With the unseasonably hot weather here, my thoughts turn naturally to cool water.
There is a verse by Shiki that is rather awkward in English if translated too literally, but it comes out well if we just take the meaning, like this:
At the bridge,
The horse instead
Goes through the river.
The whole point of the verse depends on knowing that it is a summer verse; given that, we know why the horse prefers to walk through the water instead of taking the bridge.
And we feel a similar sensation in a hokku by Buson, again taking the overall meaning rather than being too literal:
Cooling his chisel
In the clear water —
A stone mason.
The same water that cools horses and humans cools a chisel. The heat of the chisel (made hot by friction in use) brings out the coolness of the water, just as did the horse who preferred the river to the bridge.
Stones at the bottom
Seem to be moving;
The clear water.
R. H. Blyth tells us that Sōseki should not have said “seem to be.” That is because hokku goes with what is seen, without thinking it through intellectually. When looked at through the water, the stones DO move. We need no lesson on light and refraction telling us that it is only an appearance. The moving of the stones is the perceived reality; that they “really” do not move is the reasoned reality — “thinking.”
We could re-write it like this:
The stones at the bottom
