The following is an excerpt from Her Majesty the Royal Grandmother of Bhutan's to Brilliant Moon: The Autobiography of Dilgo Khyentse.
Queen Mother [now Her Majesty the Royal Grandmother] Kesang Chödrön Wangchuk is the wife of the previous king of Bhutan and the mother of the present [now retired Fourth] King Jigmey Senge Wangchuk. She was a devoted disciple of Dilgo Khyentse, and with his guidance, she and her mother, Mayum Choying Wangmo, sponsored the annual sacred drupchens performed by Dilgo Khyentse in the Paro Kyechu temple, the Punakha Dzong Chakrasamvara temple, and the Bumthang Kurje temple. She also sponsored the building of many beautiful temples and holy images in Bhutan.
For a bit more insight into this extraordinary person, see Dzongsar Khyentse Rinpoche's recollection and tribute to her.
