According to Osho, senility is growing old without growing up—age advances but maturity, integration, and inner ripeness never happen. As energy wanes, controls collapse and the long-repressed child resurfaces as childishness: foolish and reactive. This is not sacred child-likeness. True child-likeness flowers from a fully lived, mature life, returning to conscious innocence beyond knowledge, cunning, and games.
Senility means getting old but not wise, so when your strength fades your hidden immaturity pops out as childishness—not the clear innocence that comes from real inner growth.
