Jnanaprasthana

Jnanaprasthana or Jnanaprasthana-sastra, composed by Katyayaniputra is one of the seven Sarvastivada Abhidharma Buddhist scriptures. Jnanaprasthana means "establishment of knowledge"

Jnanaprasthana was translated into Chinese by Xuanzang, T26, No. 1544, 阿毘達磨發智論, 尊者迦多衍尼子造, 三藏法師玄奘奉　詔譯, in 20 fascicles. It also appears under the name Astaskandha-sastra in the Taisho, with the translation by Samghadeva, Zhu-fo—nian and Dharmapriya: T26, No. 1543 阿毘曇八犍度論, 迦旃延子造, 符秦罽賓三藏僧伽提婆, 共竺佛念譯, in a slightly larger 30 fascicles. There is a slight difference in format of the two, perhaps indicating that they are different recensions from various sub-schools of the Sarvastivada [See Willemen, Dessein & Cox: Sarvāstivāda Buddhist Scholasticism, Brill, 1998. pg. 155~158, for more on this debate.] .

The tradition of the Mahavibhasa states that it was taught by the Buddha himself, but differs as to the circumstances. It was later Katyayaniputra who was responsible for the compilation thereof. The Maha-prajna-paramitopadesa (which actually refers to the Astaskandha) states that 100 years after the Buddha's demise, there arose doctrinal disputes among the great masters, giving rise to distinctly named schools.

Xuanzang maintained that it was written some three centuries after the Buddha, which would be c. 150 BCE.

The orthodox IAST|Vibhāṣa takes this as the ‘root’ Abhidharma, though references are sometimes made to the IAST|Prakaraṇapāda in the same terms. It became known as the ‘body’ of the Abhidharma, with the six remaining texts of the early period known as the ‘legs’ or ‘supports’. This is based on textual authority, and not a temporal definition, given the respective historical order of these seven treatises. That is, the Jñānaprasthāna is not sourced from the six legs, but neither is it directly sourced from the sūtras. This is also a reminder that these texts were all probably in a state of constant revision and update, for possibly several hundred years. There are thus mutual reference and borrowing of format and content, that cannot be summarily described by a simply sequential order [Mahāprajñāpāramitopadeśa: T25n1509_p0070a06] .

The outline of the text more closely approximates that earliest of models, the Sariputra Abhidharma, than those specifically Sarvastivada treatises. This is evidenced in its use of the samyojanas, prajna, karma, indriya, mahabhuta, dhyana and drsti as main divisions. A similar system is later continued through into the Kosa, and Hrdaya texts. Prior to this is a division of "assorted issues". The analysis is of three main types, according to Yinshun [Venerable Yinshun: Study of the Abhidharma, Texts and Commentators of the Sarvāstivāda, (說一切有部為主的論書與論師之研究), Zhengwen Publishing, 1968. pg. 184.] :
# Analysis of the sutras themselves – in order to find the actual underlying principle, rather than acceptance of the content at face value, which could lead to apparent contradiction. This indicates the Abhidharmika standpoint of taking the Abhidharma as pramana in understanding the doctrine.
# Analysis of the nature, or characteristics, of individual dharmas. Rather than the use of sūtra categories pertaining to spiritual praxis, the tendency here is to group by type. Thus, dharmas are assigned as either rūpa, citta, caitasika or citta-viprayukta – the conditioned dharmas, and also the unconditioned dharmas. Specifics as to each type are given, as well as detailed discussions of related dharmas. These are then again categorized according to their being with or without outflows; visible or non-visible; past, present or future; as to realm; and so forth.
# Analysis of the relationship between various dharmas. As the preceding analysis lends itself to plurality, and the possibility of falling into independent IAST|Saṃkhya-type realities, this analysis completes the Buddhist teaching of dependent origination, preventing such an error. Using IAST|kṣanika theory, it establishes the six-fold conditionality theory, that would later be a special feature of the Sarvāstivāda [Jnanaprasthana Sastra: T26n1544_p0920c06] . This is the earliest text in which the theory appears. It also includes some detail on citta-viprayukta-dharmas.

The influence of the Vijnanaprasthana is seen strongly in the Vibhasa, and this influenced the subsequent Hrdaya texts, and also the Kosa and commentaries.
