Bhai Mani Singh was an 18th-century Sikh scholar and martyr. He was a childhood companion of Guru Gobind Singh and took the vows of Sikhism when the Guru inaugurated the Khalsa in March 1699. Soon after that, the Guru sent him to Amritsar to take charge of Harmandir Sahib, which had been without a custodian since 1696. He took control and steered the course of Sikh destiny at a critical stage in Sikh history. The nature of his death in which he was dismembered joint by joint has become a part of the daily Sikh Ardas (prayer).
