One may then ask: ‘Are not statements of how bodhisattvas, practicing the perfection of great intelligence, and thus seeing the reality of interdependent origination, recounted in such sutras as the noble Perfection of Intelligence (prajñāpāramitā) and the noble Ten Grounds (daśabhūmika)? Would it not then suffice to explain by quoting from such scriptures?’
This will also not do, because it is hard to ascertain their intent. One such as myself is not able to teach the actual reality from scriptures, or based on my own independent judgement explain what is stated there. But, by utilising treatises written by trustworthy individuals containing their infallible explanations, the intent of the scriptures may be ascertained:
As he was one who reached the deepest dharmic truths
Relying on the scriptures and through reasoning,
By following the system of Nāgārjuna,
As found within his works, I shall proceed to speak. (6.3)
Just like a bodhisattva practicing the perfection of great intelligence sees the nature of dharmas just as it is, the noble Nāgārjuna had an unmistaken understanding of the scriptures, and through the reasoning and scriptural citations in his Middle Way Treatise he explained in lucid detail how all dharmas are in actuality without any intrinsic nature (niḥsvabhāva). Thus, just as the noble Nāgārjuna explained the actual reality of all dharmas using reasoning and scripture, what I shall now say will be in accord with his manner of instruction.
