The document discusses the history and use of meditation bells in Buddhism. Meditation bells originated in Asia in the 8th century AD and are rung at the beginning and end of silent meditation sessions. They are made of various metals which produce different tones when rung, helping Buddhists to relax and play an important role in their healing practices. While bells come in various colors, the colors have no specific meaning. Some historical bells contain inscriptions showing they were gifts to monasteries and the tradition continues worldwide today.
