In Jainism, not every temple is called a “tirth.”

1. Basic meanings

• Derāsar / Mandir – any Jain temple where Bhagwan’s idol is installed and daily pūjā is done.
• Tirth (Tīrth / Tirth‑kshetra) – a pilgrimage place, a holy site with special spiritual importance.

2. When is a temple called a “tirth”? A Jain temple or place is usually called a tirth when, for example:

• Some important event of a Tirthankar happened there

- e.g. janma (birth), dikshā (renunciation), keval‑jñān, or nirvāṇ

• Many sādhus, sādhvīs or shrāvaks have done strong tapas and sādhana there
• The place has become a big centre of pilgrimage for Jains over time
• There are usually multiple temples / caves / sangh facilities together (dharamshālā, bhojanalay, etc.)

Then we call it “tirth kshetra”, like:

• Shatrunjay tirth, Sammed Shikhar tirth, Girnar tirth, Nakoda tirth, etc.

3. Simple summary

• Small local temple in your town: mostly called derāsar / mandir.
• Big historic, spiritually powerful pilgrimage place: called “tirth” or “tirth‑kshetra.”

If you want, you can tell me the name of a place and I can say whether it is considered a tirth and why.
