Meditation is a process whereby the mind is withdrawn from external thoughts and concentrated on a single object. This object may be a word, idea, point, process, image, or some combination of the above. When the mind is made calm, it can reflect upon itself and experience the truth of its own nature more clearly. This is called self-realization. This calmness also removes the waves of agitation which cut us off from each other and the universe. Thus, meditation helps us experience unity and harmony with the world we live in.
