Dag Hammarskjöld said this quote
“ You are not the oil, you are not the air—merely the point of combustion, the flash-point where the light is born. You are merely the lens in the beam. You can only receive, give, and possess the light as the lens does. If you seek yourself, you rob the lens of its transparency. You will know life and be acknowledged by it according to your degree of transparency—your capacity, that is, to vanish as an end and remain purely as a means. ”
