Tibetan Bell 6" and Dorje used for meditation and awareness.

The purpose of the bell is to awaken you to the present moment.  You can hit the bell with a wooden mallet, or you can simply ring it.

The dorje is made out of metal (or crystal) and is in the shape of two ovals joined by a smaller ball, with a shaft running through them. Dorje means thunderbold in Tibetan.  It's also sometimes described as a diamond scepter and is a sacred symbol of wisdom. People luse it in meditation, holding it in one hand in a mudra position.  The bell and dorje together represent feminine (bell) and masculine (dorje). - Taken from Suren Shrestha's book How to Heal with Singing Bowls.
