Couches and daybeds [牀榻] (the upper character is chai + zhuang fan [chuang]. The Guangya says: 'An implement for resting and relaxing in peace.' The Shuowen jiezi says: 'Where the body finds repose; it takes the 'wood' radical and pan (pronounced qiang).' Written as 床 is a popular graph. The lower character is tu + da fan [ta]. A ta is also a bed. The Shiming says: 'A bed that is narrow and long is called a ta.' It has already been fully explained in the first fascicle of the previous sūtra.)
