**I. Overview and Authorship** "Ornament of Reason" (_’Thad pa’i rgyan_ in Tibetan) is a significant commentary on Nāgārjuna's _Root of the Middle Way_ (_Mulamadhyamakakarika_). It was composed by Mabja Jangchub Tsondrü. The work is explicitly intended to address the scarcity of commentaries elucidating the cultivation of mahāmudrā, the definitive meaning, and aims to dispel mistaken understandings while fostering certainty in practitioners. Mabja, also referred to as "Gampopa Mang-gala" in the source, began its composition at the isolated spiritual hermitage called Nāgakoṭa. The text is deemed beneficial for both those with and without meditation experience, including renunciates with extensive study but lacking direct experience. **II. Homage and Purpose of the Treatise** The "Ornament of Reason" begins with a homage to the noble youthful Mañjuśrī. It also pays homage to the "true teacher," the perfect Buddha, who reveals dependent origination as "this peace, the complete pacification of constructs". This homage implies physical, verbal, and mental veneration. Mabja explains that a treatise is generally endowed with four related elements, which serve to invite discerning and faithful followers of the Dharma: 1. **Special Purpose**: To avert the thought that the treatise serves no special purpose, like an investigation of crow teeth. 2. **Desirable Purpose**: To counter the idea that, even if there is a purpose, it might not be a desirable one (e.g., how to get married). 3. **Achievability**: To address the concern that the desirable purpose might not be achievable through this specific treatise (e.g., manufacturing a jewel ornament without obtaining the jewel itself). 4. **Relationship to Achievement**: To avert the thought that an easier way exists to accomplish the purpose without relying on this particular treatise. These four elements are implicitly stated in the praise to the Teacher, and the treatise's relationship to its purpose is implicit in its words. The "complete pacification of constructs" explains the subject matter, "who reveals this peace" shows its presentation, and "to the perfect Buddha" is the essential purpose. **III. Structure and Interpretation of Nāgārjuna's _Root of the Middle Way_** Mabja's commentary on Nāgārjuna's _Root of the Middle Way_ aims to clarify the Great Vehicle's principle of transcendent insight, resolving the essential meaning of the extensive, medium-length, and concise Mother Scriptures (Prajñāpāramitā sūtras). It is concerned with the natural emptiness of all phenomena, observed by insight. For each chapter of Nāgārjuna's text, Mabja generally follows a structure of (1) context, (2) explanation of content, and (3) a summary of its general significance. However, some chapters may not include a separate summary. **Key Concepts and Chapters Discussed:** - **The Title "Insight—The Stanzas of the Root of the Middle Way"**: - **"Middle Way" (_madhyama_)**: Signifies that which is beyond all extremes, including arising, ceasing, coming, going, annihilation, permanence, difference, and sameness. - **"Root" (_mūla_)**: Indicates that the full significance of the Middle Way is contained within this treatise. - **"Insight" (_prajñā_)**: Suggests that studying this text develops flawless insight into the two truths (conventional and ultimate), free from extremes of one-sided existence and nonexistence. - **"Stanzas" (_kārikā_)**: Denotes that the treatise is written in verse. - **Chapter 1: Analysis of Conditions**: This chapter focuses on the meaning that no phenomena arise by nature. It proves this by rationally refuting beliefs in real arising according to any of the four extreme ways, thus demonstrating that teachings on the absence of arising are of definitive meaning and are supported by reason. Conversely, teachings on arising and similar principles are presented as expedient meaning, concerned with what is false and relative. The _Noble Śālu Sprout Sūtra_ is cited to illustrate dependent arising, stating that a sprout is not created by itself or by something else, nor both, nor uncaused, nor by an almighty or time, but arises dependently. - **Chapter 3: Analysis of Faculties**: This relates to the teaching that visual consciousness arises based on the eye and form, and that the yogin perceives emptiness "like an illusion". - **Chapter 9: Analysis of Self**: This chapter uses reasoning to establish the complete nonexistence of any subject involved in doing or feeling. It aligns with sūtra teachings such as "Form is empty of I and mine" from _Mother of the Victorious Ones_ and the statement from _Journey to Laṅkā_ that "This so-called self is a demonic idea; From this, views issue forth. These conditioned aggregates are empty; Here, there is no self and no sentient being". - **Chapter 15: Analysis of Nature**: This chapter rejects the concept of "self-nature" (_svabhāva_), which implies an intrinsic, unconditioned, and permanent existence. It explains that "fabricated things" (composites) are described as having "other-nature" (_parabhāva_) in Abhidharma thought, as their being derives from their constituents. The text asserts that "While devoid of nature, it is feasible for fabrications to arise interdependently. For this reason, the categories of convention are indeed totally reasonable". - **Chapter 17: Karma**: Mabja presents a reasoning-supported account of karmic causality. An example of "nondissipation" is given, resembling a promissory note, where the action is the debt. **IV. Underlying Philosophical Tenets and Related Concepts** "Ornament of Reason" is deeply rooted in established Buddhist philosophical traditions and debates: - **Two Truths**: The treatise cultivates a flawless insight into both conventional and ultimate truths. Teachings on conventional truth include phenomena with qualities of arising and ceasing (e.g., self, life-force), while teachings on ultimate truth concern emptiness, the absence of a self, and nonarising. Provisional sūtras use terms like "self" even when no owner exists. - **Emptiness (_Śūnyatā_)**: For Mabja, mind is without color or shape, is "mere illumination," and its essence is "the same as space," making it difficult to contact, "like ultimate truth". It is characterized as "without root, without abode, without foundation, without characteristics" and is "beyond the sense faculties" and "not an object for logicians". Nāgārjuna is understood to present a "right view" by refuting inappropriate metaphysical views, rather than positing an "absolute emptiness" inexpressible through language. - **Vipaśyanā**: The text teaches ways to meditate on vipaśyanā, which "cuts through misinterpretations by discerning that phenomena are mind and that mind lacks any essence". Vipaśyanā arises from characteristics (conceptual representation), thorough investigation (understanding not well-understood topics), and discernment (bliss through liberation from well-understood topics). - **Key Instruction (_man ngag_)**: This refers to a specific, valued type of teaching, often oral and intimately delivered from teacher to student, designed to convey what to do in a clinical setting (in the medical context). Such instructions are characterized by simplicity and profundity, but are not primarily found in books; they originate from teachers with deep understanding. - **Mahāmudrā**: This term refers to both the nature of mind (empty yet vivid presence) and the meditation techniques for its realization. It is considered the culmination of the Vajrayāna path. Mabja's work is a compendium on realizing mahāmudrā. It can be approached as a "short path" not incorporating Secret Mantra practice, focusing on investigating the view and then receiving esoteric instructions. Its aim is to "point out mahāmudrā and show us how to see through the clouds of unknowing". Realizing "luminosity-mahāmudrā" is the ultimate abiding state, difficult to achieve without mahāmudrā instructions when relying only on Sūtra or Mantra main paths. - **Relationship between Sūtra and Secret Mantra**: While the _Commentary on the Enlightened Mind_ suggests that the Causal (Sūtra) and Resultant (Secret Mantra) Vehicles are identical in meaning, some sources note that texts like the _Four Treatises_ may covertly align with Secret Mantra systems (e.g., channel, wind, _tiklé_) without explicitly using its terminology to avoid confusion. The essence of the mahāmudrā path, according to Saraha, does not rely on Secret Mantra, being "without the three conditions, beyond the four joys, and superior to luminosity". However, combining mahāmudrā practice with Secret Mantra elements (like _karmamudrās_ and _abhiṣekas_) is considered acceptable. Mantras and deities are seen as present within the "nature of non-elaboration". - **Collection of Reasoning**: The _Ornament of Reason_ aims to demonstrate the absence of nature through reasoning, contributing to a "collection" or "compilation of reasoning" that some scholars define as five or six treatises. **V. Broader Philosophical Context and Distinctions** Mabja's work, and the philosophical tradition it represents, engages with and distinguishes itself from various other philosophical approaches: - **Critique of Substantialism**: Nagarjuna's critique of "substance" (_svabhava_), defined as "having its own existence," is central. He argues that a "dependent substance" is a contradiction, and that in the absence of an "effect" (_artha_), one cannot speak of a condition. - **Empiricism vs. Metaphysics**: Mabja's approach, consistent with Nāgārjuna's, critiques metaphysical conceptualizations of objects, similar to George Berkeley's refutation of a "material object." It argues that if an object appears to the perceiving mind in its own form, no external objective support is needed, as the perceiving mind and a material substance are of completely different natures. This contrasts with philosophers who emphasize the need for "pure reason" to grasp noumenal reality or extend cognition beyond experience. - **Rationality and Knowledge**: For Mabja, the "categories of convention are indeed totally reasonable" when fabrications arise interdependently, despite lacking inherent nature. This aligns with a view that human understanding cannot directly grasp "absolute possibility" which belongs solely to reason beyond empirical use. The structure of valid inference in Tibetan debate, based on Dharmakīrti, involves a subject, evidence, and probandum, with forward and reverse entailment. - **Language and Meaning**: The Nyāya school's definition of _śabda_ (valid verbal testimony) emphasizes understanding the intended meaning (_tātparya_) from a trustworthy person, requiring words to conform to conditions like expectancy (_ākāṅkṣā_), fitness (_yogyatā_), and proximity (_sannidhi_). This contrasts with the idea that language primarily deals with "frame-terms" and struggles to express what is not a frame. - **Critique of Enlightenment Rationalism**: The tradition represented by Mabja stands in contrast to the Enlightenment's tendency towards "abstract rationalism" and "anti-historicism," which formalized reason and impoverished the world by adhering to abstract criteria, preventing an appreciation of "ambivalent festive laughter". - **Purpose of Reason**: Similar to Kant, the work touches on the idea that reason, as a "faculty of principles," seeks systematic unity in cognition. However, this systematic unity is presented as a "logical principle" or "maxim" for organizing understanding's cognitions, rather than an objective law for things themselves. - **Role of Intuition and Schematism**: In line with Kant, the understanding relies on intuition for content, and "pure concepts of the understanding" require a relation to intuition to gain content. Kant's concept of "schematism" mediates between categories (universal concepts) and intuitions (temporal data), enabling the categories to apply to objects of sense. Without schemata, categories are empty functions. - **Moral Philosophy**: The text's emphasis on freedom from metaphysical extremes and liberation from suffering aligns with ethical goals. This resonates with Kant's move from merely formal principles of reason to "materialized" versions of the Categorical Imperative to determine obligatory ends, demonstrating that pure reason is both deontological and teleological. The purpose of reason, in Kant's view, includes guiding individuals towards a good will and establishing a "kingdom of ends" characterized by mutual respect. - **Contrast with Modernism**: Mabja's consistent approach contrasts with some postmodernist thinkers, such as Barthes, who might present theoretical oppositions as merely "figures of production" rather than arguments. It also differs from the idea that reality is unfinished and chaotic, requiring the human mind to actively create order, as found in Bergson's interpretation of pragmatism. The _Ornament of Reason_, therefore, serves not only as a comprehensive guide to Nāgārjuna's central philosophy but also implicitly positions itself within a broader landscape of philosophical inquiry, advocating for a reasoned, non-extreme, and pragmatically oriented understanding of reality and liberation.
