An nkisi is a type of spiritual object used in the traditional beliefs of the Kongo people in Central Africa. These objects are often made from materials like wood, metal, and cloth, and are believed to hold spiritual power. Nkisi are used in various rituals for healing, protection, and to communicate with ancestors or spirits. Nkisi can be adorned with various items, such as nails or other objects, which symbolize the intentions or prayers of the user. Each nkisi is unique and is often created by a nganga, a spiritual healer or priest, who imbues it with specific powers to address particular needs or issues within the community.
