According to Osho, innocence cannot return to an adult without awareness. Only awareness dismantles the subtle hypnosis of social conditioning and borrowed beliefs that make us 'knowledgeable' but dead to wonder. By witnessing mind-chatter and knowing oneself, ideology falls away, and a fresh, childlike openness reappears—full of awe, presence, and freedom from robotic living.
Adults regain innocence by being aware and watching their minds until secondhand beliefs drop and life feels fresh again.
