Shri Jirawala Dham – Coorg, Karnataka

• It is a Śvetāmbara Jain derāsar in the Coorg (Madikeri) area of Karnataka.
• Mūl nāyak: Shri Jirawala Pārshvanāth Bhagwān, white idol in padmāsan.
• This derāsar is made as a Jirawala Pārshvanāth temple similar to the famous Jirawala Tirth in Rajasthan, so devotees of Jirawala Parshvanath especially like to visit here.
• The place is in a very quiet, green hill area, good for doing sāmāyik, pratikraman, swādhyāy and peaceful dhyān.
• There is usually bhojanshalā and basic rooms for Jain sādharmik staying with śuddh Jain food (simple, non‑violence based).

Spiritually, visiting such a tirth / dham is mainly for:

• Darshan and vandan of Pārshvanāth Bhagwān
• Strengthening ahiṃsā, satya, aparigraha in our life
• Doing prārthanā for inner shanti and progress on the path of moksha, not for worldly miracles.
