Emphasizing secularism and rejecting sectarianism, the largest of all Trimandirs in India is located at Adalaj. Built with the purpose of breaking invisible walls between castes and religions, the temple aims to foster peace, unity and eternal joy while enriching people’s spiritual understanding. Spread across 40,175 square feet, this grand temple houses deities from Jainism, Shaivism, Vaishnavism and even other faiths. Every year, around 700,000 devotees visit this temple.
The Trimandir concept originated from Dada Bhagwan, a Jain spiritual leader and founder of Akram Vignan (science of spontaneous self-realization). Born Ambalal Muljibhai Patel on November 7, 1908, in Tarsali, Gujarat, Dada Bhagwan was a self-taught man with a spiritual inclination since childhood. After leaving formal education post-10th grade, he moved to Mumbai for business and worked as a contractor at Patel & Co., which maintained dry docks at Mumbai port. He claimed to have experienced self-realization in June 1958 while sitting on platform number 3 of Surat railway station. In the 1960s, he founded the Akram Vignan movement.
According to the Dada Bhagwan Foundation, Akram Vignan is a shortcut path to Self-Realization. Unlike traditional spiritual paths that demand renunciation of worldly life and strict self-discipline, 
Akram Vignan enables instant knowledge of the self (Atma Gnan) through the grace of an enlightened person. This process, known as Gnan Vidhi, reportedly imparts self-realization in just two hours. The essence of Akram Vignan is Gnan Bhakti—complete surrender to Simandhar Swami (a living Tirthankar in another realm) and his medium, Dada Bhagwan.
According to Jain tradition, Simandhar Swami is a living Tirthankar, currently residing in Mahavideh Kshetra, that is in another realm. Believed to have been born during the era of 17th Tirthankar Kunthunath and 18th Tirthankar Arhanath, Simandhar Swami’s physical form is said to be about 1,500 feet tall and his age is around 150,000 years. He is believed to live for another 125,000 years. King Dasharath is said to have taken initiation from him.
Trimandirs built by the Dada Bhagwan Foundation feature Simandhar Swami as the central deity, worshipped with deep devotion.
The Trimandir is considered a revolutionary religious concept. Its core idea is to bring together deities from Jain, Shaiva, Vaishnava and other faiths on a single platform, treated with equal reverence – to promote universal religious harmony. Dada Bhagwan taught, “People themselves have divided God and religion. Instead of choosing one deity, we should understand and practice the core principles of all religions. All deities guide us towards understanding the soul and attaining self-realization.”
Based on this philosophy, Trimandirs have been built in several places. 
One such temple lies about 10 km from Gandhinagar, on the Ahmedabad-Kalol highway, within a vast complex. Constructed in 2002 from white marble, this two-storey temple stands on 40,175 sq ft surrounded by lush greenery. A grand fountain, flanked by lion and elephant sculptures, adorns the entrance. True to the Trimandir style, the lower floor houses a 31,861 sq ft satsang hall, while the main temple is located on the upper floor.
Staircases on both sides lead to the upper level. An elevator is available at the rear for the elderly and those with mobility issues. Wheelchairs are also available.
Upon climbing the stairs, visitors are welcomed by lion sculptures. Intricate carvings embellish the temple’s pillars.
The massive gateway features Dwarpals (divine gatekeepers). The atmosphere inside the central hall is serene and uplifting, enhanced by a giant chandelier at the center of the 10,000 sq ft sabhamandap.
In the sanctum at the center is a 13-foot-tall marble idol of Simandhar Swami. To the left are temples of Chandrayana Yaksha and Panchaguli Devi. Smaller shrines house Lord Mahavir and Lord Parshvanath. Nearby are idols of Lord Ajitnath and Lord Rishabhdev. On the right is Chakreshwari Devi, with a large image of Dada Bhagwan and his Paduka (sacred footprints) in front. Further right is Vishnulok, containing idols of Shrinathji, Lord Krishna and Tirupati Balaji. To the left of Krishna’s idol is a cradle with Bal Krishna.
Outside the sanctum, the temples of Amba Mata and Bhadrakali Devi are located.
To the left of Simandhar Swami’s sanctum is Shivlok, with Nandi in front. Outside are idols of Hanuman and Ganesha, while the sanctum features a Shivalinga, with Goddess Parvati sculpted behind it. The temple complex also features shrines for Padmanabh Dev, Padmavati Devi and Sai Baba.
The temple remains open daily from 5 AM to 10 PM. Major festivals celebrated include Guru Purnima, Raksha Bandhan, Ganesh Chaturthi, Navratri, Paryushan Parva, Diwali and New Year. Weekly devotional programs are also held.
In the temple complex there is a museum and mini-theatre showcasing Dada Bhagwan’s life, with shows in Gujarati, Hindi and English. Inside the complex is Vignan Bhandar, a bookstore offering spiritual literature, audio CDs and DVDs on Akram Vignan in English, Hindi, German, Portuguese, Spanish and various Indian languages.
There is a modern Amba Health Centre offering allopathic, Ayurvedic and homeopathic treatments. For children, entertainment facilities are available, including 15-minute free theme shows at Bal Dunia.
