In Jain philosophical literature, “energy” is not treated as a single unified category in the modern scientific sense. Instead, Jain thinkers describe multiple modes of potency, activity, and causal efficacy across living beings (jīva), karmic matterDraft overviewKarmic matterIn Jain philosophy, **karmic matter (karma pudgala)** refers to a subtle form of material particles that bind to the soul (jīva) due to its activities, passions, and vibrations.

Energy is understood through the broader ontology of six dravyasDraft overviewSix dravyasIn Jain philosophy, "dravyas" are the fundamental substances that constitute reality. The doctrine of six dravyas is central to Jain metaphysics and appears across both Digambara and Śvetāmbara traditions, with minor dif… (substances), each possessing its own inherent guṇa (quality) and śakti (capacity). Pudgala, the material substance, is the closest analogue to physical energy because it includes both matter and what classical texts call tejas (heat, fire) and vāyu (air), which function as forms of energetic activity. Jīva possesses its own intrinsic vitality (upayoga), expressed as consciousness and activity. Karmic particles carry a subtle form of causal potency that influences the soul’s capacities.
Across traditions, Jain authors emphasize that energy is neither created nor destroyed; substances are eternal, and their modes (paryāya) continuously transform. This aligns conceptually with conservationDraft overviewConservationIn Jain thought, “conservation” is not a modern environmental policy term but a principle emerging from the core doctrines of **ahiṃsā (non‑violence)**, **aparigraha (non‑possessiveness)**, and the recognition that **all… principles, though Jainism frames it metaphysically rather than mathematically.

Thus, “energy” in Jain thought is best understood as the dynamic interplay of eternal substances undergoing constant modification.
Modern Jain scholarship often correlates tejas with thermodynamic heat, vāyu with kinetic motion, and pudgalaDraft overviewPudgalaIn Jain philosophy, **pudgala** (often called *pudgalastikaya* when emphasizing its extension) is the fundamental category of matter and material energy. It is one of the six eternal substances (*ṣaḍ-dravya*) that consti…’s fine particles with forms of subtle materiality. However, these comparisons are interpretive and not explicit in primary texts. Jainism does not propose a unified physical theory of energy; instead, it offers a metaphysical framework in which all change—physical, mental, karmic—is an expression of the inherent capacities of substances interacting according to natural laws.
