For 2025, I do not have an authentic, published list of which Jain Shwetambar Terapanth sadhus or sadhvis actually did Chaturmas in Chennai.

In Terapanth, the detailed Chaturmas-sthayak (who stayed where) for each year is usually finalized and circulated by:

• Local Terapanth Sabha / Sangh
• Terapanth Bhavan or Upashray in that city
• Official Terapanth announcements and local notice boards / WhatsApp groups

Because this is very location-specific and can change even late due to vihār (travel) and arrangements, the most accurate way to know “Chennai mein 2025 mein kaunse Terapanth ke sadhu/sadhvi ka Chaturmas hua?” is:

1. Contact the local Terapanth Sabha / Terapanth Bhavan in Chennai
2. Ask at the nearest Terapanth Upashray / Jain Sangh office
3. Check if they have the 2025 Chaturmas pamphlet or circular (often printed and also shared as PDF/WhatsApp)

There is a related discussion already on JainKnowledge about Terapanth Chaturmas 2025 in Chennai which explains this point; you can read it here:

Beyond this, giving a specific name without proper Terapanth records would be inaccurate, so it is better to confirm directly from the Chennai Terapanth Sangh.
