大方廣佛華嚴經疏 28.24

28.24

十七施象馬二事，合有十願：一如性調順；二如隨意所往；三似彼盛壯；四如超步萬里；五猶行步平正；六如彼象寶；七似彼如華；八即迅疾如風；九上云調順通顯增於功德，今云具菩薩地名最勝調象馬，各有調義，故分二願；十似彼上立金幢。

Seventeen: On giving the two things of elephants and horses. Together there are ten vows: (1) like their nature being tame and docile; (2) like going wherever one wishes; (3) resembling their flourishing strength; (4) like striding ten thousand leagues; (5) like their pace being even and upright; (6) like that elephant-jewel; (7) resembling being like a lotus flower; (8) being as swift as the wind; (9) above it was said that docility universally displays an increase in merit, whereas here it says possessing the bodhisattva stages is called the most supreme taming of elephants and horses—each has the meaning of taming, and so they are divided into two vows; (10) resembling setting up a golden banner upon them.
