Pariṇāma-vāda, the doctrine of real transformation, holds that the cause truly changes into the effect. Sāṃkhya teaches that the world is a real transformation of primordial matter; some Vedānta schools that it is a real transformation of Brahman’s power. Advaita replaces it with vivarta, apparent transformation.
Pariṇāma
Real transformation: the view that an effect is a genuine change in its cause, as milk becomes curd.
