The Awakening of Mahāvairocana 3.19

3.19

爾時金剛手白佛言：「世尊！惟願復說此正等覺句悉地成就句。諸見此法善男子善女人等，心得歡喜、受安樂住、不害法界。何以故？世尊！法界者，一切如來、應、正等覺說名即不思議界。是故世尊！真言門修菩薩行諸菩薩得是通達法界不可分析破壞。」如是說已，世尊告執金剛祕密主言：「善哉善哉！祕密主！汝復善哉，能問如來如是義。汝當諦聽，善思念之，吾今演說。」祕密主言：「如是。世尊！願樂欲聞。」佛告祕密主：「以阿字門而作成就。若在僧所住處、若山窟中或於淨室，以阿字遍布一切支分時持三洛叉。次於滿月，盡其所有而以供養。乃至普賢菩薩、文殊師利、執金剛等或餘聖天現前，摩頂唱言：『善哉行者！應當稽首作禮，奉閼伽水。』即時得不忘菩提心三昧。又以如是身心輕安而誦習之，當得隨生心清淨、身清淨。置於耳上持之，當得耳根清淨。以阿字門作出入息，三時思惟，行者爾時能持壽命長劫住世。願囉闍等之所愛敬，即以訶字門作所應度者，授與鉢頭摩華，自持商佉而互相觀，即生歡喜。」

Then Vajrapāṇi said to the Buddha: "Lord, we pray that you once again speak these words of correct awakening, these words for the accomplishment of siddhi. When good sons and good daughters who see this Dharma rejoice in mind, experience a comfortable dwelling, and do not harm the dharmadhātu. Why is this? Lord, as for the dharmadhātu, all Tathāgatas, Arhats, and Samyaksaṃbuddhas describe it as the inconceivable realm. Therefore, Lord, bodhisattvas who cultivate the bodhisattva practice of the mantra-naya attain such penetration of the dharmadhātu, which cannot be analyzed or destroyed." After this was said, the Lord addressed the vajradhara, the Guhyakādhipati: "Excellent, excellent, Lord of Secrets! Excellent indeed that you can ask the Tathāgata about such a meaning! Listen attentively and reflect on it well; I will now expound it." The Guhyakādhipati said: "So be it, Lord. We wish and desire to hear." The Buddha said to the Lord of Secrets: "Accomplishment is made through the syllable A. Whether in a dwelling place of the Saṃgha, in a mountain cave, or in a clean room, when reciting three hundred thousand [times] while distributing the syllable A throughout all one's limbs; then on the full moon, make offerings with everything one possesses. Even Samantabhadra Bodhisattva, Mañjuśrī, the vajradharas, and so forth, or other holy devas, will appear before you, touch your head, and say: 'Excellent, practitioner! You should bow your head in homage and present arghya water.' Thereupon one attains the samādhi of never forgetting the bodhicitta. Moreover, reciting and practicing it with such lightness and ease of body and mind, one will attain purity of mind and purity of body corresponding to what arises. Placing it upon the ear and holding it, one will attain purity of the ear faculty. Performing inhaling and exhaling breaths through the gate of the syllable A, contemplating during the three periods, the practitioner can then maintain his lifespan and dwell in the world for long kalpas. If one wishes to be loved and revered by kings and the like, then through the gate of the syllable HA, regard those who should be saved, bestow upon them a padma flower, and holding a śaṅkha oneself, look at one another, and joy will immediately arise."
