According to Osho, accumulated knowledge is detrimental because it kills wonder - the childlike awe through which the divine mystery is known. Knowledge reduces life to explanations, feeds ego, and clutters the mirror-like heart, blocking surprise, poetry, and direct insight. He contrasts heady information with living "knowing," urging us to set concepts aside and meet existence freshly, as innocent eyes do.
When you think you already know, you stop being amazed, and without amazement you can't feel life's mystery or God, so drop explanations and look like a child again.
