The author, not many details of whose career are known, was born to Bhai Bakht Singh towards the end of eighteenth century. He was a poet at the court of Maharaja Karam Singh (1797-1845) of Patiala and wrote several books, including Kissa HirRahjha, Bara Maha, GurKirat Prakas, Gopi Chand Vairag Shatak, Sudha Sindhu Ramayana. The Singh Sagarwas written in 1884 Bk/AD 1827 at Patiala. The work, two manuscript copies of which are extant one preserved in the Motibagh Palace at Patiala has since been published (1986) by the Punjabi University.
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.
