Known as the Sikh religious personality, reverent Baba Thakur Singh was born in 1915 A.D. in village Ichogil, district Lahore (Pakistan). The name of his father was reverent Baba Bahadur Singh and that of his mother was Bibi Prem Kaur. Baba Bahadur Singh and Mata Prem Kaur both were baptized perfect in reciting Nitnem and had full faith in the home of the Satguru. After the partition they migrated to India and made village Sadarwala near Makhu, district Ferozepur their permanent residence.
Right from the beginning i.e. from childhood, Baba Ji is self-absorbed and perfect in meditation, benevolent, benign, peaceful, deeply engrossed in reciting the Sikh religious scriptures and have perfect faith in Satguru. Right from the very young age he would not indulge himself in outward games and never wasted his time in idle prattle. When he grew up he started helping his parents in the daily routine work but his mind would always be occupied with the name of the Satguru. Right from his childhood he believed in eating after its distribution amongst others as he saw the Satguru in everybody. While always in the deep meditation of the Satguru, he wished he should have company of some holy men, who must have been baptized with holy nectar, so that he should spend rest of his life in that manner.
When he came to know through the Sangat that at this time, Giani Gurbachan Singh Ji Khalsa is propagating the Sikh religion along with his Jatha, Baba Ji set out from his house towards Bhindar Kalan district Moga. He was told by the Sangat that Baba Gurbachan Singh Ji Khalsa was a great Sikh scholar and was enjoying the blessings of Sri Guru Gobind Singh. Baba Ji was baptized by the five beloved Sikhs (Panj Piaras) with the holy nectar. Baba Gurbachan Singh Khalsa came to know the state of mind of Baba Thakur Singh and handed him over the service of the community kitchen or Guru Ka Langar. Baba Ji discharged this duty whole-heartedly. After the service of two and half a year Baba Thakur Singh was admitted to the Jatha permanently and was given the knowledge of ultimate truth or theosophy.
Till the day his soul departed to the Sachkhand, Baba Thakur Singh was his permanent attendant for 22 years. Being happy on his selfless service, the perfect Saint, Sant Baba Gurbachan Singh showered his blessings on him and gave him exalted spiritual position. His words are, "The time will come when you will be entrusted with great tasks and service." After he left for his heavenly abode Baba Thakur Singh was with Sant Kartar Singh Bhindranwale for eight years and served the community kitchen i.e. Guru Ka Langar with great devotion. He was highly regarded by the Saint. He was consulted before taking any important decision. That was a time when the Sikh Panth was facing the crisis. There were all out efforts to cow down the Sikhs. Sant Kartar Singh Khalsa took out 37 long processions which awakened the sleeping Sikhs. It was at that time that Sant Ji announced amongst the Sangat, "If the government dares to arrest me then Baba Thakur Singh will take the responsibility of the Taksal into his hands. He may entrust the service whomsoever he likes."
When Sant Kartar Singh Ji Khalsa Bhindranwale left for his heavenly abode, Baba Thakur Singh appointed Sant Jarnail Singh Khalsa as the chief of the Damdami Taksal. The Sant would always follow the advice of Baba Thakur Singh.
In July 1982, when Sant Jarnail Singh Ji Khalsa started the Dharam Yudh Morcha from Amritsar for the independence of the Sikh Qaum (nation), the management of Gurdwara Gurdarshan Parkash Mehta Chowkwas given to Baba Thakur Singh. In June 1984, the government attacked the Golden Temple Amritsar and thousands of Sikhs were martyred. After the attack the Sant left for some unknown place. In his absence, the service of the Damdami Taksal and the de facto authority of the Sikh Panth was given to Baba Thakur Singh. Baba Ji is discharging this duty with great courage and farsightedness. He has been entrusted with this task at a critical juncture and he is leading the Sikh Qaum like an enlightened religious leader. The Sikh Qaum (nation) has accepted him as its religious chief and have rallied round him.
He is carrying forward the preachings of the Damdami Taksal. He goes to different places in India and abroad in religious functions. He has baptized thousands of people with the holy nectar and has given their hand to the Satguru. He has been continuing the teachings and training in Shabd Kirtan of the Jatha. He has helped the Sikhs who have been arrested and wrongly put into jails in the legal matters. He is looking after the families of those who have been martyred.
Making a very big contribution towards the Sikh Panth he has survived the custom of Sarbat Khalsa. He has discharged the duty of the Kar Sewa of Sri Akal Takht Sahib in an intelligent and hard working manner. He has served innumerable Gurdwaras and is still serving. He has completed the Kar Sewa of Gurdwara Shaheed Ganj (B-Block) Amritsar. He has constructed a Gurdwara on the Kiratpur Road for the convenience of the Sangat. He has started Khalsa Academy (affiliated with C.B.S.E., New Delhi) and a hospital in the memory of Sant Giani Kartar Singh Ji Khalsa at Mehta.
Sant Baba Thakur Singh is the spiritual backbone of the Sikh world. He is the heart-throbbing of the Sikhs. He occupies a privileged place as far daily Sikh routine, humility, religious knowledge etc. are concerned. He is perfectly a pious man. He has such a forceful personality that when he stands up and says, "Waheguru Ji ka Khalsa, Waheguru Ji ki Fateh" the lakhs of wavering minds get consoled.
