He left Amritsar and went to Kurukshetra where he became a disciple of Pandit Man Singh, a noted Nirmala scholar of the time. Later, he moved to Haridvar and settled at Kankhal where he established his dera or monastery on an extensive piece of land gifted by the Muslim chief of Jualapur. He also built a shrine dedicated to Guru Amar Das (1479-1574) who had visited Haridvar several times. The dera of Bhai Dargaha Singh, patronized by Raja Sahib Singh and Maharaja Karam Singh of Patiala, developed into a prominent centre of the Nirmala sect. Bhai Dargaha Singh died there in 1823.
