"According to Hindu legend, Kanya Devi, an avatar of Parvati, was to marry Siva, but as he failed to show up on his wedding day, the rice and other grains meant for the wedding feast remained uncooked and remain unused thereafter. As the legend goes, the uncooked grains turned into stones as time went by. Some believe that the small stones on the shore today, which look like rice, are indeed grains from the wedding that was never solemnised. Kanya Devi is now considered a virgin goddess who blesses pilgrims and tourists who flock the town" (Wikipedia).
