Amulet
An object worn or carried to keep something away, one of the oldest kinds of magick there is.
An amulet is an object that is worn or carried to keep something away: illness, envy, accident, bad dreams. The word comes from the Latin amuletum, which the Roman writer Pliny used in the first century for things that ward off harm.
Amulets are among the oldest things people have made. Egyptians wore the eye of Horus and the scarab, and laid them in graves with the dead. Roman boys were given a pendant called a bulla, which they took off on the day they came of age. In medieval Europe people wore written prayers, and small children wore coral. Every religion has its own: the cross and the saint's medal, the hamsa, the eye bead of the evil eye.
Modern witchcraft separates the amulet from the talisman: an amulet protects and keeps away, a talisman attracts. The two words have often been mixed up.
An amulet of your own can be anything small that means something to you: a key, a ring, a stone with a hole, a knot. It keeps something away from you and is aimed at nobody. Its effect is that it reminds you, each time you feel it, of the boundary you have set.
