Tributes have started coming in for one of the founders of the Samye Ling centre, Choje Akong Rinpoche, who has reportedly been killed in China.
The head of the 900-year-old Karma Kagyu Lineage sent this message:
Akong Tulku has been my friend from the time I was seven. A social activist, he showed great kindness to Tibet by founding schools and hospitals, printing old texts, and helping many people.
"Thus I am shocked to hear that he along with two others has been taken from us so suddenly. I would like to offer my condolences to his family members, everyone at Samye Ling Monastery, the Rokpa Foundation, and all the persons involved in his projects in Tibet as well as to all of the students whose lives he touched.
"I hope that all of his visions and aspirations may continue to be fulfilled.
In 1967 Akong Rinpoche and Chogyam Trungpa Rinpoche founded the first Tibetan Buddhist Centre in the west, the Kaygu Samye Ling centre.
Samye Ling is home to a residential community of over 60 people, made up of both monastic and lay volunteers.
