'repairing of the world') is a concept in progressive Judaism, which refers to various forms of action intended to repair and improve the world. . In classical rabbinic literature, the phrase referred to legal enactments intended to preserve the social order. In the Aleinu prayer, it refers to the eradication of idolatry.
