The tank at Lalitpur is similarly famous for the cure of leprosy. One day, a Râjâ afflicted with the disease was passing by, and his Râni dreamt that he should eat some of the confervæ on the surface. He ate it, and was cured; next night the Râni dreamt that there was a vast treasure concealed there, which when dug up was sufficient to pay the cost of excavation. At Qasur is the tank of the saint Basant Shâh, in which children are bathed to cure them of boils.[26] There are several hot springs in India renowned for their curative powers. These also are believed to be sacred to certain deities. A typical example is that of the hot kund, called _Devki-Unai_, about 30 miles to the south of Surat. Many pilgrims visit the place on the fifteenth day of the bright half of _Chaitra_, when the waters are cool, to offer money, cocoanuts, and red lead to the _Unai Mata_, whose temple stands near the kund. It is said that king Rama built this kund while performing a sacrifice and brought water from the _pâtâl_ (nether regions) by shooting an arrow into the earth. Similarly, the famous hot springs forming one group in a line along the bed of the Tansa river in the village of Vadavli are sacred to the goddess Vajrabai or Vajreshvari, the Lady of the Thunderbolt. According to tradition, this neighbourhood being full of demons the goddess Vajrabai became incarnate in the locality to clear it of the wicked spirits. She routed the whole lot of them, and the hot water of these springs is nothing but the blood of one of the demons slain by her. Her chronicle, or _Mahatmya_, is kept at the village of Gunj, some six miles to the north, and her temple is placed at the top of a flight of steps on a spur of the Sumatra range. A large fair is held here in Chaitra (April). There are other hot springs in the neighbouring villages of Akloli, known as the Rameshwar hot springs, whose waters are gathered out in stone cisterns. In the eighteenth century these springs were much used both by Indians and Europeans as a cure for fevers. In his _Oriental Memoirs_ James Forbes describes the springs as consisting of small cisterns of water with a temperature of 120°. “Except that it wanted a small element of iron the water tasted like that of Bath in England.” In the Ganeshpuri village, about three miles west of Vajrabai, are the two hottest springs of the group. These are resorted to by people troubled with skin diseases.
