大毘盧遮那成佛經疏 6.151

6.151

經云「爾時執金剛祕密主於一切眾會中，諦觀大日如來目不暫瞬」者，時佛如所示現普門漫荼羅，演說諸尊圖位竟。祕密主以普眼觀此一一諸尊，皆不見根本亦無住處，悉是蓮花臺藏實相之身，出生種種方便不可窮盡。爾時深自慶幸發希有心，倍於此法生難遭想。將欲更問深義，故先說偈也。初偈意言「一切智慧者，出興於世間，如彼靈瑞花，時時乃一現」耳。佛優曇花雖則難遇，然此真言法要倍復難遇之。何以故？此是如來祕藏，長夜守護不妄授人，苟無頓悟之機則不入其手。世尊在世猶多怨嫉，況末代乎。復次此經自釋難現因緣，若眾生一見此漫荼羅者，無始以來惡業重障摧滅無餘，必定得大菩提記，故非鈍根薄福之人所能遭也。一見尚難，何況次第修行？當知是人轉復希有，常為普門海會之所稱歎，名聞十方。又同大日如來有種種名號，故曰無量稱也。

When the sūtra says, 'At that time the vajra-holder Lord of Secrets, amidst all the assemblies, gazed intently at Vairocana Tathāgata without blinking,' the Buddha had just manifested the universal gateway maṇḍala and finished expounding the diagram and positions of the deities. The Lord of Secrets, viewing each and every one of these deities with his universal eye, saw neither root nor abiding place; all were the dharmatā-bodies of the lotus womb-treasury, generating various upāyas that can never be exhausted. At that time, deeply rejoicing and giving rise to a rare mind, he regarded this Dharma as doubly difficult to encounter. Wishing to further ask about profound meanings, he spoke verses first. The intent of the first verse is: 'All wise ones appear in the world just like that auspicious marvelous flower, appearing only from time to time.' Although a Buddha or an udumbara flower is difficult to meet, this essential Dharma of mantras is doubly difficult to meet. Why is this? It is the secret treasury of the Tathāgata, guarded through the long night and not given away haphazardly; if one lacks the capacity for sudden awakening, it does not enter one's hands. Even when the Bhagavat was in the world there was still much resentment and jealousy, how much more so in the final age! Furthermore, this sūtra itself explains the reasons why it is difficult to appear: if sentient beings see this maṇḍala even once, their heavy obstacles of evil karma from beginningless time are completely destroyed without remainder, and they will definitely obtain the prediction of great bodhi; hence it cannot be encountered by persons of dull faculties and meager merit. If even a single glance is difficult, how much more so gradual practice? One should know that such a person is all the more rare, constantly praised by the vast assembly of the universal gateway, with their fame resounding throughout the ten directions. Moreover, sharing various titles with Vairocana Tathāgata, they are therefore said to have 'immeasurable renown.'
