In 1685 he invited Guru Gobind Singhto live in his realm. The reason for him doing so has been attributing either to him being highly reverent of the Guru, whose life was endangered in Anandpur due to hostile rajas seeking to eliminate him or as a realpolitik move to ally himself to the Guru to prevent any possible attacks on his state by rival kingdoms. Mat Prakash did not joinBhim Chand (Kahlur) and the other local rajas in their wars against the Sikhs.
