Explanation:

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.
