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 that has existed since infinity with neither beginning nor end. Jain texts describe the shape of the universe as similar to a man standing with legs apart and arms 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.
Dravya (Jainism)
According to Jains, the Universe is made up of six simple and eternal substances called dravya which are broadly categorized under Jiva (Living Substances) and Ajiva (Non Living Substances) as follows:
Jīva (Living Substances)
Jīva i.e. Souls – Jīva exists as a reality, having a separate existence from the body that houses it. It is characterised by chetana (consciousness) and upayoga (knowledge and perception). Though the soul experiences both birth and death, it is neither really destroyed nor created. Decay and origin refer respectively to the disappearing of one state of soul and appearing of another state, these being merely the modes of the soul. Jiva are classified on bases of sense, so there are of 5 types: 1) with one sense (sparshendriya) 2) 2 senses (1st included and raasendriya) 3) 3 senses (1st 2 included and dharnendriya) 4) 4 senses (1st 3 included and chkshuendriya) 5) 5 senses (1st 4 included and shrotendriya)
Ajīva (Non-Living Substances)
Pudgala (Matter) – Matter is classified as solid, liquid, gaseous, energy, fine Karmic materials and extra-fine matter i.e. ultimate particles. Paramāṇu or ultimate particle is the basic building block of all matter. The Paramāṇu and Pudgala are permanent and indestructible. Matter combines and changes its modes but its basic qualities remain the same. According to Jainism, it cannot be created, nor destroyed.
