DESTROYED ON THE LATHE OF HEAVEN

Those whom Heaven helps we call the Sons of Heaven. Those who would by learning attain to this seek for what they cannot learn. Those who would by effort attain to this, attempt what effort can never effect. Those who aim by reasoning to reach it reason where reasoning has no place. To know to stop where they cannot arrive by means of knowledge is the highest attainment.
Those who cannot do this will be destroyed on the lathe of Heaven.
[Chuang-Tzu, XXIII, 7]
