Here is the clear, simple difference between Arihant and Siddha in Jain Dharma:
1. State of the soul
- A soul who has destroyed all
ghāti karmas (knowledge‑obscuring, perception‑obscuring, deluding, and obstructing karmas).
- Has attained
keval jnān (infinite knowledge) and
keval darshan (infinite perception).
- Still has a
physical body and the remaining
aghāti karmas (name, status, feeling, lifespan).
- Therefore, still present in the world and visible.
- A soul that has destroyed
all eight karmas, both
ghāti and
aghāti.
- Has no body, no form, no rebirth.
- Resides forever at the top of the universe in
Siddha‑śilā, in pure infinite
knowledge, perception, bliss and energy.
2. Role for us
- Is a
living, omniscient teacher.
- Shows the
path of liberation, establishes or supports Jain
sangh (especially Tirthankars).
- We can receive teachings (śāsan) from them while they are in the body.
- Has already completed the journey.
- Does not teach now; simply remains in
perfect, motionless, unattached bliss.
- Is our
final ideal and goal.
3. Relation between the two
- Every Arihant eventually becomes a Siddha at the time of nirvāṇa (when the body is left and the remaining aghāti karmas are destroyed).
- So:
-
Arihant = liberated-in-knowledge, still embodied.
-
Siddha = fully liberated, disembodied, eternal.4. In worship (Namokār Mantra)
- We say “Namo Arihantāṇam” first and “Namo Siddhāṇam” second.
- Reason:
-
Siddha is the highest state.
- But
Arihant is the one who
shows us the path to reach that state, so in practical worship they are saluted first.
5. Digambar and Shwetambar view
- Both traditions agree on the core difference:
- Arihant = omniscient, embodied.
- Siddha = completely liberated, bodiless in Siddha‑śilā.
- Some details (e.g. about women attaining Siddhahood, or exact cosmological descriptions) differ between Digambar and Shwetambar, but this basic distinction is the same.
