According to Jain tradition, Palitana is one of the most important pilgrimage sites, especially for the Svetambara sect. It is also known by other names in ancient texts, such as Padliptapur, Padliptapattan, and Pundarikgiri. The term "Nagarjun" is not directly associated with Jain historical references to Palitana. However, Jain scriptures and ancient literature mention Shatrunjaya as the hill on which Palitana temples are situated.

About your second question regarding "the other Nagri": If you are referring to another significant Jain pilgrimage city (Tirtha) with "Nagri" in its name, Sammet Shikharji (also called Parasnath), though not commonly called "Nagri," is considered very important. If you are asking about ancient names, Champanagari (Champapuri) and Rajgir (Rajgriha Nagri) are also significant in Jainism.

To summarize:

• Palitana: Also known as Padliptapur, Padliptapattan, Pundarikgiri, and is on Shatrunjaya hill.
• Another famous Jain city: Champanagari (Champapuri), Rajgriha Nagri, or Girnar (Revatgiri Nagri).

If you provide more context about "Nagarjun" or "Nagri," I can offer a more specific Jain reference.
