According to Osho, knowledge is not absolutely useless: it is valuable for navigating the outer world—society, science, expertise—where information, technique, and tradition are needed and respected. But for the inner journey, knowledge turns into a barrier, feeding ego and secondhand beliefs. Inner exploration demands wisdom—your own lived transformation—born of humility and egolessness, not accumulated facts. Use knowledge as a bridge outside; drop it to go within.
Use facts to handle life outside, but to know your true self, let go of showing what you know and become humble, quiet, and aware.
