Our intellectual capacity is limited; we cannot solve any of the final problems. Even Buddha never answered them. NAGARJUNA'S eightfold negations are that there is no becoming, no not being, no annihilation, no persistence, no unity, no diversity, no coming, and no departure. Even this path, says NAGARJUNA, is precarious and relative. There is no surety whether things exist or not, or both, or neither. Only void-ness exists because nothing is permanent.
Everything is in a process of change. What we call evolution also proceeds under the sign of decay. Consequently, there is nothing which exists truly as it manifests itself before us. The way things look are similar to a dream. The contingency is the true nature or form of being of the empirical reality. Unfortunately, the form under which this reality appears to us is only an illusion.
NAGARJUNA' says: Substance does not exist, non-substance also does not exist, nothing that is to be designated by words exists at all. All the things that are designated by words similar to 'NIRVAN' are void of an own being. Since the own being of all things is nowhere — neither in the conglomerate of causes and conditions, nor in each of them—all things are void of own being.
Something existent cannot be born, since it is already existent. So is the case with anything non-existent. What has already been born, cannot be produced, and what is not yet born cannot be produced.
If the effect existed, there would be a cause provided already with its effect. If that effect does not exist, the cause is similar to something nonexistent and it is contradictory that the effect be not existent at the same time than the cause. Therefore the cause is not logically possible in any of the three times...
Since an own being does not exist, how could things be 'a thing in itself' or 'another thing' or perish? Therefore 'another thing', 'nothing', 'thing in itself' are errors.
If things are void they are not destroyed, they are not born. Then how and when could 'destruction' be produced? If birth and cessation do not exist, through the cessation of what would 'NIRVAN' be produced?
If 'NIRVAN' is cessation, there is nihilism; if it is the other alternative, there is eternalism. Therefore it is neither an existing thing nor a non-existing thing, it is without birth and cessation.
Since birth, permanence and destruction — the three characteristics of conditioned things — do not exist, then, what is conditioned and what is not conditioned, do not exist. Since consciousness, which arises instantaneously, does not grasp the visible thing that is born also instantaneously, how could it perceive something visible already past or not yet arrived?
If one exists only 'within', the other ones are void. What is void does not lean upon what is not void, nor does what is not void lean upon what is void. With the cessation of the mental creations, which constitute the net of false doctrines, one becomes calm and moves towards void.
