“There is no poetry for the practical man. There is poetry only for the mankind of the man who spends a certain amount of his life turning the mechanical wheel. But let him spend too much of his life at the mechanics of practicality and either he must become something less than a man, or his very mechanical efficiency will become impaired by the frustrations stored up in his irrational human personality.
An ulcer, gentlemen, is an unkissed imagination taking its revenge for having been jilted. It is an unwritten poem, a neglected music, an unpainted water color, an undanced dance. It is a declaration from the mankind of the man that a clear spring of joy has not been tapped, and that it must break through, muddily, on its own.”
– John Ciardi
“Poems are not written to sing of the moon and flowers; they must speak of our hearts in response to the moon and flowers. We must never forget that in our hearts are the seeds of our poems. If we merely speak of the moon and flowers, poems become simply poetical forms, whatever the human heart may be. If these things become a part of ourselves, then we may admire them in verse.”
– Okuman Kotomichi

“A haiku . . . is a hand beckoning, a door half-opened, a mirror wiped clean. It is a way of returning to nature, to our moon nature, our cherry blossom nature, our falling leaf nature, in short, to our Buddha nature. It is a way in which the cold winter rain, the swallows of evening, even the very day in its hotness, and the length of the night become truly alive, share in our humanity, speak their own silent and expressive language.”
— R. H. Blyth, Haiku, Volume 1, page 243
