The central Tsuglhakhang is an elegant brown stone structure on the west side of the courtyard. As you walk clockwise, the first chapel you'll see is the Zheye Lhakhang, with statues of Guru Rinpoche and Terdak Lingpa (with a white beard and excellent hat). The bare main hall itself has another statue of Terdak Lingpa, along with Dorje Chang and a row of seven Kadam-style chörtens – the monastery originally belonged to the Kadampa school.
The inner chapel has a large Sakyamuni statue. Only the statue’s head is original; the body was ripped apart by Chinese troops for its relics.
Upstairs, the Tresor Lhakhang houses several treasures, including a stone hoofprint, a mirror that takes away disease and a famed old thangka with the gold footprints and handprints of Terdak Lingpa, which was given to the fifth Dalai Lama.
The top floor holds the Lama Lhakhang, with some fine ancient murals of the Nyingma lineages, plus a central statue of Kuntu Zangpo (Samantabhadri). The Dalai Lama’s quarters remain empty.
