大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 3.5

3.5

The well-abiding mantrin next recites for one month,

And in [this] preliminary expedient means the practitioner masters

each base. The buddhas of great renown have taught that this is the preliminary

recitation. Next, in accordance with what he has, he should offer up unguent,

flowers, and so on, And for the sake of accomplishing perfect awakening he redirects

[the merit thereof] to his own bodhi. In this manner within two months the mantra[-practitioner] will

become fearless. Then, having completed this [second] month, the practitioner

engages in recitation [proper]. A mountain peak or a cow pen, river sandbars, Crossroads, a chamber, a hallowed chamber, or the chamber of a

great god: The maṇḍala site is [made] completely like an adamantine palace, And having bound and protected the site, the practitioner performs

[rites of] accomplishment. In the middle of the night or when the sun rises The wise person should know that there may appear signs such as

these: A voice [saying] “Hūṃ,” or the sound of a drum, or again the shaking

of the earth, And he may hear words pleasing to the mind in empty space. He should know that with signs such as these siddhi will be all

as he wishes. The buddhas, honored among two-legged beings, have proclaimed

the result: If one dwells in this mantra practice, one will most certainly become

a buddha. One should in every way always keep the mantra in mind: Buddhas of yore, great seers, have taught [thus], and therefore one

should recollect it.

Chapter VI

The Manifestation of Siddhi

Thereupon the World-honored One again gazed upon the entire great assembly and, wishing to fulfill all wishes, again expounded Dharma-phrases for the consummation of knowledge determined by immeasurable gateways throughout the three ages.

Empty space is unsullied, without own-nature,

and bestows various kinds of skillful knowledge;

Because its own-nature is originally always empty,

it is dependently arisen, most profound, and difficult to see,

And in special progress over a long period of time

it grants the unsurpassed result as desired.

For example, just as dwellings in all destinies,

although dependent on empty space, are not attached to it,

So too is this pure Dharma like that,

and the three existences without exception are born pure.

Because the excellent-born, the imposing one, of yore cultivated this,

he acquired the conduct of all Tathāgatas.
