"As time moves on, the art of haikai will go through its own thousand transitions and ten thousand changes, but all transformations based on makoto (genuineness) will be part of the master's art. The master said, "Never content yourself with the drivel of the ancients. Just as the four seasons change, all things become new. Everything is that way."
-Tohō, disciple of Bashō (translated by David Landis Barnhill)
