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.

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

These are some of the characteristics of the state of mind which the creation and appreciation of haiku demand: Selflessness, Loneliness, Grateful Acceptance, Wordlessness, Non-intellectuality, Contradictoriness, Humor, Freedom, Non-morality, Simplicity, Materiality, Love, and Courage.

Thus we see that the all important thing is not killing or giving life, drinking or not drinking, living in the town or the country, being unlucky or lucky, winning or losing. It is how we win, how we lose, how we live or die, finally, how we choose.

The love of nature is religion, and that religion is poetry; these three things are one thing. This is the unspoken creed of haiku poets.

Mud is the most poetical thing in the world.

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.
