佛頂尊勝陀羅尼經教跡義記 2.15

2.15

唐言最殊勝也。解曰：三賢十聖分位修因，德行未圓不名最勝，唯佛上上無比特尊，因果具圓故名最殊勝。

In Chinese, [lokya-] means “most supreme.” Explanation: The three grades of worthy ones and the ten stages of sages cultivate causes in their respective positions; since their virtuous conduct is not yet complete, they are not called “most supreme.” Only the Buddha is paramount, matchless, and uniquely honored; because cause and fruit are both perfected, he is named “most supreme.”
