A Nahual is a concept from Mesoamerican cultures, particularly among the indigenous peoples of Mexico and Guatemala. It refers to a person who has the ability to transform into an animal or possess animal characteristics. This transformation is often believed to be linked to spiritual powers and is associated with the natural world. In many traditions, a Nahual is seen as a protector or guide, often connected to the individual's birth date or personal spirit. The idea of a Nahual is deeply rooted in Aztec and Mayan mythology, where these beings play significant roles in folklore and cultural practices.
