Drubwang Drakpa Gyeltshen/ Lopen khizhe: Drubwang Drakpa Gyeltsen was born in the late eighteenth century in a remote area of Trashigang. He was the son of a poor family in the village of Kangpara. As a young man, he was enrolled as a novice in the Tashigang dzong. There he was given the name Drakpa Gyeltsen by Lama Neten. At the time Trashigang Dzong was the only major religious center available to young students to receive education and training in Buddhism. After studying at Trashigang dzong, Drakpa Gyeltsen was appointed to a Palden Lhamo chapel in Trashigang dzong as a caretaker. His regular responsibility was to propitiate the deity each evening and offer her purification prayers and fresh water in offering bowls every morning. He is said to have experienced a vision of the deity in which she commanded him to leave the chapel and travel around as an aesthetic wanderer.

He thus set out, traveling to various locations in eastern Bhutan. He has meditated in forests and on the mountains located at Jomo Dangaling, Tsong Tsongma, Pang zam, and Kangpara Threlphu. It is said that mountain deities occasionally tried to disturb his meditation by appearing in aggressive forms, but he was able to subdue them with his meditative abilities and his all-encompassing compassion. He transformed them, and also, according to legend, wild animals such as tigers and bears, into gentle creatures. The deities reportedly requested him to ask the valley people to become vegetarian in order to show more respect to them. Drakpa Gyeltsen composed propitiating prayers to the deities and their retinues, describing their places of residence.

He built many stupas across Trashigang. One of the largest, in the center of Kanglung village, is Chonga Stupa which was built to resemble the Bodhanath stupa in Nepal. It is said that during the time of its building a group of nuns was having lunch nearby; Drakpa Gyeltsen asked them to share their food with him, but they refused, saying that there was not enough and that he should eat shit instead. So he looked around and found a dried heap of shit nearby, took out his copper spoon, and said a few prayers over it. After a few seconds, the shit streamed up and transformed into ambrosia and Drubwang Drakpa Gyeltsen ate it with enjoyment. Thereafter he was known as Drubthob Khizhe or Lopon Khizhe. The nuns regretted their ignorance and negative actions, and as a sign of confession, they built the Weddum Stupa in Kanglung village.

At the end of his life, Drakpa Gyeltsen visited a village called Martsala Richanglu where people were dying from an outbreak of chicken pox. He helped the villagers cremate the dead and performed the necessary rituals. Unfortunately, he also fell ill, and the villagers carried him to his retreat center at Kangpara. It is said that when they reached Kangpara he asked them if they had arrived, and, as soon as they responded in the affirmative, he passed away. He was cremated at the center, which preserves his relics in a stupa.
