Gangging A is a general name for a prayer place of the Donyi-Poloist faith, and especially in the Adi areas. The as a sacred enclosure is a concept popularised by the Donyi-Polo Yelam Kebang since 1996. According to Talom Rukbo, the word is derived from Gangging Siring, the concept of land or holy tree that mediates between the spiritual and the natural worlds, and from which any thing, living or non-living, comes into existence. Gangging congregants have to follow certain rules: for example, male members must sit on the left in rows, and female members on the right, cross-legged. Within the prayer place, there should not be any noise during prayer except the sound of the hymns. Prayers are organized in the prayer place on Sundays, and all of the branches established in each of the villages under the Siang district are centrally regulated by the Donyi-Polo Yelam Kebang. Through the prayer place, codified rituals and practices, and iconographies of the Gods and Goddesses have been introduced.

Priests (nyibu) conduct prayers in the prayer place on Sundays. In Apatani areas, the religion is called "Danyi-Piilo" and prayer place are called meder nello ("purified place"), the first of which was built in 2004, songs and prayers are collected in a prayer book called Lyambope.
