In Ambala, the most well-known fair is held at Gopal-Mochan close to Bilaspur in Jagadhari tehsil. There is a holy tank of the same name in the place. The legend is that once Lord Shiva while rescuing Saraswati, who was being pursued by Brahma, struck off the latter's head. A lock of hair was left in Shiva's hand and his body was blackened. For a long time Shiva was unable to cleanse himself. One night, when he was resting at a cow shed he overheard the conversation between a cow and her calf. The calf said he was going to kill his master, a Brahmin, to avoid being castrated. The cow tried to dissuade the calf from the sin, but the calf said, it knew of a tank where it could cleanse itself from the sin of killing a Brahmin. Shiva followed the calf the next day and saw it kill its master. The bodies of the cow and the calf where then blackened until they cleansed themselves by bathing in Gopal Mochan tank. Shiva followed their example and was like wise cleansed. Since then the water of Gopal-Mochan have retained their virtue. It is considered by many to be more efficacious than the waters of the Ganges at Hardwar. The Rin Mochan is another water tank located close to the Gopal-Mochan. A big fair is held in the village in the month of Kartik.
