99-104 on his discussion of the two truths:
To hold that the two levels of truth are separate aspects of a single essence is to accept that illusion is ultimate truth. 266 [55b]
This contradicts the following passage from a sutra of The Perfection of Sublime Knowing: For one who has actually awakened to manifest and complete buddhahood, any given phenomenon is neither true nor false…
Timeless awareness of meditative equipoise knows all phenomena to be like the vault of space, whereas timeless awareness of post-meditation knows all phenomena to be like illusions.
It is not the case that ultimate truth consists of sensory appearances that are devoid of true existence.
Taking ultimate truth as the object to be negated, if one applies an unqualified negation—that it is neither one nor many—the negation cannot be verified, any more than can the horns of a hare.
If one simply applies a qualified negation, the negation cannot be verified, any more than can relative truth.
One might use as one’s proof a special kind of qualified negation, stating, “Ultimate truth exists within the scope of one’s awareness, perceived as being free of one thing or many. ”
Then, however, there is a contradiction between these very facts—that ultimate truth exists within the scope of awareness and yet is free of being one thing or many in essence.
Thus, such a proof cannot be established and is therefore not logical.
It is neither reasonable nor logically consistent, for it has the following flaws: it would mean that ultimate truth is in no way different from what is valid on the relative level; it would imply that an object to be negated could be examined in similar ways from the viewpoint of both levels of truth; and it would make the Madhyamaka view inferior to that of the Chittamatra system. (3)
As for holding that the two levels of truth are substantially separate entities, we may quote from the sutra The Definitive Commentary on Enlightened Intent, which undermines this position through five lines of reasoning: This would mean that even though one had actual realization of ultimate truth, one would not attain nirvana, because what is relative would be conceived of as being apart from the ultimate. This would mean that ultimate truth—substantially separate from what is relative—would not be the actual nature of relative truth, just as a vase is not the actual nature of a blanket. [56a]
This would mean—because the two levels of truth would be substantially separate—that ultimate truth would not constitute the mere fact that what is relative cannot be established to exist in the slightest, just as the mere fact that a vase cannot be established to exist in the slightest does not constitute a blanket. This would mean that even at the point that nirvana was attained through realization of ultimate truth in one’s direct perception, there would still be all-consuming afflictive states, because what is relative is a frame of reference apart from that of ultimate truth. This would mean that there would be no contradiction in all consuming afflictive states and total enlightenment functioning simultaneously in the mind of a single person. (4)
Therefore, ultimate truth (a freedom from all conceptual elaboration) cannot be described either as some real entity other than relative truth or as one and the same as relative truth; their “separateness” is merely a matter of their identity being negated.
Third, as for the derivation of the terms involved, the Sanskrit term samvrti means “that which obscures, ” and the Tibetan equivalent is kun rdzob (falsifying everything). 270
This refers to confused consciousness that obscures what is authentic. In that there is a validity inherent in the scope of such consciousness, there is “truth”; this truth lies in the very fact that, in essence, all the phenomena that manifest in myriad ways (as forms and so forth) are similar to dream images.
The Sanskrit term paramartha means “the goal sought by those who strive for what is truly excellent, ” and the Tibetan equivalent is don dam pa (sacred, or highest, meaning). 271
This refers to consciousness as the awareness that is in essence an unconfused state of mind; furthermore, it is sacred because it is the most sublime level of magnificence. In that there is validity within the scope of the unconfused state of mind, there is “truth, ” suchness itself. [56b]
Fourth, as for the definitive enumeration of these levels of truth, one can ascertain a context that involves dualism, owing to the simple negation of anything transcending all of the dualistic frameworks (existence and nonexistence and so forth) that apply to forms and other objects of knowledge. 272
In the absence of a third alternative, the valid cognition that conceives in terms of dualities brings a certainty that there is a definitive enumeration—a pairing of what involves duality with what is beyond duality. This definitive enumeration is achieved by classifying the two aspects of this pairing as the two levels of truth. Fifth, the detailed analysis focuses on two topics: the ultimate and the relative levels of truth. As the sutra The Reunion o f Father and Son indicates: There are two levels of truth for those wise in the ways of the world. You should not just listen to others talking, but see these for yourself. They are the relative and ultimate levels; in no way is there a third level of truth. If we analyze relative truth, we find that it also has two aspects. There is what is erroneous on the relative level (what is apparent yet incapable of performing a function) and what is valid on the relative level (what is apparent and capable of performing a function). Delineating the Two Levels of Truth explains: Although these aspects appear to be similar, because of the ability or inability to perform functions there is what is valid or invalid; this constitutes the analysis of what is relative. 273
That is, what is valid on the relative level comprises phenomena such as forms and so forth that are endowed with four characteristics: they are capable of performing functions according to the way they manifest, they come about from causes, they cannot bear up under mental examination, and they manifest according to their respective types. 274
They “exist” in that they have the ability to perform a function. [57a]
What is erroneous on the relative level comprises those sensory appearances that manifest but are incapable of performing a function, such as the optical illusion of a hair falling across one’s field of vision or the appearance of a double moon. 2″3
The Svatantrikas hold that these erroneous sensory appearances can be distinguished from valid phenomena on the basis of their inability to perform a function. As for what is ultimate, this also has two aspects. There is a quantifiable aspect of the ultimate; this aspect entails the simple negation of production and so forth in any true sense, but other than that, it does not entail freedom from the conceptual elaboration of nonproduction. The unquantifiable aspect of the ultimate is a freedom from absolutely all elaboration such as production and nonproduction. 276
According to the same source: The negation of production and so forth is considered to concur with what is authentic; the term “ultimate” is applied to the subsiding of all conceptual elaboration, even that of nonproduction. 277
