He had also been the trustee of many temples and President of South Arcot District Hindu temple development Committee, Zilla Board. He visited Cuddalore Prison as an unofficial visitor and assisted in various ways for the rehabilitation of the inmates there. He was a member of Cosmopolitan Club Cuddalore and president of Nellikuppam Panchayat Board for more than 20 years. The Nellikuppam sugar mill was started by him when he was the Nellikuppam Presented. He was fully involved in building the bridge across the Bhuvanagiri Vellar river at his own expense and obtained permission from the government to build the bridge for the public. The British government arrested some of  the peoples of Vembur Paraiyar and Piramalai Kallar under the Criminal Tribes Act and formed the Aziz Nagar settlement in the Southern District and jailed these people in this settlement. The oppressed people in the Aziz Nagar settlement were without even basic facilities and food. Jambulinga Mudaliar visited the aziz nagar settlement unofficially and provided food and basic necessities to the affected people there. Jambulinga Mudaliar vehemently opposed the Criminal Tribes Act and only the Criminal Tribes Act against the Vanniyar Padayachi of the South Arcot was repealed. He approached the government in several ways to build the Salem to Cuddalore railway line, but the government could only give permission to build the Salem-Cuddalore railway line if there were at least 50 people daily on the Cuddalore-Salem bus service for a year. Jambulinga Mudaliar, who believed that the two districts would prosper if the Salem-Cuddalore railway line was built, finally got the Salem-Cuddalore railway project by after having Jambulinga Mudaliar's 50 servants travel on buses on the Salem-Cuddalore route for a year at Mudaliar's own expense. Foundation of Neyveli Lignite Corporation
When Jambulinga Mudaliar dug a new well for water on his own Neyveli village farm land, the black liquid was mixed with water. He sent it to the attention of the then British Government Geography Department but the Government did not look into it. He then carried out research at his own expense and discovered the presence of coal. After the independence of India, he approached the then Madras Chief Minister Rajaji and explained the existence of this coal. The government, however, did not investigate it. K. Kamaraj then approached Chief Minister  and explained to him that he had met Nehru, the then Prime Minister of India, through Kamaraj and explained to him. The central government has said it cannot help the company as it needed Rs 150 crore to start the company. Aware of this, Jambulingam Mudaliar announced that he would donate 620 acres of land required for the establishment of the Neyveli Coal Mining Company to the Kamaraj-led State Government. The Kamaraj-led state government set up the Neyveli Lignite Corporation Limited without the help of the central government as the land required for the company was donated by Jambulingam Mudaliar. The 620 acres of land donated by Jambulingam Mudaliar to Neyveli Lignite Corporation (NLC) is worth Rs 2,500 crore today. Today, 90 percent of South India's electricity needs is generated by thermal power plants. All the brown coal required for these South Indian thermal power plants is sourced from the Neyveli lignite Corporation. The Neyveli lignite Corporation and Thermal Power Station employ 50,000 workers. The company has a turnover of several lakh crores of rupees. Honors
