The legend or Chait Mangalvar vrat katha is associated with a woman belonging to scavenger community known as Chaiti. She used to offer wine, meat, and eggs to Mangala. She once saw inauspicious face of the Raja of that kingdom and expressed her fear in disgust.
The Raja felt ashamed and crushed all her sons under a chariot. But they restored to life by the divine grace of Goddess Mangala. Since then the Raja and the queen worshipped Goddess Mangala and blessed with sons.
