isn't the best way to view meditation in my opinion. For me, meditation is exactly what you describe. I sit, empty my mind, and do nothing. Sometimes it lasts an hour, sometimes 10 minutes. The truth is, it's difficult to tell because time doesn't seem to exist when the mind is in a meditative state. In any case, I like your suggestions, regardless of how it's defined.
