According to Osho, prati-prasav is unlearning itself: reliving past experiences consciously dissolves their imprints. When an event is fully re-experienced, it evaporates—its conditioning and emotional residue leave no marks, and the inner slate becomes clean. Thus, calling prati-prasav 'unlearning' is accurate; reliving is the very process by which learned patterns are undone and freedom arises.
Yes—it's like rewatching an old scene so completely that it erases itself, leaving your mind’s chalkboard clean.
