The vajra bell and pestle were introduced to China as early as the Tang Dynasty. The Tang Dynasty literature records that the "tantric masters who came to China from India are not free to leave to the Tang Dynasty (762-779) five vajra bell and pestle, silver plate, bodhi seed, and crystal. Count the beads.” In addition, the image of the vajra pestle also appeared in the Buddhist prints of the Tang Dynasty. With the spread of Tantric Buddhism (Tang Mi) in the Han Dynasty, the Vajra Bell and Pestle were also spread in the Tang Dynasty. The vajra also is a literal ritual object associated with Tibetan Buddhism, also called by its Tibetan name, Dorje. It is always sold in pairs with Dorje and placed on an altar.
