According to Osho, you feel secure in conditionality because only illusions offer security; reality—life and love—is inherently insecure and unpredictable. The fearful mind trades aliveness for guarantees, building cages like legal, social and mental contracts (past/future stories) to avoid the risk of the present. This armor kills freedom. Real transformation begins by accepting insecurity and living authentically in the open sky of the present.
We cling to rules and promises because they feel safe, but life and love are wobbly; letting go of the cage lets you truly live now.
