The Puranas call Mangal the son of Earth. Mangalnath Mandir, on the Shipra in Ujjain, is visited as the place of his birth — quieter than the lanes around Mahakaleshwar, and the ground on which families have offered bhat for generations.
Bhat means cooked rice. People say Mangal Nath when they speak and Mangalnath when they write. Both mean this temple and this puja.
