The land of five rivers i.e. Punjab is full of historical memorials. This land is proud of the fact that the tree of the Sikh religion which was planted by Sri Guru Gobind Singh was kept evergreen by various saints, the Mahatmas, saint-soldiers, bountiful people and pious men, who were born at different times. In the history of the Sikhs, we find, on one side a long list of those people who were saints, pious men warriors. These people laid down their lives for the greenery of the perpetual tree of Sikh religion. On the other side there are so many saints, scholars and soldiers of the Damdami Taksal, who imparted the education of the Sikh religion to the masses. These scholars are known as Gianis. In the same series Sant Baba Harnam Singh Bedi of the Damdami Taksal was born.
Sant Baba Harnam Singh Bedi had his religious education from the chief of the Damdami Taksal, Giani Sant Bhagwan Singh as well as Bhai Jaswant Singh. He learned from them Sri Guru Granth Sahib alongwith its meanings and explanation, Kabit Sawayas, ballads (Vars) of Bhai Gurdas, Sri Gur Partap Suraj Granth and Vedant.
When Sant Giani Bhagwan Singh left for his heavenly abode he became the ninth chief of the Damdami Taksal, formed by the tenth Guru Sri Guru Gobind Singh. He started a school of divinity at Sri Amritsar Sahib where several students had their education in Sri Guru Granth Sahib, Sri Dasam Granth and many other religious books. He baptized so many people with eternal nectar alongwith certain other Gursikhs, at Sri Akal Takht Sahib.
His students gave the message of Sri Guru Nanak and Sri Guru Granth Sahib in various parts of the country and abroad. Thus, so many people came into the Sikh fold. He used to sit and listen Gurbani and Shabd Kirtan at Sri Akal Takht Sahib. He invented a novel method of explaining the meanings of Sri Guru Granth Sahib which is still adhered to.
Baba Bishan Singh of Murala, Sant Baba Sunder Singh Bhindranwale, Sant Hakim Singh Amritsar, Mahant Harnam Singh of Murala and Sant Bishan Singh Kareet are some of the prominent pupils who got religious education from him.
Sant Harnam Singh Bedi used to reside in Dera Baba Joga Singh, Amritsar. He served as a Granthi of Sri Darbar Sahib. Right from Giani Amir Singh, all the Gianis of Amritsar had their devotional schooling from Baba Harnam Singh Bedi. He continued imparting religious education in his old age as well. He used to adorn himself with black clothes, always. Baba Ji had the privilege of teaching to the pupils of Udasi, Nirmale, Adanshahi (Sewa Panthi), Mazhabi Sikh sects also. He left for his heavenly abode in Dera Baba Joga Singh.
