Book Title: Parikshamukh Sutram (परीक्षामुखसूत्रम्) Author: Manikya Nandi (माणिक्य नन्दि) Commentary: Parikshamukh Laghuvrtti (परीक्षामुखलघुवृत्तिः) by Anantvirya (अनन्तवीर्य) Publisher: Asiatic Society, Calcutta (भारत की एशियाटिक सोसाइटी, कलकत्ता) Year of Publication: 1909 Editor: Mahamahopadhyaya Satishchandra Vidyabhusana (महामहोपाध्याय सतीशचन्द्र विद्याभूषण)

Overall Purpose: The Parikshamukh Sutram serves as an introduction (मुख - Mukha) to examination or inquiry (परीक्षा - Pariksha) into reality. Its aim is to establish the correct principles of knowledge (pramāṇa) and to refute false knowledge (pramāṇābhāsa), thereby guiding the reader towards understanding what is to be accepted (upādeya) and what is to be rejected (heya).

Structure of the Sutram: The Parikshamukh Sutram is divided into six chapters (uddēśa), each addressing a specific aspect of valid knowledge:

Pramāṇasvarūpoddēśa (प्रमाणस्वरूपोद्देशः) - The Characteristic of Valid Knowledge: This chapter defines what constitutes valid knowledge (pramāṇa). It is described as knowledge (jñāna) that is definitive (niścayātmaka) and pertains to a new (apūrva) object. The text explains that valid knowledge leads to the attainment of goals (hita) and avoidance of harm (ahita).
Pratyakṣoddēśa (प्रत्यक्षोद्देशः) - Direct Apprehension (Perception): This chapter deals with direct perception (pratyakṣa). It differentiates between different types of direct perception, including sensory and mental perception. "Visada" (विशद - clear or distinct) perception is highlighted as true direct perception.
Parokṣoddēśa (परोक्षोद्देशः) - Indirect Apprehension: This chapter covers indirect knowledge (parokṣa), which arises through mediate means. It categorizes indirect knowledge into:
- Smṛti (स्मृति): Memory, which is based on prior impressions.
- Pratyabhijñāna (प्रत्यभिज्ञान): Recognition, identifying something as the same or similar to what was perceived before.
- Tarka (तर्क): Reasoning or inference based on a hypothetical relation.
- Anumāna (अनुमान): Inference based on an established relation (vyāpti) between a middle term (hetu) and a major term (sādhya). The chapter elaborates on the structure of anumāna, including the five-membered syllogism (pratijñā, hetu, udāharaṇa, upanaya, nigamana), though it argues for the sufficiency of the hetu alone for the learned.
- Āgama (आगम): Testimony, particularly the teachings of omniscient beings (āpta).
Viṣayoddēśa (विषयसमुद्देशः) - The Object of Valid Knowledge: This chapter discusses the nature of the object of knowledge. It explains that the object of knowledge is characterized by both generality (sāmānya) and particularity (viśeṣa). Generality refers to the common characteristic shared by many instances, while particularity refers to the unique attributes of an individual entity. The text analyzes the concept of substance (dravya) and its transformations (paryāya).
Phaloddēśa (फलसमुद्देशः) - The Result of Valid Knowledge: This chapter describes the fruit or outcome of valid knowledge. The primary result is the removal of ignorance (ajñāna-nivṛtti). Other results include the ability to act in accordance with what is to be accepted or rejected (hāna, ādeya, upekṣā), leading to the ultimate goal of liberation. It clarifies whether this result is identical to or different from the knowledge itself.
Pramāṇādyābhāsasamuddeśa (प्रमाणाद्याभाससमुद्देशः) - The Semblances or Fallacies of Knowledge: This chapter critically examines various forms of false knowledge (pramāṇābhāsa), which appear like valid knowledge but are ultimately deceptive. It covers fallacies related to each type of knowledge:
- Pratyakṣābhāsa (प्रत्यक्षाभास): False perception (e.g., mistaking a rope for a snake).
- Parokṣābhāsa (परोक्षाभास): False indirect knowledge (e.g., faulty memory, incorrect recognition, invalid inference like "hetvābhāsa").
- Āgamābhāsa (आगमाभास): Untrustworthy testimony.
- Viṣayābhāsa (विषयाभास): False objects of knowledge (e.g., abstract concepts presented as independent realities).
- Phalābhāsa (फलाभास): False results of knowledge.

Key Concepts and Arguments:

Pramāṇa (Valid Knowledge): Defined as definitive knowledge of a new object. It is essential for distinguishing reality from unreality.
Types of Pramāṇa: The Jain tradition, as presented here, primarily recognizes two types of pramāṇa:
- Pratyakṣa (Direct Perception): Clear and immediate knowledge, not mediated by other senses or reasoning.
- Parokṣa (Indirect Knowledge): Knowledge acquired through mediate means, including memory, recognition, inference (anumāna), and testimony (āgama). The text discusses the role of tarka in inferential reasoning.
Anumāna (Inference): The text elaborates on the structure of inference, emphasizing the importance of vyāpti (invariable concomitance) between the middle term (hetu) and the major term (sādhya). It engages with different philosophical schools regarding the number of members required for a valid syllogism, ultimately advocating for the sufficiency of the core elements.
Āgama (Testimony): The validity of testimony is linked to the trustworthiness of the speaker (āpta), who is believed to possess perfect knowledge. The text discusses the nature of scripture and its relationship to valid knowledge.
Dravya and Paryāya (Substance and Modality): The text explores the Jain ontological framework, explaining that reality consists of substances (dravya) which undergo modifications or states (paryāya). It analyzes the interplay of generality (sāmānya) and particularity (viśeṣa) in understanding objects.
Fallacies (Ābhāsa): A significant portion of the work is dedicated to identifying and refuting various fallacies that distort or misrepresent reality, thus undermining valid knowledge. The text critically analyzes arguments from other philosophical schools (Bauddha, Mimāṁsaka, Sāṁkhya, etc.) to establish the validity of the Jain perspective.
Self-Validity (Svataḥprāmāṇya) vs. Other-Validity (Parataḥprāmāṇya): The commentary delves into the debate about how the validity of knowledge is established, discussing arguments for knowledge being inherently valid or dependent on external factors.

Commentary (Laghuvrtti): Anantvirya's commentary provides detailed explanations, clarifications, and refutations of opposing viewpoints. It often cites previous Jaina ācāryas like Akalanka Deva, whose work greatly influenced Manikya Nandi. The commentary aims to make the intricate logical arguments of the sutra accessible to students.

Historical Context: The introduction places Manikya Nandi around 800 A.D., noting his adherence to the Digambara sect and his engagement with various Indian philosophical systems. Anantvirya is placed around the time of Santi Sūri (died 1039 A.D.), making him a significant figure in Jain epistemology. The edition by Vidyabhusana is a valuable scholarly contribution, based on multiple manuscripts.

In essence, the Parikshamukh Sutram is a systematic treatise on Jain epistemology and logic, meticulously dissecting the nature of knowledge, its sources, its objects, its results, and the errors that can arise in the process of knowing.
