In Jainism, Nav Tatva (also spelled Nava Tattva) refers to the "Nine Fundamental Principles" that explain the path of liberation and the nature of existence. Understanding these helps a spiritual seeker progress on the path of moksha (liberation). The nine tattvas are:

1. Jiva (soul) – The living, conscious substance; the soul or atman.
2. Ajiva (non-soul) – The non-living substances; everything that is not soul (matter, time, space, etc.).
3. Punya (merit) – The result of good karma, which leads to pleasant experiences.
4. Papa (sin) – The result of bad karma, which leads to suffering.
5. Asrava (influx) – The inflow of karmic particles to the soul due to activities of mind, speech, and body.
6. Bandha (bondage) – The binding of karmic particles to the soul.
7. Samvara (stoppage) – The process of stopping the influx of new karma.
8. Nirjara (shedding) – The process of removing existing karmas from the soul.
9. Moksha (liberation) – The ultimate goal: liberation of the soul from all karmic bondage.
