Sant Giani Bhagvan Singh ji learnt Gurbani and studied religion from Sant Daya Singh ji. Sant ji gave Sant Giani Bhagvan Singh ji the Dastar (turban, meaning leadership) of Damdami Taksal. They would reside in the Majeethiaa Bunga (one of the two towers at Sri Harmandir Sahib). Throughout their life they did an immense amount of Gursikhi parchar.his sateek Giani ji has done a great Seva for the Panth.
Sant Giani Bhagvan Singh ji would spend most of their time reciting Gurbani. They were not affected by maya (worldly illusion) and had a disciplined rehat. While staying at Amritsar they taught and groomed many kathakars and paathis. Three famous Gursikhs Sant Harnam Singh ji, Sant Fateh Singh ji and Sant Ameer Singh ji were students of Giani ji. Sant Ameer Singh ji later became jathedar of the Shaheed Bhai Mani Singh branch of Damdami Taksal. Sant Ameer Singh ji is famous for producing a full sateek of Sri Guru Granth Sahib ji.
Sant Giani Bhagvan Singh ji were a great poet and scholar, and spoke with much devotion. They believed that all our Guru's, including eternal Sri Guru Granth Sahib ji, are the incarnations of Akal Purkh. Giani ji showed immense respect to the Bani of the Bhagats, and produced a sateek of their Bani. It was published in Lahore in 1897, with Bhai Gurmukh Singh Sidhana doing the seva for the printing. Sant ji were asked by the sangat to produce this sateek, as they argued that the Bani has such a deep meaning and the sateek would assist the understanding of many. Giani ji said that this Bani is beyond human description, just as is for all Gurbani. At the start of the sateek they state the following: "I have little sense, with Guru ji's blessings, the understanding I have learnt, that is what I have written. Guru ji is with us and will ferry us across the ocean that is the world." Thus giving us evidence of their nimrata (humbleness).
