The officials saw that the grinder of Baha Ji was moving on its own. They inform ed Itabal about it who called Baba Ji to his court and talked to Baha Ji. He was pleased and impressed by Baba Ji and ordered his immediate release. Baba Ji ordered the release of other prisoners and 11111 thousands of prisoners were released due to Baba Ji. A Gurdwara was built at the site where Guru Ji turned grinding wheel . A fair is held on Visakhi.
