Private religious devotion or mental exercise, in which techniques of concentration and contemplation are used to reach a heightened level of spiritual awareness. The practice has existed in all religions since ancient times. In Hinduism it has been systematized in the school of Yoga. One aspect of Yoga, dhyana (Sanskrit: “concentrated meditation”), gave rise to a school of its own among the Buddhists, becoming the basis of Zen. In many religions, meditation involves verbal or mental repetition of a single syllable, word, or text (e.g., a mantra). Visual images (e.g., a mandala) or mechanical devices such as prayer wheels or rosaries can be useful in focusing concentration. In the 20th century, movements such as Transcendental Meditation emerged to teach meditation techniques outside a religious context.

A movement that became popular in the West in the 1960s, it is based on specific meditation techniques and is not strictly connected with any religious tradition, though the perspective behind it has roots in Vedanta. Practice entails the mental repetition of a mantra in order to still the activity of thought and experience a deeper level of consciousness. Through this process, the practitioner finds deep relaxation, which can lead to inner joy, vitality, and creativity.
