Neither medicine nor prayer to the patron saint of his seel, Sakhi Sarwar, proved of any avail. He met a Sikh who counselled him to pray to God Almighty and to Guru Nanak. Langah soon recovered and was converted a Sikh. He lovingly contributed the labour of Ins hands as well as money for the excavation of the sacred pool and the construction of the Harimandar at Amritsar. His devotion and earnestness wcre applauded by Guru Arjan, who appointed him a masand (officiant) in his own area.
He was one of the privileged Sikhs who were included in the marriage party of Guru Hargobind in 1604. Langah, again, was one of the five Sikhs chosen to accompany Guru Arjan on his last journey to Lahore. He witnessed the torturous scenes leading to the Guru`s martyrdom and helped to cremate his earthly remains. He continued to enjoy the confidence of the next Guru, Guru Hargobind . Known for his fighting skills as well as for his religious faith and piety, Bhai Langah was appointed one of the commanders of Guru Hargobind`s newly trained force.
Later, when the Guru visited Lahore and had a small shrine constructed on the spot where Guru Arjan`s body had been cremated, Bhai Langah was appointed to look after it. He served in this capacity for many a long year. Bhai Langah died at Dhilvari, on the bank of the River Beas. Among Bhai Langah`s descendants was the Sikh general, Baghcl Singh of KarorsinghTa misi, who triumphantly entered Delhi in 1770 and had several Sikh shrines erected to mark the historical sites in the capital. Mai Bhago, who fought with the Majha contingent in the battle of Khidrana (present day Muktsar), was the granddaughter of Bha! Langah`s younger brother, Piro Shah.
