Limiting Adjunct (Upādhi)

An upādhi is a 'limiting adjunct' — something that, by its mere proximity, makes the unlimited appear limited, the way a colorless crystal seems to turn red when set beside a red flower, without actually changing. Advaita uses the idea to explain its great puzzle: if there is only one infinite self, why does it appear as countless separate individuals? Because, the answer runs, the one consciousness seems divided and confined by adjuncts — the body and mind — that are not truly part of it. Remove the apparent limitation, and the boundless self stands revealed.
