A little further south, nestled higher up in the mountains, it is believed that there is a hidden sacred abode of Guru Rimpoche, which will be revealed at a pre-ordained time, for the preservation of the Dharma.
Dungkar was also visited many times by Terton Pemalingpa, the great treasure revealer of Bhutan, who lived in the 15th century.
According to legends, the three older brothers of the twins were approached by the powerful local deity, Aum Wangchen Zangmo, to establish the centre, opposite her abode, on a ridge shaped like a Dungkar (conch). Hence the Nagtshang and its surroundings are known as Dungkar.
In keeping with the purpose of building the Dungkar Nagtshang, as a centre of the Peling tradition, rituals dedicated to Goempo Jatsha is performed even to this day, on the first day of the eleventh lunar month, culminating in a three-day Tshechu (mask dance festival) from the ninth day to the eleventh day.
The dances are all Terchhams (treasure dances), that were once choreographed by Pemalingpa himself.
The family members of the Dungkar Nagtshang, being descendants of a great personage like Pemalingpa, are known as Dungkar Choejey.
Two prominent sons of the Dungkar Choejey were Pila Goempo Wangyel and his older brother, Pala Gyaltshen. Pila, who was born in 1782, went to Gangtoe Goemba to stay with the Gangtoe Trulku Sizhi Namgyel. He led the army of Zhabdrung Jigme Drakpa when the Zhabdrung and Sungtruel Yeshi Gyaltshen were in conflict. After living in western Bhutan for several years, he returned to Dungkar and lived separately at Khetangbi Nagtshang on a hill overlooking the Dungkar Nagtshang.
Pila had five sons, one of which was Jigme Namgyel, born in 1825, who became the dynamic and powerful Trongsa Penlop. Jigme Namgyel successfully led Bhutanese forces against the British in Dewangiri, and laid the foundation for the emergence of the Wangchuck dynasty and the start of a new era of peace and stability in Bhutan after many years of internal strife and conflict.
Khetangbi Nagtshang was rebuilt and expanded during Jigme Namgyel's time by his sister, Ashi Tshewang Dem. It has since been known as the Jigme Namgyel Nagtshang and is looked after, today, by the Lhuentse Rabdey. Religious ceremonies in keeping with the traditions established in the time of Pila Goenpo Wangyal and Trongsa Penlop Jigme Namgyel are still being performed to this day.
