King of Patan, Siddhraj Jaysingh attacked the city of Saurashtra during 1170 AD. He captured the erstwhile King Ra`Khengar and jailed him in his city. When Ra`Khengar passed away, at the behest of Bahad Mantri (minister), King Siddhraj Jaysingh appointed Sajjan Mantri as Governing officer of Saurashtra. Influential, wise and a person with great foresight, Sajjan Mantri won the hearts of the entire Saurashtra region.
He made Junagadh as central place to carry out all operations of Saurashtra. Once, when Sajjan Mantri went on a pilgrimage to Girnar Tirth, he was deeply anguished to see the dilapidated temples and ruined structures over there. At that time, Acharya Bhadreshwarsurishwarji of Raj Gaccha, who fasted every alternate day, was the guru of Sajjan Mantri.
