Jnanaprasthana

Jñānaprasthāna or Jñānaprasthāna-śāstra, composed originally in Sanskrit by Kātyāyanīputra, is one of the seven Sarvastivada Abhidharma Buddhist scriptures. Jñānaprasthāna means "establishment of knowledge"

The Jñānaprasthāna was translated from Sanskrit 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 Aṣṭaskandha-śāstra in the Taisho, with the translation by Saṅghadeva, 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 Sarvāstivāda.

The tradition of the Mahāvibhāṣa states that it was taught by the Buddha himself, but differs as to the circumstances. It was later Kātyayanīputra who was responsible for the compilation thereof. The Mahā-prajñā-pāramitopadeśa (which actually refers to the Aṣṭaskandha) 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. 100 BCE.

The orthodox Vibhāṣa takes this as the ‘root’ Abhidharma, though references are sometimes made to the 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.
