Sympathetic magic is a belief system in which objects or actions can influence one another based on their similarities or connections. This concept is often divided into two types: homeopathic magic, where a small part represents a larger whole, and contagious magic, which relies on the idea that objects once in contact continue to influence each other. Practiced in various cultures, sympathetic magic is commonly seen in rituals and spells. For example, using a doll to represent a person in a spell is a form of homeopathic magic. This practice reflects the belief that manipulating the representation can affect the actual person.
