大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 1.28

1.28

Furthermore, Lord of Mysteries, because of pity for boundless realms of beings this is in a broad sense the maṇḍala ‘Born of the Matrix of Great Compassion.’

“Lord of Mysteries, [the maṇḍala] is empowered by the anuttarā samyaksaṃbodhi accumulated by the Tathāgata during immeasurable eons, and therefore it is endowed with immeasurable virtues. You should understand as follows, Lord of Mysteries: it was not for the sake of one being that the Tathāgata attained perfect and full awakening, nor was it for two nor for many [beings]; it was out of pity for the realms of beings with complete predictions and incomplete predictions [of their future awakening] that the Tathāgata attained perfect and full awakening, and by the power of his vow of great compassion he expounds the Dharma in immeasurable realms of beings in accordance with their own nature.

“Lord of Mysteries, those who have not practiced the Great Vehicle in the past and have never thought about the practices of the Mantra Vehicle

are unable in the slightest degree to see or hear them, rejoice in them, and accept them on faith. But, Vajrasattva, if those sentient beings have in the past advanced through the immeasurable gateways of the path of the Mantra Vehicle of the Great Vehicle and have already been practicing it, it is for them that terms and numbers have been established within these [abovementioned] limits.

“The ācārya, too, should with thoughts of great compassion make the following vow: to receive immeasurable beings and create the causes and conditions for the seeds of bodhi so as to deliver [all] realms of beings without exception.

The mantra-reciting practitioner, having received [the disciples]

in this manner,

Commands them to take the Three Refuges, makes them confess

their previous sins,

Gives them unguent, flowers, and so on to offer to the holy deities,

And should confer upon them the precept of knowledge unobstructed

throughout the three ages.

Next, he should give them tooth sticks, of either uḍumbara

Or aśvattha and so on, protected [with a mantra], purified,

Adorned with perfume and flowers, straight, and conforming with

[distinctions between] top and bottom.

[The disciples] face either east or north, and having chewed [the

sticks], they cast them down—

[Thereby the ācārya] will know the signs of whether these beings

are suitable as receptacles or not.

A sūtra (cord) with three knots is then tied to their left arms.

In order that the disciples thus accepted may be freed from defilements

And increase their faith, [the ācārya] should expound the Dharma

accordingly

And encourage them, making their resolution firm, by proclaiming

these verses:

‘You will obtain an unequaled boon, your position identical to that

of the Great Selves.

All the Tathāgatas and the multitudes of bodhisattvas in this teaching

Have all received you, and you will accomplish the great deed

(i.e., enlightenment).
