An old farmer, Arak by name, served him, and received instruction from him. Bhai Arak constructed a simple memorial at the mound in honour of the Guru. His descendants continued to manage it until 1883 when Bhai Mall Singh, a mahant of Dhamtan, constructed the square domed Manji Sahib which still stands.
