Guru Kian Saakhian was written by Bhatt Sarup Singh Kaushish, of Bhadson, in Parganah Thanesar. As recorded by the author, the manuscript was completed in 1847 Bk/AD 1790 at Bhadson itself. The original manuscript was written in Bhattachchhari, a script used by the Bhatts (or family bards) for recording genealogical details concerning their clients. It was later transliterated into Gurmukhi script by Bhatt Chhajju Singh Kaushish in 1925 Bk/AD 1869.
The work has since been published (1986) in book form. The manuscript contains a total of 112 sakhis connected with the lives of five of the Gurus, Guru Hargobind Sahib to Guru Gobind Singh. Four of these sakhis relate to Guru Hargobind, nine to Guru Har Rai, four to Guru Har Krishan, 16 to Guru Tegh Bahadur and 79 to Guru Gobind Singh.
The first Guru to have Bhatts in attendance was Guru Arjan Dev. They became devout Sikhs. They wrote hymns in praise of Guru Arjan Dev and his predecessors which are preserved in the Sri Guru Granth Sahib. They and their descendants took part in Guru Hargobind Sahib’s battles against the Mughal forces. They put down in their vahis (genealogical records), some of the events connected with the lives of the Gurus. The entries in the Bhatt Vahis are thus historically very important.
