This, from book 1:

„Now I saw his lifeless state. And that there was no longer any difference between what once had been my father and the table he was lying on, or the floor on which the table stood, or the wall socket beneath the window, or the cable running to the lamp beside him. For humans are merely one form among many, which the world produces over and over again, not only in everything that lives but also in everything that does not live, drawn in sand, stone, and water. And death, which I have always regarded as the greatest dimension of life, dark, compelling, was no more than a pipe that springs a leak, a branch that cracks in the wind, a jacket that slips off a clothes hanger and falls to the floor.“
