“Where the mood of the moment is solitary and quiet it is called sabi. When the artist is feeling depressed or sad, and this particular feeling of emptiness catches a glimpse of something rather ordinary and unpretentious in its incredible "suchness," the mood is called wabi. When the moment evokes a much more intense, nostalgic sadness connected with autumn and the vanishing away of the world, it is called aware. And when the vision is hinting at an unknown never to be discovered, the mood is called yugen.”
