Basho on writing haiku

Go to the pine if you want to learn about the pine, or to the bamboo if you want to learn about the bamboo. And in doing so, you must leave your subjective preoccupation with yourself. Otherwise you impose yourself on the object and you do not learn. Your poetry issues of its own accord when you and the object have become one - when you have plunged deep enough into the object to see something like a hidden glimmering there. However well-phrased your poetry may be, if your feeling is not natural - if the object and yourself are separate - then your poetry is not true poetry but merely your subjective counterfeit.
