無一物

There's a 楽 bowl named so made by 長次郎（ちょうじろう）, which 利休 possibly designed the shape for.
弘忍（hong ren) (5th Chan patriarch) (601–674) looked for a successor, and asked his students to compose a poem. One student wrote: Our body is the Bodhi-tree / And our mind a mirror bright. / Carefully we clean them hour by hour / And let no dust alight.. This was good, but too technical, too correct. 大鑒惠能 (Dajian Huineng, or Japanese: だいかん　えのう）wrote the following reply, and thus became the 6th patriarch.
