Baba Nand Singh Ji set forth a wonderful divine path, a unique culture and tradition through love and worship of Eternal Sri Guru Granth Sahib as living Guru Nanak. He realized through his unlimited and unique love for his master Guru Nanak Dev Ji. This all happened with the grace of his Great Divine Master Baba Harnam Singh Ji Maharaj after twelve years of continuous hard labour of Baba Nand Singh Ji to enshrine Guru Nanak Dev Ji deep in the holy heart. He experienced in his life that Sri Guru Nanak Sahib lives eternally. He responds and acknowledges physically the loving offerings of the faithful, the believers and the true devotees.
Baba Isher Singh Ji from childhood, served as the most devoted "Gurmukh Sewadar" (personal attendant) of Baba Nand Singh Ji Maharaj. He was fully committed to the service of Baba Nand Singh Ji Maharaj. He was attentive at all times and he never slept while on duty. Baba Nand Singh Ji often moved around through thick jungle and it was very difficult for any ordinary person to follow or keep pace with him. Baba Isher Singh never cared for his personal comfort and was ever ready to do whatever that was expected of him. Most of the time he was found barefooted in the service of Baba Ji.
When Baba Nand Singh Ji returned to his heavenly abode in
1943, Baba Isher Singh Ji could not bear the separation and
was in great grief for about seven years. He remained at Jhorara
Village. His eyes were usually full of tears most of the time.
Nanaksar became almost deserted without his master. Initially
Baba Isher Singh Ji had no desire to occupy Nanaksar as his
Head Quarters. But soon the devotees there began to complain
to Baba Ji regarding the misuse of the holy place by selfish
and irresponsible people. Furthermore the sacred system of
worship was being ignored and the devotees earnestly requested
him to restore the sanctity of the place. Baba Ji, acting
on the heavenly message from Baba Nand Singh Ji, moved to
Nanaksar together with the devotees.
Baba Amar Singh Ji was only eight years of age when his parents died. He started to visit Nanaksar Kalera with his paternal uncle. At the age of twelve he moved permanently to Nanaksar. Baba Amar Singh Ji followed Baba Isher Singh Ji to various parts of India for the purpose of preaching Sikhism, baptizing devotees and to spread the message of Universal Brotherhood. He visited places like Calcutta, Ranchi, Patna, Tata Nagar and Delhi. He also went to a village at the India-Bangladesh border at the request of some Sikhs camping there and baptized approximately 350 Bengalis.
Baba Amar Singh Ji stayed at Nanaksar Kaleran for nearly 14 years. During this period he spent nearly four and a half years receiving training in Kirtan. Upon the demise of Baba Isher Singh Ji, Baba Amar Singh Ji was sent to Barundi, the maternal village of Baba Isher Singh Ji to perform continuous singing of the Sikh holy hymns. From then onwards, Baba Amar Singh Ji started the "Parchar" - preaching of the Sikh religion, singing of the holy hymns, baptizing devotees and starting educational institutions in various parts of the world.
