Dravya

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. The Vaisheshika school of Indian philosophy also deals with a concept of dravya.

Dravya in Jainism are fundamental entities, called astikaya (literally, 'collection that exists'). They are believed to be eternal, and the ontological building blocks that constitute and explain all existence, whether perceived or not.

Both Śvētāmbara and Digambara traditions hold that there are six dravyas which can be categorized into sentient and non-sentient:

In both traditions, the substance of space is conceptualized as "world space" (lokakasha) and "non-world space" (alokiakasha). Further, both soul and matter are considered active ontological substances, while the rest are inactive.

Out of the six dravyas, five except time have been described as astikayas, that is, extensions or conglomerates. Since like conglomerates, they have numerous space points, they are described as astikaya. There are innumerable space points in the sentient substance and in the media of motion and rest, and infinite ones in space; in matter they are threefold (i.e. numerable, innumerable and infinite). Time has only one; therefore it is not a conglomerate. Hence the corresponding conglomerates or extensions are called—jivastikaya (soul extension or conglomerate), pudgalastikaya (matter conglomerate), dharmastikaya (motion conglomerate), adharmastikaya (rest conglomerate) and akastikaya (space conglomerates). Together they are called pancastikaya or the five astikayas.

Jiva means "soul" in Jainism, and is also called jivatman. It is a core concept and the fundamental focus of the Jain theology. The soul is believed to be eternal, and a substance that undergoes constant modifications, in every life, after every rebirth of a living being. Jiva consists of pure consciousness in the Jain thought, has innate "free will" that causes it to act but is believed to be intangible and formless. It is the soul that experiences existence and gains knowledge, not mind nor body both believed to a heap of matter. Jain philosophy further believes that the soul is the mechanism of rebirth and karma accumulation. It is the same size in all living beings, such as a human being, a tiny insect and a large elephant. Jiva is everywhere, filling and infused in every minuscule part of the entire loka (realm of existence), according to Jainism. The soul has the potential to reach omniscience and eternal bliss, and end the cycles of rebirth and associated suffering, which is the goal of Jain spirituality.

According to Jain philosophy, this universe consists of infinite jivas or souls that are uncreated and always existing. There are two main categories of souls: un-liberated mundane embodied souls that are still subject to transmigration and rebirths in this samsara due to karmic bondage and the liberated souls that are free from birth and death. All souls are intrinsically pure but are found in bondage with karma since beginning-less time. A soul has to make efforts to eradicate the karmas attain its true and pure form.
