From the founding of Drikung Thil Monastery in 1179 to the present day, the Drikung Kagyu lineage has been led by a succession of spiritual heads ("throne-holders").
The unique doctrines of Drikung Kagyu as taught by its founder, Jigten Sumgön is preserved in "The Single Intention" (Wylie: dgongs gcig)[REF] and "The Essence of Mahāyāna Teachings" (Wylie: theg chen bstan pa'i snying po).
