大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 3.28

3.28

And recites for a full month, one will obtain purity of hearing.

“Lord of Mysteries, these are the states of siddhi born of the mind. Lord

of Mysteries, when one visualizes [these letters], various and sundry kinds

of formations (saṃskāra) are born in an instant of thought from that which

has neither shape nor form, and by merely reciting them one is able to pro-

duce the seeds of all wholesome actions such as these.

“Furthermore, Lord of Mysteries, there is nothing that the Tathāgata

does not do. For bodhisattvas cultivating [bodhisattva] practices via the gate-

way of mantras he is like a reflection: he adapts to all places, adapts to the

minds of all beings, appears before them all, and causes all beings to obtain

joy. It is all because the Tathāgata has no differentiating mind and has dis-

sociated himself from objective realms.”

Then [Vairocana] spoke these verses:

Although [the Tathāgata] is beyond time, direction, and activity,

and is dissociated from what accords with the Dharma and what

does not accord with the Dharma, He is able to bestow the states of siddhi born of mantra practices. Therefore omniscience, the result of the Tathāgata’s siddhi, Is regarded as the state most revered, and [for this] one should

perform [rites of] accomplishment.

Chapter VII

The Accomplishing of Siddhi

Then the Auspicious Vajra[dhara] opened his eyes wide in wonder, In his hand he twirled a vajra seal, which scintillated like the light

of a fire, Its brilliance illuminating all buddha fields everywhere, And with sublime sounds he extolled the Muni, sovereign over

dharmas. “You teach mantra practices, but those practices are inapprehensible. From where do mantras come, and where do they go? May the buddhas explain this state beyond which there is none

higher, The goal to which all dharmas return, just as streams proceed to

the sea!”

When the vajradhara Lord of Mysteries had finished speaking thus, the World-honored One addressed him, saying:

Mahāsattva, the sense field of the mind is described as a maṇḍala, And when the station of mantras is understood to be in the heart,

one achieves their results. Everything that is differentiated is all born of the mind; The distinguishing of white, yellow, red, and the like arises from

the mind. A fixed mind when joyful is described as the inner locus of the heart; Mantras, located in that position, are able to bestow vast results. One thinks of a lotus flower there with eight petals and spread

with stamens;

On the flowery pedestal is the letter-gateway A, with a wreath of

flames and quite fine-looking,

Its radiance all-pervading so as to illumine beings. It is like the co-occurrence of one thousand flashes of lightning and

has the variegated forms of a buddha; [Like an image reflected] in a round mirror in a deep recess, it

manifests itself in all places, And it appears everywhere before beings like the moon [reflected]

in clear water. Knowing the nature of the mind to be like this, one succeeds in abiding

in mantra practices. Next, on top of one’s head where the parietal bones meet, One imagines the letter Aṃ, marked with a great dot of emptiness. Fine-looking, pure and unsullied, like crystal, the moon, or

lightning, It is described as the tranquil Dharma body (dharmakāya) and the

support of everything. [From it] the siddhis of mantras manifest different kinds of forms, And one obtains heavenly bliss and liberation and descries the state

of a Tathāgata. Making of one’s eyes the letter Ra, radiant like a bright lamp, One bends one’s neck, lowering one’s head slightly, and brings

the tongue close to the palate, And so one observes the locus of the mind: the mind will manifest

mental equipoise. It is always present [like] a round mirror, unsullied, wondrous,

and pure: Such has been proclaimed to be the true mind by buddhas of yore. When one has illuminated the path whereby the mind becomes

clear, material objects all emit light, And the mantrin will see the Perfectly Awakened One, honored

among two-legged beings: If he sees him, he will accomplish the foremost and everlasting

essence of siddhi. Next, he then imagines that he transforms this letter-gateway Ra, Placing the letter La with a great dot of emptiness (i.e., Laṃ) in the

position of his eyes.

Seeing the state of the emptiness of everything, he achieves the state

of immortality. If, desiring vast wisdom, or the exercise of the five supernatural

faculties, Longevity with a youthful body, the accomplishment of [the state

of] a vidyādhara, and so on, The mantrin has not yet achieved them, it is because he has not

followed this [procedure]. The wisdom generated by mantras is supreme real knowledge, The treasury of all buddhas and world-saving bodhisattvas, With which Perfectly Awakened Ones, world-saving bodhisattvas,
