Dravya

Dravya (द्रव्य) means “substance” or “entity.” It is the first and most fundamental category (padartha) of the Vaisheshika system, denoting the substratum that underlies qualities and actions.

Overview

In Vaisheshika ontology, dravya is the entity that possesses qualities (guna) and actions (karma). There are nine dravyas: prithvi (earth), apas (water), tejas (fire), vayu (air), akasha (ether), kala (time), dik (space), atman (self), and manas (mind). Each dravya is a unique particular (svalakshana) that inheres in its own universal (samanya).

Philosophical Context

Dravya is the foundation of Vaisheshika realism. The school argues that substances are real, permanent entities that undergo change through the addition and subtraction of qualities and actions. The nine-fold classification provides a complete map of the physical and metaphysical world. Note that karma (action) is a separate padartha in the Vaisheshika scheme — the second category, not a substance — and some later Nyaya-Vaisheshika thinkers debated details of the enumeration (e.g., whether time and space are ultimately one substance or two).

Interpretations

The early Vaisheshika school (Kanada) recognized only six physical dravyas (excluding time, space, self, and mind), which were later expanded. The Buddhist Abhidharma tradition recognizes a different set of dharmas (phenomena) as the ultimate substances, rejecting the Vaisheshika categories. The Samkhya school uses a similar concept of dravya but limits it to 24 tattvas (principles) derived from prakriti.
