"By the river Piedra I sat down and wept. There is a legend that everything that falls into the waters of this river—leaves, insects, the feathers of birds—is transformed into the rocks that make the riverbed. If only I could tear out my heart and hurl it into the current, then my pain and longing would be over, and I could finally forget."
–By the river Piedra I sat down and wept (1994). Paulo Coelho
