This observation by writer Virginia Woolf seems a perfect description of any artist's creative response to aspects of the world that strike a particular chord:
A sight, an emotion, creates this wave in the mind, long before it makes words to fit it; and in writing (such is my present belief) one has to recapture this, and set this working (which has nothing apparently to do with words) and then, as it breaks and tumbles in the mind, it makes words to fit it.
