Jain Cosmology

Jain cosmology offers a unique and ancient picture of the universe, laid out in detail in the Tattvartha Sutra, chapter 3, and expanded in later Digambara (one of the two major Jain monastic traditions) works such as the Tiloyapannatti. Unlike traditions that describe the cosmos as a collection of planets or stars, Jain teaching describes it as a vast, living shape, a cosmic being known as Lok Purush. The word Lok means world or realm, and Purush means person or being. This being is not a god who created the universe; rather, the universe itself is imagined as the body of Lok Purush, whose form is divided into three tiers: the upper world, Urdhva Loka, the middle world, Madhya Loka, and the lower world, Adho Loka. Together these three tiers make up the entire realm where souls are born, live, die, and are reborn without end.

Madhya Loka is the part of Lok Purush corresponding to his waist and hips, and it is the world where humans, animals, plants, and countless other living beings dwell. It is described as a flat, disc-shaped land of continents and oceans, with Mount Meru, the axis of the world, rising at its exact center. In Jain teaching, Madhya Loka is the only one of the three worlds where a soul can achieve liberation. Liberation, Moksha, means freeing the soul from the endless cycle of birth and death, and only here do beings have the capacity to choose right action and practice non-violence in a way that sheds the karma binding them to that cycle. Madhya Loka is therefore considered a place of rare and precious opportunity, since neither the heavens above nor the hells below offer a soul any chance to escape the cycle it is already caught in. A human birth, brief and fragile as it is, is therefore treated in Jain teaching as the single rarest and most valuable opportunity any soul will ever encounter across its entire journey through the three worlds.

Above the middle world lies Urdhva Loka, corresponding to the chest, arms, and head of Lok Purush, described in the Tattvartha Sutra's fourth chapter as a series of heavenly realms, each more beautiful and blissful than the one beneath it. Souls that have accumulated good karma through kind thoughts, words, and actions are reborn here as gods or celestial beings, experiencing great pleasure, long life, and happiness. Their stay, however, is never permanent: once the good karma that placed them there is exhausted, they fall back into a lower realm to continue the cycle. No matter how high a soul rises within Urdhva Loka, Jain teaching insists it has not yet achieved liberation, since it remains bound by karma even at the summit of celestial pleasure. A god enjoying the highest heaven and an insect crawling through Madhya Loka are, in this sense, closer to one another than either is to a liberated soul, since both remain equally trapped within Samsara.

Below the middle world lies Adho Loka, matching the legs and feet of Lok Purush, the realm of hells where souls that have accumulated bad karma through violence, lying, stealing, or greed are reborn. The Tattvartha Sutra describes these hells across multiple descending levels of increasing suffering. As with the heavens, this punishment is never eternal: once the bad karma that led a soul there is exhausted, it is reborn elsewhere to continue its journey. Adho Loka also includes the realms of certain other beings associated with darkness and suffering, but like the heavens above, every one of these places is a temporary stop rather than a final destination, since Jain teaching holds that no soul, however deep its suffering, is ever condemned to any single realm without end.

Altogether, the three worlds of Lok Purush make up what Jain teaching calls Samsara, the cycle of birth, death, and rebirth. Every soul, whether a tiny insect, a powerful god, or a suffering hell-being, travels endlessly within these three tiers, driven by the karma it has accumulated. The body of Lok Purush is described as vast beyond measure, with no beginning or end in time: in Jain thought the universe was never created and will never be destroyed, only endlessly reshaped through these recurring cycles of expansion and contraction. The human form given to this cosmic map is meant to help the mind grasp the universe as one connected, organic whole rather than a scattered collection of unrelated realms.

The ultimate goal of Jain practice is to leave the three worlds entirely. When a soul purifies itself completely, through non-violence, truthfulness, fasting, meditation, and the other disciplines Jain teaching prescribes, it sheds all karma and rises to the very top of the universe, beyond Lok Purush's own head. This place is called Siddhashila, the realm of liberated souls, where the soul exists forever in pure, eternal consciousness, wholly free from birth, death, and suffering of any kind. The image of Lok Purush is therefore not only a map of where souls presently live; it stands as a constant reminder that every soul, in principle, can rise above the body of the cosmos itself and attain perfect and permanent freedom, no matter how deep within Adho Loka or how high within Urdhva Loka that soul's present journey happens to have carried it.
