Umang Lai (Meitei: /ū-mang lāi/) are deities in Sanamahism who are the local guardians of a neighborhood or particular area.^[1] Umang Lais are worshipped only two times in a year.^[2] They are the group of sacred groves preserved for the local forest deities (with the same title), worshipped by the Meitei people, the predominant ethnic groups, since ancient times in the Himalayan state of Manipur. The groves and the deities are worshipped and their pleasing ceremony is always celebrated every year through a music and dance festival called Lai Haraoba. There are 365 Umang Lais in the state, out of which 166 are identified in the valley regions of the state.^[3][4][5]
