His father’s name was Bhai Sahib Bhai Surat Singh Ji and his elder brother was Bhai Sahib Bhai Gurdass Singh Ji. He was blessed with three sons- Bhai Deva Singh, Bhai Gurmukh Singh and Bhai Sadhu Singh. His father and his elder brother were also once the Jathedars of Damdami Taksal. His father Bhai Sahib Bhai Surat Singh Ji was the third Jathedar and his elder brother Bhai Sahib Bhai Gurdass Singh Ji was fourth Jathedar of Damdami Taksal. So, he was from a spiritually and a scholarly rich background.
Bhai Sahib studied Sri Guru Granth Sahib Paath, Santhia, Katha and meanings from his father and his elder brother. He studied numerous Sanskrit Granths from Pandit Nihal Singh Ji.
In 1790, the Khalsa Panth asked Bhai Sahib to do Katha of Hukamanama from Sri Guru Granth Sahib Ji in Sri Darbar Sahib, Amritsar. Bhai Sahib obeyed this duty faithfully and honestly in his entire life. Throughout his life he never missed a day. Even once when one of his grandsons died, he did not miss to do daily Katha and Seva of Sri Darbar Sahib.
One day Maharaja Ranjeet Singh sent his two servants to Bhai Sahib to call him to do Katha at Rambagh. At that time, Bhai Sahib was doing Katha at Sri Darbar Sahib. He asked the two servants to sit in Sangat and kept on doing Katha. Later two more servants came for the same. Bhai Sahib made them too in the Sangat and kept on doing Katha. Then Maharaja Ranjeet Singh came. After getti ng about Bhai Sahib’s honesty and sincerity for Guru, he was highly pleased and impressed.
In the battle of Jhang, Maharaja Ranjeet Singh was seriously injured and fell into a deep dig. Bhai Sahib picked him up and carried him over his back and saved his life. Maharaja Ranjeet Singh remembered Bhai Sahib throughout his life for this. As the honour of Head Granthi of Sri Darbar Sahib, he used to wipe the feet of Bhai Sahib with his beard.
The golden coating over Sri Darbar Sahib was done under his supervision. He also inspired Bhai Desa Singh Ji to coat golden over the Nishan Sahib of Gurudwara Baba Atal Rai Ji.
Bhai Sahib was a great scholar. He also did literary work. He wrote Teeka (meaning book of a Scripture) of Tulsi Ramayan (ਤੁਲਸੀ ਰਮਾਇਣ). He also did translation of Tulsi Dass Ram Charitra Maanas (ਤੁਲਸੀ ਦਾਸ ਰਾਮ ਚਰਿਤ੍ਰ ਮਾਨਸ). He also wrote a poem Sri Ram Aswamedh Sehaskrit Bhakha (ਸ੍ਰੀ ਰਾਮ ਅਸਵਮੇਧ ਸਹਸਕ੍ਰਿਤ ਭਾਖਾ).
He was great teacher as well and he taught a lot of students. Out of which the noted ones were:
- Bhai Santokh Singh Ji, writer of Suraj Prakash Granth. He was a renowned scholar of his time and did a great seva for Panth by writing Suraj Prakash Granth. He can be called as ‘Father of Sikh History’. He studied from Bhai Sahib for 15 years.
- Kavi Megh Singh Ji, writer of Bhai Sahib Chandraka in which history and important information about Damdami Taksal and Saints of those days has been accounted.
- Shaizada Nau Nihal Singh, grandson of Maharaja Ranjeet Singh. He was a great personality but was betrayed and murdered by Dogras.
- Sant Daya Singh Ji, also perhaps studied from Bhai Sahib. He became Jathedar of Damdami Taksal after Bhai Sahib.
Bhai Sahib had also done a lot of Naam Kamai. One day a Singh named Gomerkhan Singh came with a dead body of his son and asked Bhai Sahib to make him alive. Bhai Sahib said,” If you want then, I can give my life to him and he will be alive. But who have been invincible in this world. Keep patience. After 10 months, you will be blessed by a new son”. The same thing happened.
Bhai Sahib used to pick up the bird droppings over the Prakarma of Sri Darbar Sahib with his own hands. This has been accounted by Sant Baba Sham Singh Ji Amritsar wale (1803-1926) in Har Bhagat Prem Prakash (ਹਰਿ ਭਗਤ ਪ੍ਰੇਮ ਪ੍ਰਕਾਸ਼) who did Kirtan Seva at Sri Darbar Sahib for about 80 years and saw Bhai Sahib doing this great seva with his own eyes. Bhai Sahib also used to pick up the Kesh from Prakarma and Sanskar them.
Bhai Sahib left for abode of Lord in 1832. After him, his son Bhai Gurmukh Singh became Head Granthi of Sri Darbar Sahib and Sant Daya Singh Ji became the Jathedar of Damdamit Taksal. Bhai Sahib Bhai Sant Singh Ji is truly a role model for today’s Granthis and Paatthis.
