He saw either death or the approach of it everywhere. But his undertaking now occupied him all the more. He had to live his life to the end, until death came. Darkness covered everything for him; but precisely because of this darkness he felt that his undertaking was the only guiding thread in this darkness, and he seized it and held on to it with all his remaining strength.
Leo Tolstoy, Anna Karenina
darkness, death, despair, dying
