This site has a long and interesting history...
Several hundred years ago, Docho La Pass was under attack by
demons. One demoness in particular, known as Loro Deum, was a
cannibalistic demoness who frequently disguised herself as a dog.
Along with two other demonesses at nearby passes, she terrorized
travelers, killed and then devoured them. She was eventually
defeated in this location a half millennium ago by The Divine
Madman, Drukpa Kuenley. Her remains are interred in a black chorten
that sits upon a mound close to the nearby temple Chhimi Lhakang,
which was erected in honor of Lam Drukpa Kuenley. Prior to her
death, the Lam bound her to service of the Buddha Dharma, and then
transformed her into a guardian and protector of the Buddha. He
renamed her Chhoekim - and to this day, she is the Guardian Diety
of his temple.
The area near the pass is believed to be inhabited by numerous
spirits and has been occupied by various demons throughout the
ages. According to tales, Loro Deum is not the only demoness buried
near the temple, and was most certainly not the only one defeated
by The Madman.
In December 2003, His Majesty Jiqme Singye Wangchuck, the fourth
king of Bhutan, led the Bhutanese Army to flush out and defeat the
Indian guerillas that were camped in the southern forests of Bhutan
and launching cross-border attacks against India from within
Bhutan.
To commemorate this victorious event and honor His Majesty, Her
Majesty the Queen Ashi Dorji Wangmo Wangchuck initiated the
construction of 108 Druk Wangyal Khangsang Choten, which symbolize
love, selflessness and unity of the Bhutanese people. They encircle
the main monument, which is dedicated to the King.
Seek the tallest of the 108; stand and face towards the SW of
this tallest chorten. Look up the hill towards the thousands of
prayer flags. Notice the two large trees, about 100 meters away.
Your GPS should guide you to the tree on the right. Search within
its roots. You may have to dig a bit. The photo included below has
an arrow that points you to the approximate location of the
