Dravya (Sanskrit: द्रव्य) means substance or entity

According to the Jain philosophy, the universe is made up of six eternal substances: sentient beings or souls (jīva), non-sentient substance or matter (pudgala), principle of motion (dharma), the principle of rest (adharma), space (ākāśa) and time (kāla)

The latter five are united as the ajiva (the non-living)

As per the Sanskrit etymology, dravya means substances or entity, but it may also mean real or fundamental categories

Jain philosophers distinguish a substance from a body, or thing, by declaring the former as a simple element or reality while the latter as a compound of one or more substances or atoms

They claim that there can be a partial or total destruction of a body or thing, but no dravya can ever be destroyed
