There are two separate monastery buildings. The first is smaller but more atmospheric and features a statue of Luwang Gyelpo, the king of the naga (snake spirits). Pilgrims test their sin by lifting the heavy stone of Nyenchen Tanglha, the mountain deity who resides in the nearby peak of the same name.
The second, main chapel features a central Guru Rinpoche statue and the trinity of Öpagme, Chenresig and Pema Jigme, known collectively as the Cholong Dusom. Protectors include Nyenchen Tanglha on a horse and the blue-faced Nam-tso, the god of the lake, who rides a water serpent. Both gods are rooted deep in Bön belief. Several other chapels and retreats are honeycombed into the surrounding cliffs.
