His Holiness Jamyang Lungdok Gyaltsen or Lama Achuk (also referred to as Khenpo Achuck Brioche or Achiu Kamabu or Lama A-chos) (1927-2011) was an incarnation of the great terton Rigdzin Longsal Nyingpo (1625-1682) of Kathok Monastery. He was the head of the Nyingma Sect in China and one the foremost sources of virtue, compassion and wisdom / Dzogchen practices within Tibet. He was born in 1927 in Trom in Eastern Tibet and spent 43 years in retreat with his master Tulku Arik Rinpoche.

At the age of eighteen, his mother offered Lama Achuk to Chomgy Arik Rinpoche as a personal attendant. Chomgy Arik Rinpoche was a famous master who was recognized as an embodiment of Avalokiteshvara. Lama Achuk served Chomgy Arik Rinpoche with Three Joys for forty-three years. Even in the extreme, difficult times of the famine and the great Cultural Revolution, he did not sway from his dedication nor service towards his guru, Chomgy Arik Rinpoche. Enduring great hardship without regard for his own health or life, he served and protected Chomgy Arik Rinpoche. He realised all the secret meanings in Buddha-dharma as a result of the accumulated virtues of his past lives, his sincere practice and his unmoving faith in his guru.

In 1985, Lama Achuk established Yachen Gar (Yachen Orgyen Meditation Monastery) in an isolated valley in Changtai District, Palgyu County of Ganzi (Kandze) in Sichuan Province, China. It is named “ Meditation Monastery” as it concentrates on real practice. Serab Yangdrul Rinpoche said, “Yachen Gar is built on a dragon’s palace. If Lama Achuk was not a genuine emanation of Vajrapani, dragon diseases such as smallpox would have spread.” He also prophesised, “If I have to describe how sublime Yachen Gar is, I would say it is the real Orgyen Copper-Coloured Auspicious Mountain from where many mahasiddhas will graduate.”

In the early stage of its establishment, there were just a dozen disciples studying at Yachen Gar. Lama Achuk gave them teachings such as Ngondro (the Preliminary Practices), six Bardo Inductions, Longsal Inductions and Yeshe Lama. His disciples were required to practice four sessions of meditation on Trekchod and Togyal teachings of the Dzogchen Oral Instruction every day. His holiness then took the disciples to see Chomgy Arik Rinpoche to test the results of their practice. Chomgy Arik Rinpoche full of praised, as they had all recognized their primordial awareness, or Rigpa. From then on His Holiness and Yachen Gar became renowned throughout the world. Disciples started to gather in Yachen Gar from all over Tibet and China in pursuit of these sublime teachings. As the Sangha assembly expanded very quickly, Lama Achuk requested that the monks and nuns live separately along the riverbanks and strictly abiding by the Individual Liberation Precepts. Although famous for its concentration on meditation practice, extensive listening and contemplation is also advocated in Yachen Gar and that meditation practice must be guided with understanding of the Dharma gained from listening and contemplation. Even when in his eighties, Lama Achuk still kept giving teachings. Blessed by the Buddhas and Bodhisattvas in the pure land of Uddiyana, guided by His Holiness Jamyang Lungtok Gyaltsen (Lama Achuk), and also due to the disciples’ own pure roots from previous lives, more and more disciples have revealed signs of attaining ultimate realization and inconceivable achievements in this sacred place where numerous sublime conditions are met. Khenchen Jigme Phuntsog praised many times, “Yachen Gar is a unique place for the transmission of Dzogchen teachings.” Although His Holiness Lama Achuk has been recognized as a perfectly enlightened master and renowned throughout the world, he outlined a small part of his achievements to his disciples in order to improve their faith:

“If the master has not purified his own body, speech and mind, he is not able to truly benefit sentient beings, like a blind person leading a group of blind people. I am the abbot of Yachen Gar. My body, speech and mind have all been purified. The symbol of a purified body is that all the details of bright body mandalas can be clearly seen in my body. The symbol of purified speech is that I can elaborate the true meaning of ‘the inseparability of our own mind and the guru’s mind without any error in my words. The symbol of a purified mind is that I myself have fully realized the union of subject and object (the ultimate awareness) and I can make my disciples who have inherent connection with me attain the same realization.

Khenpo Jigme Phuntsok confirmed that I had obtained the same sublime light body as Padmasambhava and Vimalamitra. At that time only a few people could see my light body. But several years later, more and more people who had connection and faith in me could see my light body. They saw Manjushri or Vimaramitra in blue cassock or Padmasambhava or the Omniscient Longchen Rabjam in my body. Some thought there might be false visions using disciple’s visions as a method of confirmation. But this is not so. True is true, false is false.”

Lama Achuk is the emanation of Rigdzin Longsal Nyingpo, which contains the purest blessing power as if we were receiving it directly from Longsal Nyingpo. It has never been contaminated by those who have broken their vows, so the ultimate blessing of transmission is well preserved.
His Holiness lived in Yachen Gar, an encampment of thousands of monks, nuns, and lay practitioners who wish to follow his profound teachings. Yachen Gar is one of the largest concentrations of Rinpoches and Lamas in the world.
