NIHAL SINGH DAMDAMIAN, 19th century Nirmala saint, a native of Mimsa village of the former princely state of Patiala, received initiation and religious education at the hands of Mahant Dunna Singh, of Uchcha Buriga, a Nirmala sanctuary at Damdama Sahib, Talvandi Sabo, in present day Bathinda district, and became head of the Buriga after the latter`s death. He was respected for his humility and unassuming nature and for the zeal with which he served in the Guru ka Larigar and the loving care with which he looked after the cattle in the shed. In 1860, he with a band of youthful devotees, went to Dera Baba Ram Rai in Dehra Dun and, felling one of the tallest trees in the pine forest of its extensive estate, brought it to Talvandi Sabo carrying it on their heads all the way to Patiala and thence on bullock carts arranged by Maharaja Narinder Singh of Patiala to Damdama Sahib where it was put up as the religious flagmast. Reaching Damdama Sahib, Nihal Singh humbly stood at the entrance where the sangat had deposited their shoes and would not enter the Takht Sahib until he had obtained pardon by paying penalty for having violated the Sikh code of conduct forbidding any dealings with the followers of Baba Ram Rai.

CHALI MUKTE, lit. forty (chalf) liberated ones (mukte), is how a band of 40 brave Sikhs who laid down their lives fighting near the dhab or lake of Khidrana, also called Isharsar, on 29 December 1705 against a Mughal force in chase of Guru Gobind Singh are remembered in Sikh history and daily in the Sikh ardas or supplicatory prayer offered individually or at gatherings at the end of all religious services. Guru Gobind Singh, who had watched the battle from a nearby mound praised the martyrs` valour and blessed them as Chali Mukte, the Forty Immortals. After them Khidrana became Muktsar the Pool of Liberation.
