Meditation is a natural state of the human mindâat rest, open, alert. The basic meditation technique predates all religious traditions, though it is used in one way or another by each of them.

Objects of meditation can include the breath, an inner or external image, a movement pattern (as in tai chi or yoga), or a sound, word, or phrase that is repeated silently (mantra). The purpose of concentrative practices is to learn to focus one's attention or develop concentration.
