ANANDPUR DI VAR is a versified account in Punjabi, by one Ram Singh, of a battle fought in 1812 between Sodhi Surjan Singh of Anandpur and Raja Maha Chand of Kahlur. Sodhi Surjan Singh was a lineal descendant of Suraj Mall, a son of Guru Hargobind. His father, Nahar Singh, who was a brave and influential person, had established an independent state by force of arms. Surjan Singh, too, was a man of prowess, and was increasing his area of influence. Maha Chand, the chief of the neighbouring state of Kahlur, was jealous of the growing power of Surjan Singh whom he considered no more than a vassal of his.
AJAT SAGAR, by Surjan Das Ajat, is the religious book of the Ajatpanthi sect of the Udasis. Written in AD 1851, the only known manuscript of the work was available in the Sikh Reference Library, Amritsar, until it perished during the Blue Star action in the holy premises in 1984. The author Surjan Das (father: Bagh Singh, mother: Gulab Devi, a disciple of Sant Tahil Das who was in the Bhagat Bhagvanie sect of the Udasis, established his gaddi at Ajneval, in Gujrariwala district, now in Pakistan. Surjan Das preached the ideal of a casteless (a = without; Jat = caste) society and thus came to be called Ajat and his followers Ajatpanthi.
