Shri Swami Swarupanand Ji Maharaj, also known as "Shri Nangli Niwasi Bhagwaan Ji", "Hari Har Baba", "Sadhgurudev Ji", and "Second Guru", was an Indian Guru of Shri Paramhans Advait Mat lineage. He was born as Shri Beli Ram Ji in the village of Teri in the Kohat district of India (now in Pakistan) in 1884. He was initiated into the sanyasas by Shri Paramhans Swami Advaitanand Ji in the early 1900s and was named Shri Swami Swarupanand Ji.

Under the guidance of his master, Swami Swarupanand Ji created an order of sanyasis in northern India and founded several centers to spread his master's teachings. Shri Paramhans Swami Advaitanand Ji instructed him to meditate in Agra to preserve his spiritual power for future use as a spiritual reformer. For 14 years, Swami Swarupanand Ji meditated in a gufa, a tight cave under a neem tree, where he ate only boiled neem leaves, reducing his body to a skeleton. A temple was later built around the cave in Agra, called Tapobhoomi.

After the death of his master, Shri Paramhans Swami Advaitanand Ji, Swami Swarupanand Ji was declared as his spiritual successor. He had more than 10,000 followers and established over 300 ashrams in northern India at the time of his death. In 1935, he announced his decision to leave Punjab and settle in Uttar Pradesh, causing grief among his followers. He visited Delhi for the last time in 1936 before moving to Nangli village, near Meerut. He passed away a year later in Nangli Sahib, where his samadhi (grave) is located.

Shri Swami Swarupanand Ji Maharaj had followers from all religions, and he believed that a faqir (a Muslim ascetic) had no particular religion but was common to all. One of his disciples, Shri Paramhans Swami Ramanand Satyarthi Ji Maharaj, established the Paramhans Satyarthi Mission, which is a spiritual institute that continues to spread Swami Swarupanand Ji Maharaj's teachings. Another disciple, Hans Ji Maharaj, established the Divine Light Mission.

Although some confusion exists, Shri Swami Swarupanand Ji Maharaj is not the same as Anand Swarup of the Radha Soami lineage.     

Shri Swami Swarupanand Ji Maharaj, also known as Shri Nangli Niwasi Bhagwaan Ji, Hari Har Baba, Sadhgurudev Ji, and Second Guru, was an Indian guru of the Shri Paramhans Advait Mat lineage. He dedicated his life to spreading his master's teachings and establishing ashrams and spiritual centers throughout northern India.

Swami Swarupanand Ji founded over 300 ashrams and centers across northern India, where he taught his disciples and followers about the importance of self-realization and spiritual development. His teachings emphasized the unity of all religions and emphasized the importance of service to others, especially the less fortunate.

One of Swami Swarupanand Ji's most significant contributions to the spiritual world was his creation of an order of sanyasis, or wandering ascetics, in northern India. He established training centers where young men could receive spiritual and philosophical education and guidance from senior sanyasis. This order of sanyasis is still active today, and its members continue to spread Swami Swarupanand Ji's teachings throughout India.

Another important contribution of Swami Swarupanand Ji was the construction of a temple around the cave in Agra, where he meditated for 14 years. The temple, called Tapobhoomi, is now a significant pilgrimage site and a center of spiritual activity.

Swami Swarupanand Ji's legacy continues today through the Paramhans Satyarthi Mission, which was founded by one of his disciples, Shri Paramhans Swami Ramanand Satyarthi Ji Maharaj. The mission is a spiritual institute dedicated to spreading Swami Swarupanand Ji's teachings and promoting spiritual development and service to others.

In summary, Shri Swami Swarupanand Ji Maharaj's work focused on spreading spiritual teachings, establishing ashrams and centers, creating an order of sanyasis, and promoting unity among religions. His teachings continue to inspire and guide people today, and his legacy lives on through the various organizations and centers that he established.
