金剛（金剛寶者最堅人剛以智諭焉金字說文云五色金也黃為之長久埋不生百鍊不輕從革不違西方之行生於土左右注二點象金在土中之形也從土今聲也剛字說文云強也從刀岡聲岡音同上從网下斷從山下文羅字亦從冈也）。

Diamond (金剛: the diamond jewel is the hardest of all; here it is used as a metaphor for wisdom; for the character 金, the Shuowen jiezi says: 'It refers to the five colored metals; yellow is the chief among them; buried long, it does not tarnish; refined a hundred times, it does not diminish; following change without resisting, it is the phase of the West; born from the earth, the two dots to the left and right represent the shape of gold within the earth; it takes its classifier from 土 "earth" with 今 as its phonetic'; for the character 剛, the Shuowen jiezi says: 'It means strong; it takes its classifier from 刀 "knife" with 岡 as its phonetic; 岡 has the same sound as above, taking 网 truncated below with 山 below; the character 羅 in the text below also takes 冈').
