In Jain philosophy, indriya (Skt./Prakrit: indriya, often translated as “sense-faculty” or “sense-organ”) refers to the fundamental capacities through which living beings perceive and interact with the world. The doctrine of indriyas is central to Jain ontology, cosmology, ethics, and the classification of living beings (jīva-samās). Jainism identifies five indriyas—touch, taste, smell, sight, and hearing—but also distinguishes between the physical sense-organs (dravyendriya) and the psychic or functional sense-capacities (bhāvendriya). This dual structure allows Jain thinkers to explain perception not merely as a bodily process but as a karmically conditioned activity of the soul.
Indriyas are used to classify beings into one-sensed through five-sensed categories, forming the basis of Jain environmental ethics and nonviolence. A one-sensed being (e.g., plants) possesses only touch, while a five-sensed being (e.g., humans) possesses all five. The number of indriyas possessed by a jīva determines its vulnerability, karmic potential, and the severity of harm caused to it. Thus, the doctrine of indriyas is not only descriptive but also normative, shaping the Jain ethic of ahiṃsā.

Across Digambara and Śvetāmbara traditions, the classification of indriyas is consistent, though commentarial nuances differ. Digambara texts often emphasize the karmic mechanisms that obstruct or enable sensory functioning, while Śvetāmbara commentariesDraft overviewCommentariesIn Jainism, “commentaries” (often termed **ṭīkā**, **vṛtti**, **bhāṣya**, **vārttika**, or **niryukti**) are systematic explanations of earlier authoritative texts, especially sūtras and āgamas.

Thus, indriya doctrine is a foundational component of Jain metaphysics, ethics, and soteriology, linking the structure of living beings, the mechanics of perception, and the path to liberation.
