Rikyu was watching this son Shoan as he swept and watered the garden path, "Not clean enough," said Rikyu, when Shoan had finished his task, and bade him to try again.
After an hour the weary son returned to Rikyu: "Father, there is nothing more to be done. The steps have been washed for the third time, the stone lanterns and the trees are well sprinkled with water, moss and lichens are shining with a fresh verdure; not a twig, not a leaf have I left on the ground."
"Young fool," chided the tea master, "that is not the way a garden path should be swept." Saying this, Rikyu stepped into the garden, shook a tree and scattered over the garden gold and crimson leaves, scraps of the brocade of autumn!
What Rikyu demanded was not cleanliness alone, but the beautiful and the natural also.
