SHAHID BILAS (BHAI MANI SINGH), by Kavi Seva Singh, is a biography in verse of Bhai Mani Singh, a Rajput warrior of Panvar clan, whom the poet identifies with Bhai Mani Singh, the martyr. Seva Singh, son of Kesar Singh Kaushish, was a bhatt or family bard of one of Bhai Mani Singh`s great grandsons, Sarigat Singh, who had settled at Ladva, in the present Yamunanagar district of Haryana, as ajagirdar under Raja Ajit Singh. According to the poet himself, he commenced writing Shahid Bilas at Ladva, but completed it at Bhadson, in Parganah Thanesar, to which place he migrated, probably in 1846, when Raja Ajit Singh`s estates were confiscated by the British for helping the Lahore armies in the first AngloSikh war.
SUNDAR SHAH (d. 1640), a Muslim saint of Devnagar, probably the present day Deogaori in Azamgarh district of Uttar Pradesh, is remembered in Sikh tradition for his admiration for Bhai Bidhi Chand, a prominent Sikh of the time of Guru Hargobind. Bhai Bidhi Chand was preaching in the eastern parts when Sundar Shah had the chance of meeting him. They became attached to each other and, before Bhai Bidhi Chand left, Sundar Shah made him promise that he would return and spend his last days with him.
