大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 2.61

2.61

And cuts through them with the wisdom-sword seal: the cloud cover

will promptly disperse.

Alternatively the practitioner, with fearless mind, makes a kīlakam

(stake),

And he completely identifies this adamantine stake with a vajra.

Next, I shall now explain the quelling of all obstacles.

One thinks on the ferocious and very powerful Acala with his mantra

Dwelling in his own maṇḍala, or else the practitioner [himself]

dwells therein.

He visualizes an effigy [of the obstacle] with [Acala’s or his own]

left foot placed on its head:

The obstacle will be eliminated and extinguished, not to arise [again].

Alternatively, having carefully mixed [poison] with rājikā (black

mustard),

The practitioner makes an effigy [of the obstacle] and smears its

body with [the mixture]:

Those [obstacles] who seize one will, on account of this antidote,

Have their sense organs scorched—about this one must not engender

any doubting thoughts.

Even the honored ones Śakra and Brahmā, should they not follow

my teaching,

Will be burned, not to mention other beings.”

Thereupon Vajrapāṇi said to the Buddha, “World-honored One, insofar as I understand the meaning of what the Buddha has said, I too thus know that, dwelling in their own maṇḍala stations, the holy deities bring about what is awe-inspiring. Because they dwell in this manner, the Tathāgata’s injunctions cannot be obfuscated. Why? Because, World-honored One, the samaya of all mantras is to abide in their own lineage. Therefore, bodhisattvas cultivating bodhisattva practices via the gateway of mantras should also dwell in their proper station and perform [ritual] deeds.”

[The Bhagavān said, “Lord of Mysteries, it is so, it is as you have said.]40 Moreover, Lord of Mysteries, if colors have been mentioned [for any deities], you should know that the holy deities’ maṇḍala stations and the deities’ figures are also the same [colors]: this has been taught by previous buddhas.

“Lord of Mysteries, in future ages beings of inferior intelligence and no faith will, on hearing these explanations, be unable to accept them on faith because they have no intelligence, and their doubts will increase. If they merely hear them and remain set in their ways without practicing, they will harm themselves and harm others, and they will make statements such as ‘Non-Buddhists have such methods, but they were not taught by the Buddha.’ These ignorant people will produce such faith-and-understanding.”

Then the World-honored [One] spoke these verses:

The omniscient World-honored One has gained sovereignty over

dharmas,

And in accordance with what he has mastered, he delivers beings

by expedient means.

This was taught by previous buddhas to bring benefit to those who

seek the Dharma.
