A talisman is an object ritually cleansed and infused with energy intended to attract a specific positive force or energy such as to enhance health, increase wealth, to help in the achievement of a positive goal. Many also use the term talisman to defend against a negative force or other energy.
Today, the most common form of talisman is an object worn or carried on the body such as jewelry, a stone, a piece of glass or metal or other object.
Some use the term 'amulet' as a synonym for 'talisman'; but others use the term 'amulet' for the opposite purpose of a talisman- instead of attracting a specific force or other positive energy, a amulet can defend against a negative force or other energy.
A charm is a common term used by the general public for a talisman and an amulet.
