Baba Amar Singh Ji started the "Parchar" - preaching of the Sikh religion, singing of the holy hymns, baptising devotees and starting educational institutions in various parts of the world.

In 1972, upon the request of the devotees of Dunstall Road, in U. K., a house was purchased to start a Gurdwara. At that time nobody could ever dream of building a new Gurdwara costing 1 million pounds sterling on that site. The land next to this place was also purchased at quite a hefty sum of money. Similarly the foundation stone of Nanaksar Thath Isher Darbar, Wolverhampton, U.K. was laid on that very site where Sant Baba Isher Singh Ji, Rara Sahib Wale held their last gathering of their life. Earlier a hall in Wolverhampton was booked for a "kirtan" session for a continuous duration of 14 days by Sant Baba Isher Singh Ji. Sant Ji used it for holding the "Diwan" for 13 days but on the last day Sant Ji left for this world for their heavenly abode.

Later Baba Amar Singh Ji also booked the same hall for "kirtan" gathering and finally purchased that place to build a Gurdwara on that very site. Now there is a small library and a separate hall for organising functions in the Gurdwara. "Gurmat", religious classes, for the correct reading (pronunciation) and understanding of the Guru Granth Sahib are held in the Gurdwara. Various other religious activities are also arranged and held in the Gurdwara for the benefit of the local children.
