Doctrine of soul.
The Jain philosophy believes in the existence of the 'soul'. Consciousness is an eternal characteristic of the soul.
There are two types of soul:
1. Mundane Soul
2. Liberated SoulMundane Soul is known as Baddha Jīva and Liberated Soul is known as Mukta Jīva.
In the former state, the soul has to undergo births and rebirths, in the latter one, the soul is free from all kinds of bondages. In the mundane state, there is both evolution and devolution, where as in the liberated soul there prevails infinite knowledge, infinite bliss and infinite power.
