Answer

In Jain Dharma, Arihant and Siddha are both liberated or spiritually perfected souls, but they are at different stages.

• Arihant: A soul who has destroyed the four destructive karmas and has attained Keval Gyan while still living in the body.
• Siddha: A completely liberated soul who has destroyed all eight karmas, left the body, and resides forever at Siddha Shila.

So, an Arihant is a living omniscient being, while a Siddha is a bodiless liberated soul.

Difference Between Arihant and Siddha

Stages: From Ordinary Soul to Siddha

Jain Dharma explains spiritual progress through the 14 Gunasthanas — fourteen stages of spiritual development.

1. Mithyatva Gunasthana – Wrong belief; the soul does not have right faith.
2. Sasvadana – A very brief mixed condition after falling from right faith.
3. Misra – Mixed belief; neither fully right nor fully wrong.
4. Avirata Samyagdrishti – Right faith, but no vows yet.
5. Deshvirata – Partial vows, usually the stage of serious householders.
6. Pramatta Samyata – Monkhood with full vows, but still with some carelessness.
7. Apramatta Samyata – Monkhood without carelessness.
8. Apurva Karana – Very advanced purification; new spiritual development.
9. Anivritti Karana – Further advanced purity.
10. Sukshma Samparaya – Only very subtle greed remains.
11. Upashanta Moha – Delusion is suppressed, not destroyed.
12. Kshina Moha – Delusion is destroyed.
13. Sayogi Kevali – Arihant stage; Keval Gyan attained while bodily activities remain.
14. Ayogi Kevali – Final moment before liberation; all activities stop, then the soul becomes Siddha.

How Arihant Stage Is Attained

A soul becomes an Arihant when it reaches the 13th Gunasthana, called Sayogi Kevali.

This happens when the soul destroys the four destructive karmas:

• Gyanavarniya Karma – Knowledge-obscuring karma
• Darshanavarniya Karma – Perception-obscuring karma
• Mohaniya Karma – Deluding karma
• Antaraya Karma – Obstructing karma

When these karmas are destroyed, the soul attains:

• Infinite knowledge
• Infinite perception
• Perfect conduct
• Complete freedom from passions

How Siddha Stage Is Attained

Arihant becomes Siddha after the end of bodily life, when the remaining four non-destructive karmas are also destroyed:

• Vedaniya Karma – Feeling-producing karma
• Nama Karma – Body-making karma
• Gotra Karma – Status-determining karma
• Ayushya Karma – Lifespan-determining karma

After all eight karmas are destroyed, the soul rises to the top of the universe, called Siddha Shila, and remains there forever in its pure state.

Spiritual Understanding

The path from ordinary soul to Siddha is based on the Ratnatraya, the Three Jewels of Jain Dharma:

• Samyak Darshan – Right faith
• Samyak Gyan – Right knowledge
• Samyak Charitra – Right conduct

To progress spiritually, one practices:

• Ahimsa — non-violence
• Satya — truthfulness
• Achaurya — non-stealing
• Brahmacharya — celibacy or purity
• Aparigraha — non-attachment
• Tapasya — austerity
• Meditation and self-discipline
• Control of passions like anger, ego, deceit, and greed

Takeaway

Arihant is the perfected soul still living with a body after attaining Keval Gyan. Siddha is the completely liberated soul without body, free from all karmas forever.

The journey to both is through right faith, right knowledge, right conduct, vows, self-control, destruction of passions, and complete purification of the soul.
