Snigdha and Rūkṣa in Jain Pudgala Ontology: Bandha, Vidyut, and a Critical Comparison with Electric Charge

Abstract

Jain philosophy presents pudgala—material substance—as possessing distinctive attributes, including the tactile qualities snigdha and rūkṣa. In discussions of material combination, these qualities are associated with bandha, or binding. The Ṣaṭkhaṇḍāgama, particularly its Vargaṇā-khaṇḍa and the accompanying Dhavalā commentary, develops a systematic account of material aggregates and their transformations. Within this textual setting, vidyut appears among a group of material phenomena associated with sādi-vaisrasika-bandha. The text also describes vidyut as a luminous, highly intense phenomenon found in clouds. Pūjyapāda Devanandin’s Sarvārthasiddhi, in its exposition of bandha, provides a further account linking snigdha–rūkṣa qualities with natural material binding and names phenomena that include vidyut.

This article examines these passages as textual and philosophical evidence before comparing them with the modern concept of electric charge and the physics of atmospheric electricity. It argues that the Jain account merits close study as a distinctive ontology of material qualities, combination, and transformation. At the same time, it cautions against treating snigdha and rūkṣa as exact equivalents of positive and negative electric charge, or bandha as identical to electromagnetic interaction. Such correspondences may be explored as modern interpretations, but they must not be attributed to the ancient texts unless the texts themselves warrant them. The article therefore distinguishes primary textual statements, commentary, interpretive analogy, and modern physical explanation. This source-critical approach makes it possible to appreciate the conceptual significance of the Jain account without either diminishing its philosophical value or overstating its equivalence to contemporary physics.

1. Introduction

The Jain understanding of matter is embedded in a broader account of reality in which substances possess enduring identity while undergoing changing modes. Among the six substances recognized in the classical Jain framework, pudgala is material substance. It is characterized by attributes that include colour, taste, smell, and touch. Jain texts further discuss the ways in which material units and aggregates combine, separate, and transform.

Within this account, snigdha and rūkṣa occupy a significant place. The terms are commonly rendered as “smooth” or “unctuous” and “rough” or “dry,” respectively, although no single English equivalent fully captures their technical use in Jain ontology. They are not merely descriptions of how an object feels to the hand. In discussions of material combination, they are treated as qualities relevant to whether and how material units bind.

The subject becomes especially interesting where the textual discussion of bandha is connected with natural material phenomena, including clouds and vidyut. The latter term is often translated as “lightning” or “electricity,” depending on textual context and the interpretive choices of a translator. The presence of vidyut in a discussion of material transformation invites comparison with modern knowledge of atmospheric electricity. Such comparison, however, requires care: a shared term or a broad resemblance between explanations does not by itself establish that two accounts describe the same physical mechanism.

The purpose of this article is threefold:

1. To examine the relevant Jain textual statements concerning snigdha, rūkṣa, bandha, and vidyut.
2. To distinguish what is stated in the texts from what is supplied by commentarial explanation or modern interpretation.
3. To compare the Jain account with electric charge and atmospheric electricity while identifying both meaningful points of contact and important differences.

The central claim is deliberately limited. The Jain sources offer a systematic account in which material qualities are associated with binding and material transformations, and in which vidyut is included among phenomena discussed in this framework. This provides a legitimate basis for philosophical and historical comparison. It does not, without further evidence, establish that the sources formulated the modern theory of electric charge or the contemporary physical explanation of lightning.

2. Textual and methodological approach

This study follows a source-critical method. It treats the relevant textual layers separately rather than combining statements from different works into a single reconstructed doctrine.

Four levels of evidence are distinguished:

• Early doctrinal text: the Ṣaṭkhaṇḍāgama, attributed in the Digambara tradition to Ācāryas Puṣpadanta and Bhūtabali.
• Commentarial exposition: the Dhavalā, associated with Ācārya Vīrasena, which explains and elaborates the Ṣaṭkhaṇḍāgama.
• A related philosophical exposition: Pūjyapāda Devanandin’s Sarvārthasiddhi, a commentary on the Tattvārtha Sūtra.
• Modern comparative interpretation: explanations that relate snigdha and rūkṣa to positive and negative electric charge, or compare bandha with physical attraction.

These levels are related, but they are not interchangeable. A statement in a commentary may clarify how a commentator understood a doctrine; it should not automatically be represented as the exact wording of the root text. Similarly, a modern comparison may be intellectually productive without being a literal translation of the classical terminology.

The textual quotations below follow the editions and digitized materials identified in the references. Since editions of Jain works may differ in numbering, spelling, segmentation, and presentation of the root text and commentary, references to a passage should be checked against the specific edition used for formal publication. Where the precise wording of a Prakrit passage is uncertain in a digitized transcription, the article avoids presenting a reconstructed reading as though it were a verified critical text.

3. The Ṣaṭkhaṇḍāgama and its place in the Jain textual tradition

The Ṣaṭkhaṇḍāgama holds a central position in the Digambara scriptural tradition. Traditional accounts describe a transmission of doctrinal knowledge through teachers and disciples, with Ācārya Dharasena transmitting surviving teachings to Puṣpadanta and Bhūtabali, who are associated with the work’s composition and preservation. The Dhavalā commentary, traditionally attributed to Vīrasena, later provides extensive explanation of the text.

The precise historical dating of the Ṣaṭkhaṇḍāgama’s composition and written redaction is not uniformly established. Proposed chronologies differ, and traditional accounts should be identified as such rather than treated as uncontested historical dates. It is therefore safer to describe the work as an early and foundational Digambara text whose surviving form reflects an important process of textual preservation, rather than assigning it an exact date without qualification.

The present inquiry focuses on the Vargaṇā-khaṇḍa, especially the material dealing with bandha and bandhanīya. The section examines material aggregates, their qualities, and the conditions under which they undergo binding. The Dhavalā is essential to understanding this material because it supplies detailed explanations and classifications that are not always explicit in the brief root statements.

The historical significance of the work for this article lies not in an assumed priority over all other knowledge systems, but in the fact that it preserves a systematic Jain discussion of material qualities and transformations. Establishing the exact relationship between this account and modern physics requires textual and conceptual comparison, not a claim of direct equivalence.

4. Pudgala and its material attributes

In Jain ontology, pudgala is material substance. It is associated with the characteristics of colour (varṇa), taste (rasa), smell (gandha), and touch (sparśa). These are not accidental descriptions added by an observer; they belong to the account of material reality.

The Tattvārtha Sūtra identifies material substance through these attributes. In commonly used editions, the relevant sūtra is numbered 5.23, although numbering and editorial presentation should always be checked against the edition cited. The subsequent discussion includes additional properties and distinctions of material substance.

Within the category of touch, Jain texts discuss qualities that include snigdha and rūkṣa. In ordinary language, these may suggest smoothness, unctuousness, roughness, or dryness. Their philosophical function, however, extends beyond a simple sensory classification. They are also invoked in explanations of material combination.

A central interpretive question is whether these qualities should be understood exclusively as tactile sensations or also as technical material dispositions. The texts’ use of them in the theory of bandha supports the latter role: they participate in an explanation of the conditions under which material units or aggregates bind. This does not mean that their technical meaning can be reduced to any single modern physical quantity.

5. Bandha: material binding and its conditions

The Tattvārtha Sūtra states the relationship between snigdha–rūkṣa and bandha in the sūtra commonly presented as:

स्निग्धरूक्षत्वाद् बन्धः।

Snigdha-rūkṣatvād bandhaḥ.

A concise translation is: “Binding occurs because of the qualities of snigdha and rūkṣa.”

The statement is significant because it identifies material qualities as relevant conditions of binding. It should not, however, be isolated from the sūtras that follow. The adjoining discussion qualifies the account by referring to degrees of quality and to relations among material units. The resulting doctrine is therefore more nuanced than a simple rule that all unlike qualities attract and all like qualities repel.

The sequence commonly cited in editions of the Tattvārtha Sūtra includes the following:

• स्निग्धरूक्षत्वाद् बन्धः — binding is associated with snigdha and rūkṣa.
• न जघन्यगुणानाम् — the lowest degree of quality is not sufficient under the stated condition.
• गुणसाम्ये सदृशानाम् — similarity in degree is relevant to the binding rule.
• द्वयधिकादिगुणानां तु — a further qualification concerns differences in degree.

Sūtra numbering varies between editions and commentarial traditions. The Sanskrit wording, rather than a number alone, should therefore be used to identify the passage in comparative work.

The important point is that bandha is not described by a single undifferentiated attraction principle. The textual discussion considers qualities and their degrees. It concerns the combination or binding of material units within Jain ontology. Translating bandha simply as “electrostatic attraction” would impose a modern physical category that the text itself does not name.

This distinction is central to the present study. Bandha and physical attraction may be compared at the level of a broad explanatory function—both concern relations between material entities—but the mechanisms and theoretical contexts should not be assumed to be identical.

6. Sādi-vaisrasika-bandha in the Ṣaṭkhaṇḍāgama

The Ṣaṭkhaṇḍāgama’s discussion of bandha includes the category sādi-vaisrasika-bandha. The term vaisrasika is associated with natural or spontaneous processes, while sādi indicates a beginning or a bounded sequence in the relevant classification. The precise technical force of the compound should be interpreted within the text and its commentary rather than by relying on a loose modern equivalent.

In the relevant discussion, the Dhavalā explains binding in relation to differences in snigdha and rūkṣa. The Hindi exposition of the passage summarizes the doctrine by stating that dissimilar snigdhatā and dissimilar rūkṣatā are associated with binding. Another passage explains that material units of the same kind do not necessarily bind merely because they share the same quality; the degrees and relations of qualities matter.

The root text and commentary should be read together but not collapsed into one statement. The root text supplies the doctrinal classification; the commentary clarifies how the relevant distinctions are to be understood. In particular, the discussion of degrees prevents the doctrine from being simplified into the formula “opposites attract.”

The Dhavalā further relates the binding-result of material aggregates to a series of material forms and phenomena. The list includes abhrā, megha, sandhyā, vidyut, ulkā, and other named forms. In the accompanying explanation, these are treated as transformations or manifestations of material aggregates within the classification of sādi-vaisrasika-bandha.

This passage is important for the article’s central question. It places vidyut within a textual account of material transformation associated with bandha. It does not, by that fact alone, provide a complete causal theory of lightning in the sense used by contemporary atmospheric physics. The distinction between a classification of phenomena and a detailed physical mechanism must be maintained.

7. Megha and vidyut: clouds and lightning in the textual account

The relevant Vargaṇā-khaṇḍa discussion includes megha—clouds—and vidyut. The commentary distinguishes cloud-related forms and describes vidyut as a luminous phenomenon associated with clouds. The Hindi exposition characterizes it as having intense brilliance and a changing or restless appearance, and identifies it as occurring in clouds.

The textual significance is twofold.

First, megha and vidyut are not introduced merely as metaphors. They occur in a discussion of material aggregates and their transformations. Their inclusion supports the view that the text is addressing phenomena understood within its material ontology.

Second, the description connects vidyut with clouds in an observable natural setting. This is a meaningful point of comparison with modern atmospheric electricity, where lightning is a visible electrical discharge occurring in the atmosphere and commonly associated with thunderstorms.

Nevertheless, the article must not add a causal sequence that the cited passage does not explicitly state. In particular, the claim that “snigdha clouds and rūkṣa clouds meet, combine, and generate energy” should not be presented as a direct quotation or as the unambiguous wording of the scripture unless a specific passage in the chosen edition establishes each part of that statement. The source-grounded formulation is more restrained: the text relates snigdha–rūkṣa to bandha, classifies certain natural material transformations under sādi-vaisrasika-bandha, and includes megha and vidyut among the phenomena discussed.

This formulation preserves the textual connection without extending it beyond the evidence.

8. Pūjyapāda Devanandin and the Sarvārthasiddhi

Pūjyapāda Devanandin is generally placed in the fifth or sixth century CE, although exact dates remain a matter of scholarly and traditional chronology. Some accounts assign him a more specific date range, but such dates should be identified as proposed rather than treated as certain.

His Sarvārthasiddhi, a Sanskrit commentary on the Tattvārtha Sūtra, is a significant source for understanding the interpretation of Jain doctrines of matter and binding. In explaining bandha, the work discusses snigdha and rūkṣa as qualities relevant to natural binding and refers to phenomena that include vidyut, ulkā, water streams, fire, and the rainbow.

A key phrase in the Sarvārthasiddhi is:

स्निग्धरूक्षत्वगुणनिमित्तो विद्युदुल्काजलधाराग्नीन्द्रधनुरादिविषयः।

The wording associates the subject of natural binding with the qualities of snigdha and rūkṣa and names phenomena including vidyut, ulkā, jaladhārā, agni, and indradhanus. Its context is the explanation of vaisrasika-bandha—natural binding, not binding brought about by deliberate human action.

The passage is important evidence for the way Pūjyapāda’s commentary connects the doctrine of snigdha–rūkṣa with natural material phenomena. It should be quoted in its actual commentarial context. It does not warrant translating the phrase as “snigdha and rūkṣa generate electrical energy,” nor does it explicitly identify the two qualities with the modern signs of positive and negative charge.

Pūjyapāda’s account and the Ṣaṭkhaṇḍāgama passage are mutually relevant, but they are separate textual witnesses. A publication-quality argument should identify the work, section, edition, and page for each quotation, and should not present the later commentary as though it were part of the earlier root text.

9. From vidyut to electric charge: a necessary distinction

The word vidyut has a semantic range that includes lightning and electrical phenomena. In a passage describing a luminous phenomenon occurring in clouds, “lightning” is often the most contextually appropriate English translation. In other contexts, “electricity” may be a reasonable rendering. The translation must be guided by the passage rather than by the modern scientific meaning alone.

Electric charge, by contrast, is a specific physical property. In modern physics, charge is a measurable property of matter that determines how particles and bodies interact electromagnetically. Electric charge is conventionally described as positive or negative, and its interactions are represented quantitatively through physical laws.

Accordingly, three terms should be kept distinct:

Jain term	Textual or doctrinal role	Modern comparison	Caution
Snigdha	A material/tactile quality involved in the account of bandha	Sometimes interpreted as corresponding to positive charge	The equivalence is interpretive, not a literal translation established by the term alone
Rūkṣa	A material/tactile quality involved in the account of bandha	Sometimes interpreted as corresponding to negative charge	The equivalence is interpretive, not a literal translation established by the term alone
Bandha	Binding or combination of material units/aggregates	Material attraction or combination	Not automatically identical to electromagnetic force
Vidyut	A named natural phenomenon, especially lightning in cloud-related context	Lightning or an atmospheric electrical phenomenon	Not synonymous in every context with electric charge or energy
Urjā / energy	Not to be inferred solely from the occurrence of vidyut	Energy in modern physical theory	A claim about energy generation requires explicit textual or scientific support
Guṇa	Quality or attribute within Jain ontology	A property or parameter, in a broad comparative sense	Not equivalent to a specific measurable physical quantity without further argument

Modern Jain writers and interpreters have proposed that snigdha and rūkṣa can be understood through the analogy of positive and negative electric charge. This may provide a useful interpretive model, particularly when discussing attraction, repulsion, and material combination. Yet a proposed correspondence should remain explicitly identified as a modern interpretation unless supported by a direct statement in the primary source.

The distinction is not merely terminological. A tactile or ontological quality in a classical system and a quantified physical property in modern physics belong to different explanatory frameworks. A comparison can illuminate each framework, but it cannot erase their conceptual differences.

10. Modern physics: electric charge and atmospheric electricity

In modern physics, electric charge is a fundamental property associated with electromagnetic interaction. The interaction between charged bodies depends on the magnitude and sign of their charges, their separation, and the physical conditions of the system. Like charges repel and unlike charges attract in the familiar electrostatic description, but this rule is part of a quantitatively defined theory.

Lightning is not explained solely by the statement that opposite charges attract. In thunderstorms, complex processes produce and separate electrical charges within the cloud system. This charge separation establishes electric fields. When the field becomes sufficiently intense to overcome the insulating properties of the surrounding air along a path, electrical breakdown and discharge can occur. The visible lightning flash is part of this discharge process.

The modern explanation therefore includes processes and measurable quantities not present in the cited Jain passages in the same form: charge magnitude, electric field, potential difference, conductivity, breakdown strength, and the dynamics of atmospheric charge separation. The comparison should not imply that the ancient account contains these modern formulations in an unexpressed or hidden form.

There is, nevertheless, a legitimate comparative question: how do different knowledge systems account for material combination and visible natural phenomena? Jain ontology approaches the question through material qualities, binding, and transformation. Modern physics approaches it through measurable electrical properties, fields, and discharge processes. The two can be compared in terms of their explanatory aims and conceptual structures, while preserving the differences in their terminology, methods, and evidentiary standards.

11. Points of comparison and limits of equivalence

The comparison between Jain snigdha–rūkṣa doctrine and modern electric charge is most productive when organized around specific questions rather than a broad assertion of identity.

11.1 Material qualities and physical properties

Both frameworks treat material reality as possessing properties relevant to interactions. Jain texts use snigdha and rūkṣa as qualities in an account of binding. Modern physics uses electric charge as a measurable property relevant to electromagnetic interaction.

This is a structural resemblance at a broad level: properties of material entities are used to explain relations among them. It does not establish that the properties are identical.

11.2 Binding and attraction

The Jain concept of bandha concerns material binding or combination. Electrostatic attraction is one physical interaction that can contribute to the behavior of charged matter. The concepts may therefore be compared in the general domain of material interaction.

However, bandha in Jain ontology is embedded in a broader metaphysical and doctrinal system. Electrostatic attraction is a specific interaction described by physical theory. Treating one as a direct synonym for the other would obscure the scope and function of both concepts.

11.3 Similarity, difference, and degree

The Jain discussion of bandha includes qualifications involving degrees of snigdha and rūkṣa. This is a significant feature of the doctrine and should be retained in any comparative account.

Modern electrostatics also considers quantitative values, but the Jain classification of guṇa should not be assumed to map directly onto charge magnitude. A valid equivalence would require a demonstrable correspondence between the relevant categories and measurable quantities. The cited passages do not by themselves establish such a mapping.

11.4 Natural phenomena and vidyut

The inclusion of vidyut among material phenomena associated with natural binding is a particularly valuable subject for further research. It demonstrates that the texts place lightning or an electrical phenomenon within a systematic discussion of material forms and transformations.

It does not, without additional textual evidence, establish a complete theory of atmospheric charge separation or electrical discharge. The distinction between naming or classifying a phenomenon and explaining its mechanism is essential to a fair comparison.

11.5 Historical significance

The Jain sources deserve examination in their own intellectual and historical setting. Their treatment of material qualities, binding, and transformation can contribute to the history of philosophical reflection on matter. The historical significance of the doctrine does not depend on proving that it anticipated every element of modern physics.

A careful history of ideas can recognize conceptual sophistication without imposing a retrospective identity between distinct systems of thought.

12. Source layers and interpretive responsibility

For clarity, the article’s principal claims can be assigned to their respective evidentiary layers:

Source layer	What it supports	What should not be attributed to it without further evidence
Ṣaṭkhaṇḍāgama	A systematic discussion of material aggregates, bandha, and related classifications	A modern mathematical theory of electric charge
Dhavalā commentary	Explanatory detail concerning the relevant qualities, degrees, binding, and material phenomena including megha and vidyut	A literal identity between snigdha–rūkṣa and positive/negative charge unless explicitly stated in the cited passage
Tattvārtha Sūtra	The concise doctrinal relationship between snigdha–rūkṣa and bandha, with qualifications in adjoining sūtras	A complete physical mechanism for lightning
Pūjyapāda’s Sarvārthasiddhi	A commentarial exposition linking snigdha–rūkṣa with natural binding and naming phenomena including vidyut	The claim that the passage defines charge or energy in the modern sense
Modern Jain interpretation	A proposed correspondence between classical qualities and electrical polarity	Proof that the proposed mapping is the only possible or original meaning
Modern physics	Quantitative accounts of electric charge, fields, and atmospheric discharge	Validation or invalidation of a classical metaphysical system as a whole

This distinction is not intended to diminish the authority of the Jain sources within their own tradition. It is a methodological requirement for scholarly publication, particularly in an interdisciplinary journal where readers may approach the texts from philosophy, religious studies, history, or physical science.

13. Discussion

The passages considered here present a coherent set of questions about matter: What qualities characterize material entities? Under what conditions do material units bind? How do aggregates undergo transformation? How should natural phenomena such as clouds and lightning be situated within a general account of material reality?

The Jain answer is articulated through its own conceptual vocabulary. Pudgala is the material substance; snigdha and rūkṣa are relevant qualities; bandha describes binding; and vidyut is included among natural phenomena discussed in connection with material transformation. The Tattvārtha Sūtra, the Ṣaṭkhaṇḍāgama, the Dhavalā, and the Sarvārthasiddhi each contribute to this account at different textual levels.

The modern scientific comparison begins with a different question: what measurable properties and physical processes account for electrical interactions and lightning? Modern physics answers through charge, fields, charge separation, electrical breakdown, and discharge. Its explanations are mathematical and experimentally testable in ways that should not be retroactively attributed to the Jain texts.

The two approaches can still be placed in dialogue. Both are concerned with the behavior of material reality and the conditions under which observable changes occur. Both employ concepts that connect properties of material entities with interactions and outcomes. These similarities justify comparative study, but the differences in explanatory scope and method remain substantial.

The most defensible conclusion is therefore neither that the Jain doctrine is identical to modern electrostatics nor that the comparison is meaningless. Rather, the Jain account offers a distinct philosophical model of material qualities and binding that can be examined alongside modern concepts of charge and atmospheric electricity. The comparison is strongest when it is specific, textually grounded, and explicit about its limits.

14. Conclusion

Jain discussions of snigdha and rūkṣa form part of a broader ontology of pudgala and its transformations. The Tattvārtha Sūtra connects these qualities with bandha and qualifies the account through considerations of degree. The Ṣaṭkhaṇḍāgama and its Dhavalā commentary develop the treatment of material aggregates and natural binding, including references to megha and vidyut. Pūjyapāda’s Sarvārthasiddhi provides a further exposition in which snigdha–rūkṣa qualities are associated with natural binding and phenomena such as lightning.

These sources establish a meaningful textual basis for examining Jain thought on matter, binding, and natural phenomena. They also justify a careful comparison with modern electric charge and atmospheric electricity. They do not, on the evidence discussed here, establish that snigdha and rūkṣa are exact equivalents of positive and negative electric charge, that bandha is identical to electromagnetic force, or that the texts provide the modern physical mechanism of lightning.

The scholarly value of the comparison lies in respecting both systems as they are: the Jain account as a historically situated philosophical ontology, and modern physics as a quantitative, experimentally developed science. By preserving the textual wording, separating commentary from root text, and distinguishing interpretation from direct evidence, the study can make a substantive contribution to interdisciplinary discussion without manufacturing claims or overstating historical equivalence.
