There is an old belief that whosoever dies here, goes to heaven. Keeping in view this belief many people used to pass their last days of lire here. Kabir, in his hymns, has rejected this belief. Some people used to get their heads sawed at Kashi for obtaining salvation. (Sorath M. 5, p. 642). See also Kashi
