If you want to really know something you have to observe or experience it in person; if you claim to know something on the basis of hearsay, or on happening to see it in a book, you’ll be a laughingstock to those who really know.
Shelves full of books are all around me. Opening the different volumes I take a look, and find the pages covered with writings in unknown scripts – tadpole traces, bird feet markings, twisted branches. And in my dream I am able to read them all, to make sense of everything despite its difficulty.
