金光明最勝王經疏 3.7

3.7

贊曰：應身所化地上菩薩得弟子名。證平等理，故名一意。現一相者，但現佛相，無六趣別。所現佛身非無大小勝劣差別，十地位別，見有勝劣故。

Commentary: The bodhisattvas on the bhūmis transformed by the saṃbhogakāya receive the name 'disciples.' They realize the principle of sameness, and are therefore called of 'a single mind.' That it 'manifests a single mark' means that it manifests only Buddha marks, without the differences of the six destinies. The manifested Buddha-body is not without differences of magnitude, superiority, or inferiority, because the distinctions of the ten bhūmis lead to seeing differences of superiority and inferiority.
