Kherai
Kherai is the greatest religious festival of Boros. Boros are agriculturalists and their relation with agriculture resonates in their festivals. Kherai festival is performed for the welfare of public and private lives as well as for good harvest. It is intended to appease Bathou or Sibrai along with Mainao or Lakhsmi  (The Goddess of Harvest) and host of other deities. It is of four kinds, namely Darshan kherai celebrated in first week of Kartik, Umrao kherai celebrated during Ashara at the end of Amthisua, Phalo kherai celebrated at full moon day of Magh and Nowaoni Kherai celebrated whenever the family needs to. Darshan kherai is connected to Sali crops and it is meant for Mainao or Lakshmi. Umrao kherai is performed for the well-being of villagers as well as the Ashu crops. Nowaoni kherai is performed to get out of trouble by the family. There are similarities between Ker puja of Tripuris and Kherai puja of Boros.

Kherai dances form the main ritual of Kherai. For a period of three days and nights, Kherai dances are performed to revere the holy Bathou and other deities. Doudini or Deodhani (female exorcist) is the chief dancer and all rituals are performed by her and she is guided by the Douri, the Ojha and a Githal. Also two drum beaters, two flautists and two Jotha players are necessary to perform Kherai.
During Kherai, first, the Ojha enchants a spell on the Doudini and it is called Alongikhangnai, second, she falls in trance, and in the third stage, she is believed to be converted into a spiritual being.
