What does contagious magic rely on to create effects?

Contagious magic is a concept in anthropology that is based on the idea that objects once in contact with a person or being continue to influence each other even after they are separated. This type of magic relies on the principle that physical connections carry an inherent power, meaning that once something has touched the person, it retains a connection to them. For example, a strand of hair, a nail clipping, or any object that has been closely associated with someone can be used for magical purposes, as it is believed to embody the essence of that person.

This principle of physical contact is fundamental to contagious magic, distinguishing it from other forms of magical practices. While ritualistic offerings, symbols and signs, and verbal incantations can play roles in various magical systems, the defining characteristic of contagious magic is its dependence on the physical link established by prior contact. This foundational idea illustrates how different cultures understand the relationships between objects, people, and the metaphysical world.
