In the previous posting, I wrote that the poetic-aesthetic experience created in the mind on reading a hokku is involuntary; it just happens, because the hokku has created the right conditions for it to happen.
To better understand this, let’s look at a famous old waka by Saigyō:
Even in the mind of a mindless one
When the snipe flies up from the marsh
In the autumn dusk.
By “mindless one,” Saigyō means a spiritual person who has calmed the mind through meditation. He thinks that even in such a person, given the experience of the autumn marsh, sadness must arise on seeing the bird rise up and fly away as day darkens. Such an experience is involuntary.
It is the combination of the season, the time of day, and the rising and flying off of the bird that creates this particular aesthetic sensation in the mind. Saigyō is saying that when the conditions are right, the experience will happen of itself in the mind — involuntarily. That is the principle of hokku.
Writing a good hokku means creating the right conditions for that experience to sprout in the mind.
Incidentally, I mentioned some time ago that hokku has an “evil twin” called senryu. While hokku is the verse of Nature and sensory experience, senryu, by contrast, is the verse of the quirks of human psychology and behavior. Where hokku creates a poetic experience in the mind, senryu creates a bitingly humorous glimpse into the worldly human mind, something quite different. We have already seen how Saigyō explained the rise of a poetic-aesthetic experience in his verse about the snipe. Now here is how senryu explains Saigyō:
And a verse about a snipe
It means that Saigyō, sitting in the marsh at evening, suddenly sneezed, which frightened a snipe, causing it to fly up and away, inspiring Saigyō to write his waka.
As you can see, unlike hokku, senryu tended to be witty and “low-class,” quite a different kind of verse. Even though the outward form is the same, senryu is about human psychology, not Nature, and unlike hokku, it does not have a required seasonal context.
