"The purpose of meditation is personal transformation. The you that goes in one side of the meditation experience is not the same you that comes out the other side. It changes your character by a process of sensitization, by making you deeply aware of your own thoughts, words, and deeds. Your arrogance evaporates and your antagonism dries up. Your mind becomes still and calm. And your life smoothes out. Thus meditation properly performed prepares you to meet the ups and downs of existence. It reduces your tension, your fear, and your worry. Restlessness recedes and passion moderates. Things begin to fall into place and your life becomes a glide instead of a struggle. All of this happens through understanding."
