[3] Bhai Dayala was the chief of the sangat (holy congregation) at Patna Sahib and enlisted incharge of all the masands in the east,[4] and when the Guru's son Gobind Rai (Gobind Singh) was born it was him who sent Guru Tegh Bahadur a letter, who was at Dacca, informing him of his son's birth.

[8] Bhai Dayala was one of the followers who accompanied Guru Tegh Bahadur when the latter left Anandpur for Delhi on 11 July 1675, the other two were brothers-Bhai Mati Das, a Dewan and Bhai Sati Das, a Scribe at Guru’s court.

[citation needed] On 11 November 1675 after Bhai Mati Das' execution Bhai Dayala refuted with temperament against the Mughals calling Aurangzeb a tyrant and cursed him for committing atrocities in the name of God and religion and said there would be a demise of the Mughal empire.

[9] Bhai Dayala was tied with an iron chain like a bundle then was made to stand erect into a big cauldron full of water with only his head and shoulders seen.

[10][11] The vessel was then heated to the boiling point as Bhai Dayala began to recite Japji Sahib.
