"Qatsi" is a term derived from the Hopi language, meaning "life" or "existence." It is most commonly associated with the film trilogy directed by Godfrey Reggio, which includes "Koyaanisqatsi," "Powaqqatsi," and "Naqoyqatsi." These films explore the relationship between humans, nature, and technology through stunning visuals and a powerful score by Philip Glass. The trilogy presents a critique of modern society, emphasizing the imbalance between natural and artificial environments. Each film uses a unique approach to storytelling, relying on imagery and music rather than dialogue, inviting viewers to reflect on the impact of human actions on the world.
