Humanity lost a great mind, but he will always be remembered, since he joined the ranks of immortals, as in the words of Rumi below.
I died as a mineral and became a plant, I died as plant and rose to animal, I died as animal and I was Man. Why should I fear? When was I less by dying? Yet once more I shall die as Man, to soar With angels blessed; but even from angel hood I must pass on: all except God doth perish. When I have sacrificed my angel-soul, I shall become what no mind e’er conceived. Oh, let me not exist! for Non-existence Proclaims in organ tones, To Him we shall return.
