Explanation:

Sarna sthals are sacred groves in the religious traditions of the Chota Nagpur Plateau region in the states of Jharkhand, Bihar, Assam and Chhattisgarh. Followers of these rituals primarily belong to the Baiga, Oraon, Ho, Kurukh, Munda and Santal. According to local belief, a Gram deoti or village deity resides in the sarna, where sacrifice is offered twice a year. In recent years many tribal and Kudumi Mahato organization have demanded a religious code for Sarna, separate from Hinduism, as they believe that they are nature worshippers.
