We usually, casually, normally take it for granted that when we are awake and are communicating, relating, conducting, thinking, acting, speaking with ourselves and with others - we are really awake and alert... It is not so... most of the time we are simply reacting. Meditation is a way to get yourself a bit more alert when you are awake - and so you can infer any benefits as to how being alert might relate to you. Alert not as in a stressful way or taxing your mind or body, ... but alert as in a relaxed or in a natural way..
