大毘盧遮那成佛神變加持經 (Shubhakarasimha & Yixing 724) 6.57

6.57

Next, internal homa extinguishes karma and [re]birth.

Understanding one’s own manas (mind), one dissociates oneself

from form, sound, and so on.

The eyes, ears, nose, tongue, and body, as well as verbal and mental

action,

All arise entirely from the mind and depend upon the mind-king.

The eyes and so on, born of differentiation, as well as the objective

realms of form and so on,

Obstacles to wisdom unborn, the Wind-parched Fire is able to

extinguish. It burns away false differentiation and accomplishes the pure

bodhi-mind. This is called internal homa, and it has been taught for bodhisattvas.”

Chapter XXVIII

The Exposition of Deity Samādhi

Thereupon the vajradhara Lord of Mysteries said to the Buddha, “Worldhonored One, I beg you to explain the actual manifestation of the physical forms and awesome efficacy of the deities so as to make bodhisattvas cultivating bodhisattva practices via the gateway of mantras visualize their deity’s form in such a way that their deity’s body is identified with their own body and they will without any doubt obtain siddhi.”

When the vajradhara Lord of Mysteries had finished speaking thus, the Buddha addressed him, saying, “Excellent, excellent, Lord of Mysteries! It is excellent that you have asked me about this matter. Now then, listen attentively and apply your mind very carefully as I now explain.”

Vajrapāṇi said, “So be it, World-honored One. I am eager to listen.”

The Buddha said, “Lord of Mysteries, the deities have three kinds of bodies, namely, syllable (akṣara), seal (mudrā), and physical form (rūpa). The syllables are of two kinds, namely, sound and bodhi-mind. The seals are [also] of two kinds, namely, with form and without form. The deity’s body is also of two kinds, namely, pure and impure. The pure body, of realization, is dissociated from all characteristics, while the impure conceptualized body has a manifest form and various colors. The two kinds of deity-forms accomplish two kinds of deeds: on account of the conceptualized [body] one accomplishes siddhi with characteristics, and on account of the unconceptualized [body] there accordingly arises siddhi without characteristics.”

He then spoke these verses:

The Buddha has taught that on account of the conceptualized one

will desire to accomplish [siddhi] with characteristics,

And by abiding in the unconceptualized one will obtain siddhi

without characteristics.

Therefore, one should in every way abide in the non-conceptualized.

Chapter XXIX

The Exposition of Samādhi

without Characteristics

Next, the Bhagavān Vairocana addressed the vajradhara Lord of Mysteries, saying, “Lord of Mysteries, those bodhisattvas cultivating bodhisattva practices via the gateway of mantras who wish to accomplish samādhi without
