To the pursuit of the intangible essence of yugen (幽玄)—yu (“profound” and “tranquil”) and gen (“mysterious”).
Yūgen suggests that which is beyond what can be said, but it is not an allusion to another world. It is about this world, this experience. All of these are portals to yūgen:
“To watch the sun sink behind a flower clad hill.
To wander on in a huge forest without thought of return. To stand upon the shore and gaze after a boat that disappears behind distant islands. To contemplate the flight of wild geese seen and lost among the clouds.
And, subtle shadows of bamboo on bamboo.”
