The Bell is another ritual tool that is often found on the Altar. The Bell is used to mark the beginning and the ending of a spell.
The Bell is associated with the element of air and is a feminine symbol. For this reason it is also used by many practitioners to invoke the Goddess in ritual.
It can also be rung in an effort to ward off evil spirits and negative energies. It can be used to invoke good energies and be used as part of a spell to thwart a spell that is cast against you.
The Bell also has a protective function in so much that if you hang it on a door (or even put it in a cupboard) it will act as a guard and protect your home.
