ABSTRACT
In one of his final works, Exposition of the Vajrasamadhi-Sutra (Kumgang Sammaegyong Non, translated as Book of Adamantine Absorption), 1 the great Korean commentator Wŏnhyo (617–686 CE) exhaustively outlines all the elements that go into human enlightenment. His work is far too complex for us to discuss here, but one of his lines of argument is directed towards the elimination of unproductive thought.
