According to Osho, you cannot "bring" light into the unconscious; you can only prepare—relax into silence and love, let go of effort and expectation, and become empty. Then, suddenly, light descends by itself, flooding the unconscious like thousands of suns. The ego dissolves, the hunger for “more” ends, and a new, authentic being is born—this explosive illumination is enlightenment.
Stop trying to switch on an inner light; be quiet, open, and empty, and the light comes by itself and fills everything until the “me” fades.
