This Buddhist Prayer Wheel is a hollow cylinder made of acrylic with antique copper finish and a wooden handle. The idea of spinning mantras originated from various Tantric practices where the mantras are visualized revolving around the "nadis" and meridian chakras such as brain and heart. Many Buddhists believe that prayer wheel is "Wheel of Law" that has been set in motion by The Buddha. This prayer wheel measures 7 inches long. The actual wheel measures about 2.5 inches high and 2.5 inches wide.
