The besom, or broom, is used for sweeping a ceremonial area out before ritual. A light sweeping not only cleans the physical space, it also clears out negative energies that may have accumulated in the area since the last cleaning. The broom is a purifier, so it is connected to the element of Water. It is not uncommon to meet witches who have broom collections, and it is fairly easy to make your own besom if you don't wish to buy one. The traditional magical formula includes a bundle of birch twigs, a staff of ash or oak, and a binding made from willow wands.
