“Arihant Bhagwan” is a very important term in Jain Dharma.

Meaning of “Arihant”

• Ari = enemies
• Hant = destroyer

So Arihant means “the destroyer of inner enemies”.

These enemies are:

• krodh (anger)
• maan (pride)
• māyā (deceit)
• lobh (greed)

and all karmas that cover the soul’s pure nature.

Who is Arihant Bhagwan?

Arihant Bhagwan is:

• A living kevali (one who has attained Keval Jnan – perfect knowledge)
• Has destroyed all ghātiya karmas (knowledge‑covering, perception‑covering, deluding, energy‑obstructing karmas)
• Still has a physical body, so is present in some loka (like Mahavideh Kshetra)
• Is vitarag – completely free from attachment and hatred
• Is a Tirthankar if he also establishes the Jain Sangh (fourfold order)

After the end of that life, Arihant Bhagwan becomes Siddha Bhagwan (liberated soul) in Siddha Shila.

Examples (for understanding)

• In our present time (Bharat Kshetra), Bhagwan Mahavir was Arihant Bhagwan when he attained Keval Jnan. After nirvana, he is Siddha.
• In Mahavideh Kshetra, there are living Tirthankar Arihants like Simandhar Swami (according to Jain tradition).

Short summary

Arihant Bhagwan = the soul who, by destroying inner enemies and ghātiya karmas, has attained Keval Jnan and is completely vitarag, but still has a body.

If you tell me what exactly you want (meaning, list of Tirthankars, or difference between Arihant and Siddha), I can explain that part in more detail.
