牀座（狀莊反廣雅云人之棲息安身之具也說文云身所安也從木爿聲也經文作床非也撿字書並無此床字也爿音情羊反）。

Couch and seat (牀座: [the first character is] zhuang-zhuang [fanqie]. The Guangya says: "An implement upon which people rest and settle their bodies." The Shuowen says: "That where the body is settled. It takes its semantic classifier from 木 'wood' and 爿 is the phonetic." In the sutra text it is written as 床, which is incorrect; consulting the character lexicons, none has this character 床. 爿 has the phonetic reading qing-yang [fanqie]).
