There's a Japanese story of a man who had bought a beautiful new vase,
immaculate,
created by a master.
He wanted to show this piece to his friend after the tea ceremony.
But since the vase was so new and immaculate,
he was ashamed of presenting it to his friend like this.
So he took a brush and dipped it into gold varnish which is used to cover the glue in cracks and fissures in ceramics.
He drew a line that looked like a crack in the new vase.
Now it was looking old and mended, not perfect any more.
