In some parts of the country summer lingers. In others autumn has already come. Here is a hokku by Taigi, which expresses the transition from one to the other:
The summer shower becomes
A night of rain.
Taigi thought the sudden sprinkles of rain were just another brief summer shower; but when the rain persisted into the twilight and then the darkness of night, he realized that summer had ended, and autumn had come.
The harmony in this verse is in the rain persisting into the growing darkness, which is in keeping with the coming of autumn, the weakening of the Yang energies; it is also in the persistence of the rain, in which we sense the long and darker interval until spring comes again.
Taigi has another hokku relating to this time of year:
The weak feeling
After a bath.
In the first verse we saw the beginning of autumn in the continuing rain. In this verse we see it in the lack of physical energy after a warm bath. Ordinarily it would not be significant, but Taigi feels in it the weakening of all the energies of Nature, and realizes that his body is expressing the coming of autumn, just as in the rest of Nature the high energies of summer have have begun their long weakening first into autumn, and eventually into the deep Yin of winter.
