Drawing Three Thin Lines Up to the Length of the River

川の長さにまで至る、三行の薄いしるべを引く

To the left, there is the city, but to the right, the river flows. What is a river when your thoughts are more rapid than everything else? Two poets, Natsumi Aoyagi and Nobunari Mizushita, are having a back-and-forth kind of conversation and trying to get closer to the river. They exchange three-liner poems with each line written at such length and speed that it could stretch to the length of the river. Or not.
