Regarding R. H. Blyth: The first book in English based on the saijiki is R. H. Blyth's Haiku, published in four volumes from 1949 to 1952. After the first, background volume, the remaining three consist of a collection of Japanese haiku with translations, all organized by season, and within the seasons by traditional categories and about three hundred seasonal topics.

Nothing divides one so much as thought.

There is no greater difference between men than between grateful and ungrateful people.

Things have done their part; it is for us to do ours.

Zen is mind-less activity, that is, Mind-ful activity, and it may often be advisable to emphasize the mind, and say, Take care of the thoughts and the actions will take care of themselves.

Regarding R. H. Blyth: Two men who may be called pillars of the Western haiku movement, Harold G. Henderson and R. H. Blyth. . . .

It is not merely the brevity by which the haiku isolates a particular group of phenomena from all the rest; nor its suggestiveness, through which it reveals a whole world of experience. It is not only in its remarkable use of the season word, by which it gives us a feeling of a quarter of the year; nor its faint all-pervading humour. Its peculiar quality is its self-effacing, self-annihilative nature, by which it enables us, more than any other form of literature, to grasp the thing-in-itself.
