According to Osho, the crying, shouting, laughing, and dancing of catharsis last roughly three weeks to three months—shorter if you practice intensely and correctly, even dropping the middle stages and moving straight from the first to the fourth. It ends when mental impurities are expelled. Full, uncompromising expression speeds it; holding back can stretch the process for years.
If you do the method totally, these intense reactions finish in weeks; if you hold back, they can drag on for months or even years.
