a prayer wheel like this one was offered to H.E. Garchen Rinpochewith the drikung kagyu logo on it sitting on a lotus... it was made from two different hardwoods. the sphere made from African Walnut and the handle from Walnut. Rinpoche loved it and spun it all along the retreat in Israel. it has 400,000 White Tara mantras inside.
