Meditation is not concentration, it is not even an effort to silence the mind or drive out the crazy random bla bla of mind. This is where most people go wrong, like achieving many things and trying to control, you start to wrestle with your mind, control your thoughts! Then you lose the battle and give up. Meditation is to be an innocent child with awe with everything but not judging! Become aware of all that is life, watch, observe, and let the mind embrace you with quiet love and simple happiness.
