Answer

In Jain Dharma, Arihant Bhagwant means a soul who has destroyed the four ghāti karmas and attained Keval Jñān.

There are two important stages:

• Arihant — living omniscient Bhagwant, still present in the body.
• Siddha — liberated soul who has attained moksha after leaving the body.

So yes, Arihant Bhagwant has not yet attained Siddha state, because Arihant still has a body. After the remaining karmas are destroyed and the body ends, the Arihant becomes Siddha Bhagwant.

Explanation

In Jainism:

• Arihant Bhagwant has destroyed anger, ego, deceit, greed, and all knowledge-obscuring karmas.
• But some non-destructive karmas remain, such as body-related karma.
• Because of this, Arihant still lives in the world with a physical body.
• When those remaining karmas finish, Arihant attains moksha and becomes Siddha.

Spiritual Understanding

Arihant Bhagwant is worshipped because Arihant shows the path to liberation. Siddha Bhagwant is the final liberated state. Both are supreme, but their states are different:

• Arihant = liberated in inner qualities, but still embodied.
• Siddha = completely liberated, bodiless, at Siddhashila.

Takeaway

Arihant is not yet Siddha because Arihant still has a body. After nirvāṇa, Arihant becomes Siddha and attains moksha.
