Legend has it that a young, married woman spirit who in a hurry to fly back to her maternal place destroys literally everything on her path; Bordoisila comes to Assam. The word "Bordoisila" is maybe derived from the Bodo word "Bardoisikla". Bardoisikhla breaks down to "Bar-" meaning wind, "-doi-" means water and "-sikhla" means girl in Bodo language ir other Austric or Tibeto-Burman languages. It represents the Spirit Goddess of Nature, Wind and Rain, and it marks the beginning of the festival month of Bohag/Bwishagu (Spring season). Bardwisikhla is also a dance-form popularly known as Bagurumba.
