To understand music, you must listen to it. But so long as you are thinking, “I am listening to this music,” you are not listening. To understand joy or fear, you must be wholly and undividedly aware of it. So long as you are calling it names and saying, “I am happy,” or “I am afraid,” you are not being aware of it.
Words merely symbolise reality and are not reality, therefore trying to verbalise experience is counterproductive, as one should simply give into and experience the present regardless of its quality.
