According to Osho, the Buddha ordained unripe, worldly-minded people because initiation is medicine for the sick and fire that ripens raw fruit. Only those in need come; the already ripe require no initiation. Buddha sees not your past flaws but your future possibility—your capacity to become pure gold through discipline and presence—so he welcomes the unripe to transform.
Because the path is like a school and a hospital: people come raw and messy, and being with a buddha helps them grow and heal.
