佛頂尊勝陀羅尼經教跡義記 2.19

2.19

唐云世尊也。解曰：世尊者，具足稱言六種義自在熾盛與端嚴等。又薄伽云破。嚩帝云人。如人接戰，善解軍謀，對敵無遺，故云能破。是故降伏四魔，具大勢力，坐菩提樹，名婆誐縛帝也。

In Chinese, [buddhāya] means “World-Honoured One.” Explanation: “World-Honoured One” is fully endowed with six meanings, such as autonomy, brilliance, dignity, and so on. Furthermore, bhaga means “destroying,” and vate means “person.” Just like a person engaging in battle, who understands military strategy well and leaves no enemy undefeated, he is called “able to destroy.” Therefore, having subdued the four māras, possessed of great power, and seated under the bodhi tree, he is named bhagavate.
