仁王護國般若波羅蜜多經疏 3.546

3.546

解曰：言金剛利者，如彼經云，文殊師利菩薩也。依前法輪現勝妙身，正智圓滿，得自在故。手持金剛劍者，示其所作能斷自他俱生障故。依教令輪，現作威怒六足金剛，首臂各六，坐水牛上，摧伏一切諸惡毒龍，與惡風雨損有情者，令調伏故。放金色光者，顯能除遣惡龍等也。與彼西方廣目天王，及將無量諸龍、富單那眾而為眷屬，餘如文矣。從此第四北方菩薩。

Explanation: Regarding "Vajratīkṣṇa," as that sūtra says, this is the bodhisattva Mañjuśrī. In accordance with the previous wheel of Dharma, he manifests an exquisitely marvelous body, his correct wisdom being complete, because he has attained mastery. "Holding a vajra sword in his hand" illustrates that his activity can sever the innate obstacles of oneself and others. In accordance with the wheel of command, he manifests the wrathful Ṣaḍmukha Vajra (Yamāntaka), with six heads and six arms, riding on a water buffalo, subduing all the evil poisonous dragons who bring foul wind and rain to harm sentient beings, in order to tame them. "Radiating golden light" reveals his ability to banish the evil dragons and the like. He has the Heavenly King Virūpākṣa of the western direction, along with immeasurable hosts of nāgas and pūtanas, as his retinue. The rest is as in the text. Hereafter is the fourth part: the bodhisattva of the northern direction.
