In Buddhism, the 8 symbols represent offerings the gods made to the Buddha after his enlightenment. It is believed that each of these symbols have powers to bring blessings. Symbolically, a dorje represents the 'thunderbolt of enlightenment.'
The hollow of the bell symbolizes the wisdom cognizing emptiness. The clapper represents the sound of emptiness. The eight lotus petals on the bell are the four mothers and four goddesses, and the vase represents the vase containing the nectar of accomplishment. Paired with the dorje, the bell represents wisdom. As wisdom and method are an undivided unity, so the dorje and bell are never parted or employed separately.
