According to Osho, yes - real growth means knowing yourself less and less in the mind's terms: unlearning, becoming innocent and wonder-filled like a child. As borrowed knowledge evaporates, you are unburdened, free from mind, and your capacity to know turns inward. In this emptiness - 'I know nothing' - authentic self-knowledge dawns, bringing liberation, lightness, and a felt unity with the whole.
Stop trying to know everything with your head; become empty like a child, and true self-knowing naturally appears.
