The idol installed in this temple is nearly 2800 years old. It is made of Emeralds. Only a direct observer who has actually seen the Lord can make the thirteen and a half ft. high idol of Bhagawan Pashvanath . The colour of the idol is the actual colour of the Lord. Sculptors and idol specialists  are of the opinion that the gem – stone out of which the idol is made is more than two thousand years old. It is believed that the idol was made by gods.  This idol was formerly installed in the temple in the city of Ahichattra. As time passed by, people came to know about the value of this idol. In greed, many people wanted to destroy the idol. The presiding deity protected the idol. A Jain Acharya heard of this and by virtue of his penance, he called Dharanendradev and asked him to make the idol of stone  so that any greedy person  may not break the idol. Later on, this idol was brought to Parasnagar and installed there. King Ajitsen built a beautiful temple for the Lord and worshipped the Lord.  He was childless. He was blessed by a child. In Vikram Samvat 1624, this temple was renovated by the preachings of Shri Abhaydevsuri. Parasnagar became Nageshwar and hence the Lord came to be known as Nageshwar Parshwanath. As time flew, the  Pujaribaba of that place became the owners of the idol. Upadhayay Shri Dharmasagarji Maharaj, came to know that the idol known as ‘Nagbaba’ in the unhel village of Rajasthan was in fact an ancient Jain Swetamber idol of Bhagawan Nageshvar Parshwanath. It was in the possession of non-Jains. By his strenuous efforts, the idol was returned to the Jains through court order. The idol was re-installed by Shri Ahbaysagarji ganivarya and made fit for worship by doing 18 Abhishek Pooja. Since the year 1970 of the Vikram era, the temple is under complete ownership of Jains. All the credit for the success goes to bright intelligence, hard efforts, generosity, devotion and oratory of Shri Abhaysagarji Maharaj Saheb. Many rich merchants also extended their praiseworthy co-operation towards the development of the tirth. The idol of Nageshvar Parshwanath was reinstalled for worship in Vikram Samvat 2037.
