佛祖統紀 39.62

39.62

述曰。夫呪以中道為體。持善遮惡為用。此大聖祕密化物之法。而持是法者必惟其人。故蘇婆呼童子等經云。諸呪皆有部主明王諸威德鬼神以為之護（部主如釋迦佛及觀音菩薩。明王即持明仙王。威德神即金剛神藥叉將。諸護呪神）然明王部主。慈悲覆護於彼呪師。不見其過。至於諸惡毒鬼。見有為利養詐解持誦者。見彼癡人繆執金剛杵。便生嗔怒。即害彼命（云云）。今觀西僧不知持善遮惡之義。而欲以區區呪術遠來東土呪死為功邀名人主。有利欲之心無沙門之行。是宜護呪鬼神乘怒以斃之耳。呪騎兵死。呪傅奕不死。奕小人謗法。罪在泥犁。非奕能拒呪也。此事至祕。唯探索呪部者能知之。佛舍利齒骨一切物不能壞。彼婆羅門所携之齒。恐非佛真。用羚角以碎之。或金剛石偽為之物。雖足以成傅奕博物之名而終不能知吾佛金剛不壞之體。世好黨奕而不知義故為辨之。庶幾乎免謗法之罪而救淪墜之苦也。

The commentary states: A dhāraṇī takes the Middle Way as its essence, and taking hold of good while warding off evil as its function. This is the great sage's secret method for transforming beings, yet one who upholds this method must truly be the right person. Hence sūtras such as the Subāhuparipṛcchā state that all mantras have section lords, vidyārājas, and awe-inspiring spirits and deities to protect them (section lords are like Śākyamuni Buddha and Avalokiteśvara Bodhisattva; vidyārājas are the kings of vidyā-holding immortals; awe-inspiring deities are vajra spirits and yakṣa generals, the deities who protect mantras). However, the vidyārājas and section lords compassionately shield and protect that mantra master and do not scrutinize his faults. But as for evil, venomous demons, when they see one who falsely pretends to understand and recite [the mantra] for the sake of material gain, or see that foolish person mistakenly grasping a vajra pestle, they give rise to wrath and take his life (and so forth). Looking now at the western monk: he did not understand the meaning of holding to good and warding off evil, yet wished, with petty incantations, to come from afar to the Eastern Land to count chanting people to death as an achievement and seek fame from the ruler of men. Having a mind of profit and desire but lacking the conduct of a monk, it was fitting that the deities protecting the mantra took advantage of their anger to slay him! He chanted the cavalrymen to death, but chanted Fu Yi and he did not die. Yi was a petty man who slandered the Dharma; his sin lies in Niraya (hell), but it was not that Yi could ward off the incantation. This matter is extremely secret; only those who explore the mantra collections can know it. The Buddha's relics, teeth, and bones cannot be destroyed by any object. That tooth carried by the brāhmaṇa was probably not genuine of the Buddha, and was smashed with an antelope horn, or it was an object counterfeited from diamond. Although it was sufficient to establish Fu Yi's reputation for erudition, he ultimately could not know the adamantine, indestructible essence of our Buddha. The world is fond of siding with Yi without knowing the principle, so I have clarified it, hoping to avoid the crime of slandering the Dharma and save people from the suffering of falling [into the lower realms].
