“Tarak Dwar” is not a standard, fixed list in Jain scriptures. The phrase is sometimes used informally, so it can point to different things. People usually mean one of these:

• 52 Tonks (shrines) of Shatrunjaya (Palitana) — many devotees loosely say “52 dwar/doors,” though the canonical term is “52 tonks.”
• The Navkar Mantra as the “Taraka” (liberating) mantra — some ask for parts/names linked with it.
• Symbolic “doors” to moksha like the 14 Gunasthans (spiritual stages), sometimes explained as progressive gateways.
• Local temple gateways or yatra-circuits that devotees call “tarak dwar” in regional usage.

If you tell me which of the above you mean (for example “52 tonks of Shatrunjaya” or “14 gunasthans”), I will list the exact names with brief, authentic Jain explanations.
