According to Osho, such a question cannot be answered secondhand; the why of creation is meaningless without the living presence of a sincere seeker. God is not an idea gotten cheaply through borrowed curiosity; only intense, personal inquiry, with readiness to risk comfort and ego, opens the answer, conveyed more by presence than by words.
If you really want to know why God made the world, you must seek honestly yourself—the true answer comes through your own living inquiry, not from someone else’s explanation.
