Ati Yoga (Tibetan: Dzogchen) is the most simple, direct, and profound path to reveal the sky-like nature of our own mind which is clear, vast, and unobstructed by the clouds of afflictive emotions.
In this year long meditation-focused immersion, students will be guided through the steps of Ati Yoga practice as taught by Yuthok Yönten Gönpo, the 12th Century father of Tibetan Medicine and explained in the text Mirror of Light: A Commentary on Yuthok's Ati Yoga by Dr. Nida Chenagtsang.
Each week students will be given instruction on the practices, beginning with Guru Yoga, progressing through the Dzogchen special preliminaries (Inner and Outer Rushen) and the actual preliminaries of training body, speech, and mind with Vajra Posture, the Hung Syllable, and mind investigation. The year will finish instructions on Kadak (Primordial Purity) and Trekchöd (Cutting Through Hardness).
Guided practice sessions will be an integral part of this program, providing students with the time to familiarize themselves with and deepen the connection to the practices in a supported group online setting with regular opportunities for questions and discussion. The mixture of live and pre-recorded classes ensure that there is time for both engaged question and response as well as very focused instruction sessions without distractions or interruption.

This year we are implementing the requirement that all participants have either completed the 7-day Yuthok Nyingthik Ngondrö retreat or can commit to the completion of the 7-day Yuthok Nyingthik Ngondrö retreat during the 2026 calendar year. Please understand that this requirement is not a barrier as much as a means to ensure that the participants in the cohort have a certain degree of experience.
