Talisman

A talisman is any object ascribed with religious or magical powers intended to protect, heal, or harm individuals for whom they are made. Talismans are often portable objects carried on someone in a variety of ways, but can also be installed permanently in architecture. Talismans are closely linked with amulets, fulfilling many of the same roles, but a key difference is in their functions. An amulet protects a person or possession against evil forces while a talisman provides good fortune.

Talismans have been used in many civilizations throughout history, with connections to astrological, scientific, and religious practices; but the theory around preparation and use has changed in some cultures with more recent, new age, talismanic theory. Talismans are used for a wide array of functions, such as: the personal protection of the wearer, loved ones or belongings, aiding in fertility, and helping crop production. Provided by Wikipedia
