**Prajnapanasutra Vishaya-Parichay**
Prajnapanasutra is the fourth Upanga and an Angabahya-Shruta of the Jain Agam literature. It contains 36 chapters. Here is a brief introduction to them:
The first chapter of Prajnapanasutra is called "Prajnapanam". It first explains the two types of Prajnapanam, then elaborates on Ajiva-Prajnapanam and then Jiva-Prajnapanam. Ajiva-Prajnapanam explains the different types of Ajiva, both Prarupi Ajiva and Rupi Ajiva. Jiva-Prajnapanam explains the two types of Jivas, Samsari and Siddha, and then elaborates on the 15 types of Siddhas and their differences based on time. It then explains the different types of Samsari Jivas. It classifies all Samsari Jivas from Ekendriya to Panchendriya based on the order of their senses. Here, the regulating principle of the differences in Jivas is the gradual increase in their senses.
The second chapter, "Sthanapad", describes the dwelling places of the following Jivas: Prithvikaaya, Apkaaya, Tejaskaaya, Vayukaaya, Vanaspatikaaya, Dwi-Indriya, Tri-Indriya, Chatur-Indriya, Panchendriya, Nairyaika, Tiryanch, Bhavanvaasi, Vyantar, Jyotishka, Vaimanika, and Siddha. There are two types of dwelling places for Jivas: (1) Svasthan, where a Jiva is born and lives until death, and (2) Prasangika Vasasthan (Uppaat and Samuddaat).
The third chapter, "Alp-Bahutvapad", considers the "alpaness" and "greatness" of Jivas in relation to 27 aspects: direction, motion, sense, body, yoga, Veda, kshaya, leshya, samyaktva, knowledge, vision, restraint, use, food, speaker, abandoned, sufficient, subtle, conscious, existence, Astikaaya, extreme, Jiva, field, bondage, pudgala, and Maha-Dandaka.
The fourth chapter, "Sthitipad", describes the state of the following Jivas: Nairyaika, Bhavanvaasi, Prithvikaaya, Apkaaya, Tejaskaaya, Vayukaaya, Vanaspatikaaya, Dwi-Tri-Chatur-Panchendriya, Manushya, Vyantar, Jyotishka, and Vaimanika.
The fifth chapter, "Visheshpad" or "Paryayapad", discusses the different types of Jivas from Nairyaika to Vaimanika Devas, in the order of the 24 Dandakas. It then discusses the different types of Ajova-Paryaya and the number of Paryayas in relation to the different types of Arupi Ajiva and Rupi Ajiva.
