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.

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.

Any enlightenment which requires to be authenticated, certified, recognized, congratulated, is (as yet) a false, or at least incomplete one.

Regarding R. H. Blyth: Blyth's four volume Haiku became especially popular at this time [1950's] because his translations were based on the assumption that the haiku was the poetic expression of Zen. Not surprisingly, his books attracted the attention of the Beat school, most notably writers such as Allen Ginsberg, Gary Snyder and Jack Kerouac, all of whom had a prior interest in Zen.

Think of Zen, of the Void, of Good and Evil and you are bound hand and foot. Think only and entirely and completely of what you are doing at the moment and you are free as a bird.

Zen is poetry; poetry is Zen.
