The practice of Bon traditions was widespread in Bhutan long before the arrival of Buddhism, and it retains influence in Tshapey village. Previously people practiced animal sacrifice and had faith in nature. With the advent of Buddhism in the country, many elements of Bon dissipated even as Bon rituals continued. Taking on a fusion of Buddhism and aspects of Bon, this became known as Bo-kar, white Bon. This especially allowed Bon rituals to be performed without sacrificing human lives. Den-zha, a local festival in the village of Tshapey, is one of many such Bo-kar practices. This festival is about appeasing Ke-lha the deity of birth, or the local deity known as Nyep Dangnap, who is commonly worshipped as the protector of the Tshapey community. The deity's dark appearance is said to have given her the name Dang-nap, which is further exemplified by the deity's black mask that can be seen in the Lhakhang, temple, today. The Lhakhang, locally known as Haa Goenpa, or monastery. It is believed that the Goenpa was built on the spot where a dove miraculously landed. The dove is considered to be the Nob Denshap, heart emanation, of the Jowo image of Buddha Shakyamuni of Lhasa, Tibet. It is located about seven kilometers from the road. The most important Nangten, or relic, at the Lhakhang is a large statue of the Jowo Shakyamuni. It is said that any wishes or prayers made before the Jowo will come true. In earlier times, the Tshapey community took care of the Lhakhang, but in 1998 it was given to the Zhung Dratshang Central Monastic Body. It was severely damaged by an earthquake and renovated in 1992. Currently, eight people live in and around the Lhakhang - five Tshampa meditators, one Kunyer caretaker, and one Lopen or Lam the spiritual master. On this occasion, the members of the Tshapey community, including those who have moved away to other places, gather at the village Lhakhang to make Nyen-dhar monetary offerings. If they cannot come, they must come and make Shag-pa confession immediately after the festival period.
