The Dimasa people (or Dima-basa, and also called Dimasa-Kachari ) are a group of people inhabiting Assam and Nagaland states in Northeastern India. Dimasa mythology says that they are the children of Bangla Raja (Earthquake God) and the great divine bird Arikhidima. Bangla Raja’s six sons— Sibrai, Doo Raja, Naikhu Raja, Waa Raja, Guyung Brai Yung, and Hamyadao and Arikhidima are their ancestors, and in Dimasa belief, are ancestral Gods. They are called Madai in Dimasa. Evil spirits born of the seventh egg of Arikhidima are responsible for disease, suffering and natural calamities.
