Tapu is a concept in Māori culture that refers to something that is sacred or restricted. It signifies a state of being that is set apart and protected, often associated with spiritual significance. Items, places, or people deemed tapu are treated with great respect and care, as they are believed to hold spiritual power. In practice, tapu can apply to various aspects of life, including land, food, and rituals. When something is tapu, it may be forbidden to touch or use it without proper protocols. This concept helps maintain the balance and sanctity of the natural and spiritual worlds in Māori beliefs.
