Metanoia (psychology)
In psychology, metanoia (from the Greek word μετάνοια, metanoia, meaning “changing one's mind” or “repentance”) refers to a process of fundamental psychological transformation, often precipitated by crisis, breakdown, or existential conflict. It denotes a shift in an individual’s perception of self, others, or life itself—typically involving disintegration of an old identity followed by the emergence of a reorganized, more integrated self.
