“Sahastrafana Parshwanath” means the idol of Bhagwan Parshwanath with one thousand serpent hoods (sahastra = thousand, fana = hoods).

In Jain tradition:

• This is the same 23rd Tirthankar, Bhagwan Parshwanath, shown with a very special nag-śeṣ (serpent canopy).
• Instead of the more common 7 or 9 hoods, here the śeṣ-nāg spreads into 1000 tiny hoods forming a grand umbrella over Bhagwan.
• The idol is usually:

- In Padmāsan or Khāḍgāsan/Kaussagga posture - With Dharanendra (Nagraj) and Padmāvatī Devī associated in the parikar (background carving) - Often made from a single stone with extremely fine carving

Spiritually, Sahastrafana form reminds us of:

• Supreme protection of a Tirthankar’s tapas (like when Dharanendra protected Parshwanath in the storm)
• Anant (innumerable) souls taking refuge in his teachings, symbolised through countless hoods
• Deep kṣamā, karuṇā and ahiṁsā embodied by Parshwanath Bhagwan

Famous Sahastrafana Parshwanath idols include:

• Surat (Gopipura) – Sahastrafana Parshwanath Jain Mandir – very well‑known for its beautifully carved khaḍgāsan idol with thousand hoods and detailed parikar. You can read its traditional story and details here

• Lodrava (near Jaisalmer) – black idol in Padmāsan with sahastrafana canopy, also very famous in Śvetāmbara tradition. More about Lodrava Parshwanath here
