According to Osho, the “mysterious light” is your own eternal inner flame—the awareness always burning within. A powerful encounter turned your gaze back inward, revealing it. It isn’t an eye defect but new clarity; as your inner eye clears, that glow can become a sun. Turn attention inside, and the light is always available.
It’s the little lamp inside you; looking deeply made your eyes turn inward so you noticed it—your own light, not a defect.
