仁王護國般若波羅蜜多經陀羅尼念誦儀軌 1.17

1.17

解曰：梵云藥叉，此云威德，又翻為盡，能盡諸怨故，如彼經云摧一切魔怨菩薩也。依前法輪，現勝妙身，事智圓滿得自在故。手持金剛鈴者，其音震擊覺悟有情，表以般若警群迷故。依教令輪，現作威怒淨身金剛，示現四臂，摧伏一切可畏藥叉，常於晝夜伺求方便奪人精氣害有情者，令調伏故。放瑠璃色光者，顯能除遣藥叉等也。與彼北方多聞天王及將無量藥叉眾、羅剎娑眾而為眷屬。與四俱胝菩薩往護其國。

The commentary states: In Sanskrit it is yakṣa; here translated as 'awesome virtue', and also translated as 'destroyer', because he can destroy all foes; as stated in that sūtra, he is Sarvamāropramardin Bodhisattva. In accordance with the aforementioned dharma wheel, he manifests an exceedingly wondrous body, having perfected action-wisdom and attained mastery. As for holding a vajra bell in his hand, its ringing sound awakens sentient beings, symbolizing the rousing of the deluded masses with prajñā. In accordance with the injunction wheel, he manifests as the awe-inspiring and wrathful Viśuddhadeha Vajra, displaying four arms, subduing all fearsome yakṣas who constantly seek an opportunity day and night to drain humans of their vitality and harm sentient beings, in order to tame them. Emitting vaidūrya-colored light signifies the ability to dispel yakṣas and the like. Accompanied by Vaiśravaṇa, Heavenly King of the northern direction, who leads immeasurable retinues of yakṣas and rākṣasas, he goes with four koṭis of bodhisattvas to protect that state.
