Historical Profile of Dechenphu Geynyen Neykhang by Dungchen Sangay Dorji and Karma Ura
Various literary sources that provide scattered information on Dechenphu (means cave of consummate bliss) show that it is a significant sacred place in general, and the most important place of the protector deity for the followers of Drukpa Kargyu. There is no consolidated account of Dechenphu; pieces of information about it have to be assembled from various sources, in particular from the hagiographies of the successive abbots of Druk Ralung, the hagiographies of Phajo Drugom Zhigpo and his immediate descendants. Lhoi Choejung, the famous history of Bhutan written by Penchen Tenzin Chogyal, the 10th Je Khenpo, contains some information about Geynyen. Because of the widespread belief in Geynyen in Tibet, a Tibetan lama, Jamyangje Drupwang Drodul Dorji wrote a booklet on him. The Late Dudjom Rinpoche was another author who composed drupchog for Geynyen.
