Pravicaya is the Sanskrit term for discernment and refers to the ability to distinguish pure from impure, material from immaterial, etc...Abhidharma in the absolute sense: pure understanding
Understanding (prajna), is the discernment
of factors [dharmapravicaya].
By innate I imagine it is referring to it being a consequence of past effort. I assume this as it is talking about impure understanding and thus cannot be referring to some sort of internal stainless basis/quality.2b. [The Abhidharma] is also any understanding and the Treatise which
make one obtain stainless understanding.
...the impure (sasrava) understanding, whether it is
i. innate or natural or acquired at birth
ii-iv. derived from an effort, i.e., from listening, reflection, cultivation
We also clearly see here that prajna (unafflicted knowledge) is also based on personal effort and study
Thus studying the text...the Treatise also makes one obtain the pure understanding...
Okay. WTF? Is he saying that dependently arisen objects have inherent characteristics?Etymological explanation of dharma and abhi-dharma
[Etymologically,] dharma signifies: that which upholds or sustains (dharana) its own
characteristic or a particular inherent characteristic (svalaksana).
The Abhidharma is called abhi-dharma because it is directed...
1. toward the supreme factor [paramarthadharma], namely, Nirvana
2. toward the characteristics of the factors [dharmalaksana], namely, (i) the
particular inherent characteristics or specific characteristics [svalaksana]
and (ii) the common characteristics [samanyalaksana].
