ABSTRACT
The JñAnaprasthAna, the last book of the Sarvastivada abhidharma, survives only in a Chinese translation and is the only text in both Northern and Southern abhidharmic traditions where the two nirvana theory was explained from the abhidharmic point of view. In fact we cannot find any explanation of the two nirvana theory in the seven books of the Pali abhidhamma. Most explanations we have are from their exegetical works.
