Dreaming Poetics 4: from Ryoshun's Gonjinshu

Man cannot exist without thought and words. Why then should it be difficult for him to express his thoughts with his mouth? If, for example, he thinks, “Brrr—how cold it is!” he will say, “I wish I had a jacket” or “I wish I could warm myself by a fire” and each of these is poetry.

From Ryoshun’s “Gonjinshu” quoted by Sasaki Nobutsuna in Nihon Kagaku Shi, p. 166, and in turn quoted in Donald Keene’s “Seeds in the Heart” p. 732
