Devices for prayer are used the world over to mark chants and devotions. Repeated prayer is a tradition central to all of the great world religions, including Catholic rosary, Eastern Orthodox prayer, Sufi dhikr, Pure Land Buddhism Nembutsu, Tibetan Buddhist and Hindu Japa meditation. Historically, prayer rings have been chosen for their inconspicuousness in the face of persecution and durability with repeated use.
जप — Japa rings originated in India and are used in the repetition of a mantra. Like a rosary or prayer beads, the Japa ring is a central tool of mindfulness practice and meditation. Geometric diamond shapes form the seven points of the ring; the seven centers of the body; the seven days of the week - the cycles of our lives. Japa may be performed while sitting in a meditation posture, performing other activities, or as part of formal worship.
