According to Osho, you still don’t trust because mistrust is a deep habit formed since childhood—reinforced by cold, contradictory experiences and taught as a survival strategy. The mind becomes mechanical: it throws away even real warmth when it appears. Trust is rare, a touchstone; only conscious awareness and meditation can interrupt the reflex of doubt and allow you to recognize and receive genuine love.
Your mind got used to doubting to stay safe, so it keeps tossing away real kindness until you wake up and stop the habit.
