角勝（上古岳反切韻角競也角觸也漢書故事云未夬庭設角抵戲者使角力相抵即今之相撲也經文從手作捔即掎捔非此用）。

Wrestling for victory [角勝] (The first character has the fanqie phonetic spelling 古 + 岳; the Qieyun says jiao means to compete, to lock horns; the Han History Precedents states: "When holding jiaodi contests at the court of the Weiyang Palace, wrestlers were made to pit strength against each other," which is today's sumo; the sūtra text writes it with the hand classifier as 捔, meaning flanking, which is not what is used here).
