It is based on right faith, right knowledge, right conduct, tempered with mercy. Jainism is not a theistic system in the sense of the belief in the existence of a God as the Creator and the Ruler of the world. The highest being in the Jain philosophy is a person and not a Being without attributes like the Brahman of the Vedanta. The Jain philosophy bases its doctrine on the absolute necessity of conquering the lower nature for the realisation of Truth. The Jains do not accept the authority of the Vedas.
Soul is that element which thinks, knows and feels.
It is the divine element in the living being. The true nature of the soul is right knowledge, right faith and right conduct. The soul is undergoing evolution and involution, so long as it is subject to transmigration. The combination of the Jiva and the Ajiva causes all diversities in this universe. Their interaction or interplay is the cause of the world-process or evolution.
