Prayer wheels are used to gather wisdom and good karma and to purify bad karma. It is a cylindrical wheel surrounded by a written mantra on a spindle, which can be made from various materials such as metal or wood. Usually the traditional Om Mani Padme Hum sanskrit symbols can be found around the outside.
Traditionally, spinning such a wheel is thought to have the same effect as orally reciting the mantra, however focusing the mind and repeating the mantra is more effective. Visualizing mantras revolving around the chakras, especially the crown and heart can be a powerful practice.
Prayer wheels are usually spun clockwise in a gentle rhythm while being mindful of the spirit of compassion.
These prayer wheels can be opened so that a chosen mantra may replace the one inside.
