If an Idu Mishmi wishes to hunt animals in the high mountains, he must first seek permission from Golon, the spirit of the high mountains, and promise to abide by all restrictions related to hunting. For the lower mountains and forests, promises must be made to Ashan, the guiding spirit of that region, before hunting or felling trees. If the spirits are offended by a breach of promise, misfortune would befall on the violator, family or neighbours, and it would require an Igu, the Idu shaman who negotiates with the spirits, to seek forgiveness.
