Jatsön Nyingpo (འཇའ་ཚོན་སྙིང་པོ་, 1585–1656) is a famous terton. His termas are collected in six volumes—the Jatsön Pö Druk (‘ja’ tshon pod drug)
“Jatson Nyingpo spent seventeen years in retreat, sealing the door of his hermitage with clay. According to his hagiography, while in retreat or soon afterwards, at the age of thirty-six, in 1620, he revealed a treasure inventory said to be written in the hand of Yeshe Tsogyel (mtsho rgyal gyi phyag bris ma), and went on to reveal numerous treasure texts, including his best known cycle, the Embodiment of the Precious Ones (dkon mchog spyi ‘dus), a Guru Rinpoche sadhana which has inspired numerous commentaries and was a personal practice of Jamgon Kongtrul (‘jam mgon kong sprul, 1813-1899)” (https://treasuryoflives.org/biographies/view/Jatson-Nyingpo/11572)
Khentrul Ngawang Lhundrup edited and typed the six volumes and offers them here for all followers of the Dharma who wish to study them.
