"This Absolute nature is neither one nor different; neither transient nor permanent. It has neither access nor egress and it can neither be created nor destroyed. It abandons all the four perimeters (fullness, void, both-fullness-and-void, and neither-fullness-nor-void). [In this way] the path-ways of words and speech are being abandoned. The unborn nature of the mind is the same. How can it be said that something is being created or extinguished; or that there is abidance or non-abidance?
"If [a person] says that the mind is capable of attainment, abidance, or perception, that means he has not attained anuttarasamyaksambodhi (complete, perfect enlightenment). [This] prajna (wisdom) is for those who are willing to abandon the 'long night' of the mind and its characteristics. Know that the mind is thus and its characteristics are also thus. This is non-creation and non-practice."
Cittaraja Bodhisattva noted, "Lord! If the mind is basically thus, nothing will be produced out of any practice. All practices, [therefore,] lead to nothing [Accordingly,] when one practises, it [ultimately] produces nothing. This non-production does not need to be practised. This is the practice of non-creation."
The Buddha asked, "Good man, you are employing [the practice of] non-creation [with the intention of] realizing the practice of non-creation."
Cittaraja Bodhisattva replied, "Not so. Why? Thusness (suchness) is beyond mind and practice. Both the nature and characteristics [of the mind] are void and calm, there is no [self-identification with] seeing or hearing, gain or loss, word or speech, perception, images, acceptance or rejection. How can there be any clinging or realization? If one clings to this realization, it amounts to disputation and contention [within the mind]. Only in the absence of disputation or contention lies the practice of non-creation.
The Buddha said, "Have you attained anuttarasamyaksambodhi?" [which cannot be attained or not attained]
Cittaraja Bodhisattva responded, "Lord! I am free from any attainment of anuttarasamyaksambodhi. Why is this? The nature of bodhi (awakening) has neither gain nor loss, enlightenment nor [ordinary] consciousness, for it is free from all characteristics of differentiation. Within this non-differentiation is the pure nature [of bodhi]. This nature is free from any extraneous admixture [such as the dualities of creation/extinction, subject/object]. It is free from words and speeches. It neither exists nor does not exist. It is neither aware nor unaware.
"This is also the same for all the dharmas (techniques) that can be practised. Why? Because all dharmas and practices have neither abidance nor abode. This is their Absolute nature. Basically, they are free from any attainment or non-attainment. So how can one attain anuttarasamyaksambodhi?"
The Buddha replied, "So it is, so it is. As you have said, all the activities of the mind are without form and its body (nature of the mind) is calm and non-creating. It is the same with all consciousnesses. Why is this? Know that the eyes and sight are both void and calm [by nature]. [Eye] consciousness [itself] is also void and calm - free from any characteristic of movement or stillness. Internally it is free of the three feelings (pleasant, unpleasant, or neutral). [Thus,] the three feelings are [already from the outset] calm and extinct. So are the hearing, smelling, tasting, touching, mental (sixth consciousness), discriminating (seventh consciousness), and alaya (eighth consciousness). All of them are also unborn.
[Therefore,] the mind is calm and extinct and non-creating. [If one tries to] create a calm, extinct and non-creating mind, it would be a practice that creates something; not the practice of non-creation. ... One does not cherish the realization of any characteristic of calm-extinction; nor does one dwell in non-realization. In non-abidance everywhere, lies the non-formation of all defilements. Thus, the three feelings, the three formations, and the three moral precepts will not arise. All [these] will be calm and extinct, pure and non-abiding. One does not [need to] access samadhi (mental absorption) or persist in dhyana (static mind-directed meditation). This is noncreation and non-practice."
