What is the central idea in Jainism regarding the world?

The entire world is animated, including non-living things

Before the birth of Vardhamana, later known as Mahavira, in the sixth century BCE, the foundational philosophy of the Jains was already in existence within northern India. In accordance with Jaina tradition, Mahavira was preceded by 23 esteemed teachers, or tirthankaras, who are figuratively regarded as guides helping individuals navigate the river of existence.

A fundamental tenet of Jainism centers around the belief that the entirety of the world possesses a form of life, extending even to seemingly lifeless entities such as stones, rocks, and water. The cornerstone of Jaina philosophy is the principle of non-injury towards all living beings, with special focus on humans, animals, plants, and insects. This principle of ahimsa, prominently featured within Jainism, has left a lasting imprint on the broader landscape of Indian thought.
