Jainism is one of the world's oldest living religions, with roots in the Shramana movement of ancient India that also gave rise to Buddhism. Its 24th and most recent Tirthankara (ford-maker, liberated teacher) was Vardhamana Mahavira, a contemporary of the Buddha in the 6th century BCE. Jains number around 4–5 million today, mostly in India, but their ethical influence — particularly the doctrine of ahimsa — has been disproportionate to their numbers. Mahatma Gandhi drew directly from Jain ethics in developing his philosophy of non-violent resistance.
Jain cosmology is atheistic — there is no creator god. The universe is eternal and self-sustaining, governed by natural laws. What exists are souls (jiva) and non-soul matter (ajiva). Every action — especially harmful action — generates karma, conceived in Jainism not metaphorically but literally: as subtle matter that clings to the soul and weighs it down, binding it to rebirth in various forms depending on its nature.
The path to liberation (moksha) is the progressive shedding of karma through right knowledge, right faith, and right conduct. The liberated soul rises naturally to the highest point of the universe — the Siddhashila — where it remains in eternal, blissful awareness, beyond rebirth, beyond suffering, beyond all limitation. The Tirthankaras are not gods to be petitioned but models to be emulated — beings who achieved liberation and whose example shows the path.
A man should wander about treating all creatures in the world as he himself would be treated. This is the quintessence of wisdom — not to kill, not to lie, not to steal, not to take what is not given.
— Sutrakritanga (Jain scripture)
