The Boori Boot festival is exclusively performed by the Hill-Miris. The festival usually falls in February. Boori Boot means to get together irrespective of age, sex, caste to hail the spring and successful harvest. The festival also invokes the spirit of Boori Boot to bless them with prosperity and free from diseases of any kind. The Nibu (priest) performs Puja as well as conduct sacrifice. ‘Etting’ is profusely applied on one and all.

Reh is one of the most important festivals of the Idu Mishimis. The Idus believe that they are the sons and daughters of the divine mother ‘Nanyi Inyitaya’. But none can get her blessings and keep alive bond of brotherhood and social feeling strong, unless one performs the puja or celebrate the Reh festival. The festival requires a number of sacrificial buffaloes for offering to the great mother ‘Nanyi Inyitaya’.
