Due to the commissioning of Railway line throughout this district, people belonging to the Bengali Community came and settled here at Haflong for businesses as well as for the purpose of commissioning of Railway line. Amongst themselves, some people were there who were deeply inspired by the Ideology Sri Ramakrishna-Sarada devi and Swami Vivekananda. They began to feel the necessity to form an association to serve and propagate the holy teachings of Thakur-Maa-Swamiji.

They were motivated and inspired in the formation of such association by some visiting Monks of the Ramakrishna Orders from the Kumilla and Sylhet District of undivided India.  

During 1945, Rev. Swami Ajoyanandaji Maharaj paid his visit to Haflong from Kumilla and stayed there for over a month. He used to deliver discourse covering various aspects of the teaching of Thakur, Maa and Swamiji at the Local Jagannath Bari Premises as well as at the residences of some of the ardent devotees, during his prolonged stay at Haflong. that Rev Maharaj is one of the prominent personalities who had motivated the local devotees in the formation of an Association to which would help them to practice and propagate the holy teachings of Thakur, Maa and Swamiji.

Some prominent personalities like Late Benode Behari Chakraborty, Late Kamini Kumar Sharma, Late Girindra Bala Dasi, Late Bipon Chanda Deb and others had taken the pain in the formation of that Association and accordingly, on 9 December, 1945, an Association in the name and style of “SEVASHARAM” was formed. The Activities of this “SEVASHARAM” had commenced at the Local Jagannath Bari Premises from the beginning of 1946. Immediately, a Library, containing various books on the Life and Teachings of the Holi Trios and other pertinent books and journals, was set up with meager donations of the devotees.

Primarily, it was intended to form the Association in the name & style of “RAMAKRISHNA SEVASHARAM”. But, the then local British Administration did not approve the nomenclature, and hence, the name of the Association was renamed as “SEVASHARAM”.

In course of time, with the attainment of Independence in the year 1947, the name of the Association was again renamed as “RAMAKRISHNA SEVASHARAM” in the year 1951. Later, in the same year, i.e., in the year 1951, the nomenclature of the Association was finally renamed as “SRI RAMAKRISHNA SEVA SAMITY”.

The Activities of the Samity had been carried out from the Local Jagannath Bari Premises wef 9 December 1945 to 1951 up till the allotment of 22 Bigha and 8 Katha of Land to the Samity by the Local Administration.

The allotted land was a hillock with innumerable trees and shrubs. The gigantic tasks of leveling the Hill Tops for the establishment of a Prayer Hall and a Student Hostel were the utter concern of the devotees at that period of time. But people cutting across different caste, creed and communities, joined hand together, rendered their invaluable “Shram Dan” for clearing and leveling the hill top. A large numbers of employees from Railways, 9^th Punjab Regiment, 63 Dogra Regiment, Orissa Military Police, Assam Police Battalion and others also rendered their invaluable “Shram Dan” for the above purpose.

In the Year 1955, the construction of the “CHATRABAS” (tin-shed house) was accomplished out of the donations raised from the devotees since, 1947. On 22 February, 1956, this “CHATRABAS” was inaugurated. A second Chatrabas was constructed during the early part of 60’s.

In the year 1959, the construction of the GARVA MANDIR was ceremonially commenced with the donations as raised from the devotees since, 1947. And the Garva Mandir was formally inaugurated on 13 October, 1963, on the auspicious occasion of 100^th Birth Anniversary of Swami Vivekananda. Several Monks from Belur Math had graced that auspicious occasion. The prominent among them were Swami Japanandaji Maharaj, Swami Bhabyanandaji Maharaj, Swami Pranabatmanandaji Maharaj, Swami Sohananandaji Maharaj, Swami Kalyanandaji Maharaj (Vedanta Math), Swami Jibendu Maharaj and Privrajika Shradhaprana Mataji (Sarada Math).

During 50s Rev Swami Chandikanandaji Maharaj had paid his august visits on several occasion to this Ashrama. Maharajji took the pain in teaching the devotional songs to the local devotees. Swami Somyanandaji Maharaj was also instrumental in teaching Bhajans etc. to the devotees.

In the year 1954, with the inspiration of Swami Chandikanandaji Maharaj, “The Sarada Sangha” was formed with the local lady devotees. Every week, the members of the Sarada Samity used to arrange Path O Alochona in the house of some of the devotees.

In the year 1970, the name of the “The Sarada Sangha” has been changed to “The Sarada Samity” as per the guidelines of Ramakrishna Math and Mission. Every Sunday, Members of the Sarada Samity usually gather in the evening, for Patha, Alochana etc.

This Ashrama to an Affiliated Branch Centre of Ramakrishna math & Mission, it has also been a member of Uttar Purbanchal Bhav Prachar Parisad-III and this Ashram had successfully organized Parisad’s Annual/Half-Yearly for two times.

In the year 1970, with the active initiative of some the lady devotees and with the direct inspiration of Rev Satyen Maharaj, “Vivekananda Sishu Sangha” was formed. Later on, with the demise of some the active lady devotees, the activities of the “Vivekananda Sishu Sangha” have diminished considerably.

This Samity/Ashrama has been blessed by the visits of some of our illustrious Presidents of our Order starting with Revered Swami Madhavanandaji in 1940. Several other Presidents and Vice Presidents, Revered Swami Bhuteshanandaji, Swami Gahananandaji and in recent times, Revered Swami Vagishanandaji, Swami Shivamayanandaji, Swami Girishanandaji, visited this Centre, some of them multiple times.

Since its inception in 1945, a Library cum book sell counter has been functional as on date.

The devotion of the founders of the Ashrama and their service to the local masses could set up a rich tradition to follow for their descending generations. Deriving inspiration from the predecessors, the later generations and some other dedicated followers, during the later part of the 70's and early 80's, had taken the initiative to formalize the present set up of this Ashrama. Their initiative resulted in to the construction of the Mandir Prayer Hall, by further leveling the hill top and the construction of the MONKS’ GUEST HOUSE for the visiting monks. The Managing Committee of the Ashrama persuaded the Public Works Department to construct Pucca Approach Road up to the Ashrama Campus. These advancements created a new enthusiasm and the successive Managing Committees of the Ashrama continuously took up various developmental initiatives to bring it up in its present shape. The "PANCHAVATI", a sacred place earmarked for prayer and meditation had been constructed.

 In course of time, the new "Students Home-cum-Library" and the "Cutural Hall” came up. Every one of the succeeding generations representing various Managing Committees tried their utmost to develop and uphold the name and fame of this Ashrama. 

 In the year 2023 a two-storied MONKS’ GUEST HOUSE cum HOSTEL BUILDING has been constructed with the Aid of Govt. of Assam. The Hostel Building can now accommodate 50(Fifty) Students.

Since inception, the strength of this Ashrama has always been the lady devotees, the members of Sarada Samity and other dedicated lady disciples. They are the firm pillars of all Ashrama activities; they have always performed the Puja Activities of the Ashrama and Sadhu Seva with utmost devotion and dedication. It is for their active participation only that we could meticulously accomplish these activities.

Despite having rendered commendable seva related activities, the Ashrama has been ill equipped with the power of motivating and convincing the local tribal people in the process of bringing them to the Ramakrishna Bhabaandolon. They could not be properly motivated and educated with the teachings of the Math and Mission. 

With that aim in view, and in order to properly motivate and educate the tribal masses with the teachings of the Math and Mission by some experienced monastic order. Since the inception of this Ashrama in 1945, each and every Managing Committee of the Ashrama, while realizing the ample opportunity to practice and propagate the teachings of the Holy Trio in this area had tried their level best to persuade the Ramakrishna Math and Mission, Belur, to take over this Ashrama as their full-fledged Centre or a Sub-Centre of a nearby Centre with some monastic support.

During April, 2023, The Ashrama was declared as the Sub-Centre of Ramakrishna Mission Sevashram, Silchar.  Swami Pranarupanandaji Maharaj was sent to this Ashrama to monitor the process of transferring the Movable and immovable assets of Sri Ramakrishna Seva Samity, Haflong in favour of Ramakrishna Math and Mission, Belur Math. Swami Ganadhisanandaji Maharaj, Secretary, Ramakrishna Mission Sevashram, Silchar was made the In-charge of the Samity.

On 10^th of May, 2024, has finally recognized this Ashrama as the full-fledged Branch Centre of Ramakrishna Math and Mission, Belur math. The nomenclature has now been changed as “RAMAKRISHNA MISSION, HAFLONG”. On this date, Swami Amiteshanandaji Maharaj has taken over the charge of “RAMAKRISHNA MISSION, HAFLONG” as the Secretary of “RAMAKRISHNA MISSION, HAFLONG”.
