Once a tradition commits to reality being fundamentally one, it owes an account of the many things everyone actually experiences: chairs, rivers, other people, this sentence. Indian philosophy developed two structurally opposed answers, known as parinama and vivarta, and the disagreement between them runs under several of the school-level debates covered later in this series.
Parinama holds that the transformation is real: the one substance genuinely becomes many things, the way milk genuinely becomes curd. Something happens, a real change with a real outcome, and the many things that result are actually there in the way the underlying substance was actually there. Samkhya philosophy takes this route for how prakriti unfolds into the observable world: a genuine, causally real unfolding, not an appearance laid over something unchanged.
Vivarta, the position Advaita Vedanta takes for Brahman specifically, denies that any real transformation occurs at all. The one reality only appears to become many, the way a rope only appears to become a snake in dim light: nothing in the rope actually changed, and no new entity, snake, came into existence. What changed was the perception laid over an unchanging basis. Brahman, on this account, does not turn into the world the way milk turns into curd. It appears as the world while remaining, in itself, entirely untouched by the appearance.
The stakes of the disagreement are high, because parinama and vivarta imply different fates for the individual self. If the world is a real transformation of the divine, the self that results is a real, if derivative, entity, and liberation looks like a further transformation. If the world is only an appearance laid over an unchanging Brahman, the self was never actually separate to begin with, and liberation is simply the correction of a mistaken perception, not a change of state. This same fork explains why consciousness itself, taken up next, is treated by Vedanta as something that cannot originate action, only illuminate it.
