Answer

In the present Kalyug / Avasarpini of Bharat Kshetra, there is no living Arihant Bhagwan on Earth right now. The last Tirthankar in this era was Lord Mahavir Swami, and after nirvana He became a Siddha.

However, in Jain cosmology, living Tirthankaras do exist in Mahavideh Kshetra. So it is not correct to say that all Arihants everywhere are Siddhas.

Explanation

In Jain Dharma:

• Arihant = a soul that has destroyed the four ghati karmas and attained Keval Gyan, but still has a physical body.
• Siddha = a soul that has completely liberated and no longer has a body.

So:

• Before nirvana → Arihant
• After nirvana → Siddha

In our present time cycle for Bharat Kshetra, there is no Arihant Bhagwan among us. But in the broader Jain universe, there are always Tirthankaras in Mahavideh Kshetra who are living Arihants.

Spiritual Understanding

This teaches an important Jain truth:

• Liberation is possible.
• A soul can become omniscient while still embodied.
• Final freedom comes only after shedding the body and becoming a Siddha.

So, for us, the living path is to remember the Arihants, follow their teachings, and aim for liberation.

Takeaway

In our current Kalyug, no Arihant Bhagwan is present in Bharat Kshetra. All past Arihants here are now Siddhas. But living Arihants do exist in Mahavideh Kshetra according to Jain cosmology.
