Rooted in Lineage. Guided by Realization.
The Rimé, or non-sectarian, approach to Vajrayana practice recognizes that authentic realization does not belong to any single lineage. It lives in the unbroken transmission passed from master to student across generations. At Yangti Yoga, our teachers and advisors represent a rare breadth of living lineages, each holding a distinct thread of the Vajrayana dharma. While our primary focus is holding and and offering instruction on the various dark retreat instructions that were developed by Dungtsö Repa and various Yangti Nakpo lineage holders, Yangti-based dark retreat instructions intersect with a number of wider Vajrayana lineages. In this respect, we adhere to the idea: Same vision, different missions. In this sense, we all share the vision, deep commitment towards high integrity practice of dark retreat, while also having intersecting, and at times, unique activities in relationship to dark retreat.
We are honored to hold this work in relationship with the teachers below, whose guidance shapes every aspect of how we practice, teach, and build.

H.E. CHUNG TULKU RINPOCHE
Yangti Nakpo Lineage Holder & Advisor
His Eminence Chung Tulku Rinpoche is a recognized tulku and a living holder of the Yangti Nakpo, one of the rarest and most profound cycles of dark retreat practice within the Vajrayana. Rooted in the Dzogchen tradition of Bhutan, Chung Rinpoche carries an unbroken transmission of Yangti practice that is among the most direct and complete available today.
Chung Rinpoche trained under some of the most eminent masters of the Nyingma and Kagyu traditions and has devoted his life to preserving and transmitting the Yangti Nakpo lineage in its full integrity. He is based in the Paro valley of Bhutan where he continues to teach, practice, and hold this living tradition. When he was six years old he e recognized himself as the body reincarnation of the previous Chung Rinpoche, a well-known dark retreat yogin who was a student of Lochen Shukseb Jetsun Chönyi Zangmo - a recognition that was confirmed by the previous Dilgo Khyentse Rinpoche. Later, in 1996 at the Nyingma Monlam Chenmo in Bodh Gaya, His Holiness Penor Rinpoche recognized and enthroned Chung Tulku as the mind reincarnation of Trulshik Dongak Lingpa, the important terton who was the Yangti Nakpo teacher of Lochen Shukseb Jetsun Chönyi and an important force in revitalizing the Yangti Nakpo lineage.
Yangti Yoga’s relationship with H.E. Chung Rinpoche is one of the most treasured aspects of our work. United by a shared commitment to uplifting and preserving the rare Yangti Nakpo lineage, our ongoing partnership takes three forms:
Each year, Lama Justin and H.E. Chung Rinpoche lead a Dzogchen pilgrimage through Bhutan, tracing the footsteps of Padmasambhava, Yeshe Tsogyal, and Longchenpa through sacred sites, pristine forests, and places of living practice. Pilgrims receive transmissions, engage in retreat, and connect directly with the ground of these teachings.
Chung Rinpoche visits Yangti Yoga Retreat Center to offer teachings and transmissions directly to our community bringing the living lineage of the Yangti Nakpo to our land in the Berkshires.
Additionally we are honored to support and be affiliated with Chung Rinpoche’s nunnery in the Paro valley - Tshogyel Lungtok Tengayling Nunnery - a community of dedicated female practitioners whose continued work is itself an act of preservation of this rare and precious tradition.
