Jain cosmology


Jain cosmology is the description of the shape and functioning of the Universe (loka) and its constituents (such as living beings, matter, space, time etc.) according to Jainism. Jain cosmology considers the universe, as an uncreated entity, existing since infinity, having neither beginning nor end. Jain texts describe the shape of the universe as similar to a man standing with legs apart and arm resting on his waist. This Universe, according to Jainism, is broad at the top, narrow at the middle and once again becomes broad at the bottom.

According to Jains, the Universe is made up of six simple and eternal substances called dravya classified as follows:

Conventional time (vyavahāra kāla) is perceived by the senses through the transformations and modifications of substances. Real time (niścaya kāla), however, is the cause of imperceptible, minute changes (called vartanā) that go on incessantly in all substances.

The Jain doctrine postulates an eternal and ever-existing world which works on universal natural laws. The existence of a creator deity is overwhelmingly opposed in the Jain doctrine. Mahāpurāṇa, a Jain text authored by Ācārya Jinasena is famous for this quote:

According to Jains, the universe has a firm and an unalterable shape which is measured in the Jain texts by means of a unit called Rajju which is supposed to be very large. The Digambara sect of Jainism postulates that the universe is fourteen Rajju high and extends seven Rajjus from north to south. Its breadth is seven Rajjus at the bottom and decreases gradually till the middle where it is one Rajju. The width then increases gradually till it is five Rajju and again decreases till it is one Rajju. The apex of the universe is one Rajju long, one Rajju wide and eight Rajju high. The total space of the world is thus 343 cubic Rajju. The svetambara view differs slightly and postulates that there is constant increase and decrease in the breadth and the space is 239 cubic Rajju. Apart from the apex which is the abode of liberated beings, the universe is divided into three parts. The world is surrounded by three atmospheres: dense-water, dense-wind and thin-wind. It is then surrounded by infinitely large non-world which is absolutely empty.

The whole world is said to be filled with living beings. In all the three parts, there is the existence of very small living beings called nigoda. Nigoda are of two types: nitya-nigoda and Itara-nigoda. Nitya-nigoda are those which will reborn as nigoda throughout eternity where as Itara-nigoda will be reborn as other beings too. The mobile region of universe (Trasandi) is one Rajju wide, one Rajju broad and fourteen Rajju high. Within this, there are animals and plants everywhere where as Human beings are restricted to 2.5 continents of middle world. The beings inhabiting lower world are called Naraki (Hellish beings). Deva (roughly demi-gods) live in whole of the top and middle world and top three realms of lower world. Living beings are divided in fourteen classes (Jivasthana) : 1. fine beings with one sense. 2. Crude beings with one sense. 3. beings with two sense. 4. beings with three sense. 5. Beings with four sense. 6. beings with five sense without mind. 7. beings with five sense with a mind. These can be under-developed or developed which makes it a total of fourteen. Human beings get any form of existence and are the only ones which can attain salvation.
