On Shatrunjay (Palitana), the main temple (Chaumukhji) on the top of the hill has the Mulnayak Bhagwan Adinath (Rishabhdev) as the principal idol.

Outside the main temple / main tunk you will generally see:

1. Small Jinalayas (deris) and foot‑prints (charan)

- Foot‑prints of: - Bhagwan Adinath - Other Tirthankars - Great shravaks and acharyas - These are places for vandana and smaran, but the main darshan focus remains the Mulnayak Bhagwan inside the main temple. ( jainknowledge.com)

1. Idols of Devi–Devta

- Especially Padmavatidevi and other shasan dev–devis in nearby temples. - These are shasan‑devata – helpers in dharma – not equal to Tirthankars. - Jains bow here for protection in dharma, but do not treat them as Tirthankars. ( jainknowledge.com)

1. Temples and models at the base (Jaytaleti)

- Temples like Samavasaran Mandir, Jambu‑Dweep model, mini‑Shatrunjay, etc. - There is also a standing idol of Adinath Bhagwan in deep meditation (for those who cannot climb the full hill, they can still do Shatrunjay bhakti here). ( jainknowledge.com)

1. Important point about maryada

- Inside the main temple area, mobiles and photography are generally not allowed, to keep shanti, dhyan and shraddha during darshan and puja. ( jainknowledge.com)

So, the “Jain idols outside the main temple” in Palitana are mostly:

• Small Jinalayas of Tirthankars
• Charan (foot‑prints) of Tirthankars and great souls
• Devi–devta murtis like Padmavatidevi
