>In my experience, meditation is a process of bringing your body and mind to a restful, mindful state, and then listening to the thoughts and sensations that your body and mind are feeding to you. Allowing yourself to explore and feel those sensations, before letting them go and returning to the restful state.

This is not a definition that can be clearly repeated. How do you know when the subject is "restful" enough and "mindful" enough? What differentiates the "rest" of meditation from other forms of rest? I totally respect that your definition is individual. There's nothing wrong with that. However the definition you have described to me is not really actionable for a scientific study.
