骨瑣（蘇果反廣雅云瑣連也字書連環也案言骨瑣者菩薩身骨也佛本行集經云凡夫骨節纔得相柱一夫之力也菩薩節皆相鉤連如馬銜連瑣相似遂成就廣大那羅延力說文云瑣字從玉𧴪聲也𧴪音同上從小從貝經從巢非也）。

Chain of bones (骨瑣: [瑣 is] su + guo fan. The Guangya says: 瑣 means connected. The character dictionaries say: interlocking rings. Examining this, 'chain of bones' refers to the bodily bones of a bodhisattva. The Fo benxing ji jing says: 'The joints of ordinary beings barely support one another, having only the strength of an ordinary man. The joints of a bodhisattva are all hooked and linked together, resembling a horse's bit and interlocking chain, thereby accomplishing the vast strength of Nārāyaṇa.' The Shuowen jiezi says: the character 瑣 takes the jade signific and suo phonetic; 𧴪 has the same sound as above, and takes small (小) and cowrie (貝). In the sūtra it takes nest (巢), which is an error).
