Namo Buddhaya,
Om Mani Padme HumKARMA TRIYANA DHARMACHAKRA (KTD) is a Tibetan Buddhist monastery beautifully situated in the heart of the Catskill Mountains above Woodstock, New York. It is the North American monastic seat of His Holiness the Gyalwa Karmapa Ogyen Trinley Dorje, the spiritual head of the Karma Kagyu Lineage of Tibetan Buddhism.
KTD is a retreat center where students study and practice Tibetan Buddhism as taught by its distinguished resident lamas, Bardor Tulku Rinpoche, Khenpo Karthar Rinpoche, and Khenpo Ugyen Tenzin as well as many visiting Kagyu teachers.
The abbot of Karma Triyana Dharmachakra is Khenpo Karthar Rinpoche. Bardor Tulku Rinpoche is the third in his lineage and also lives at Karma Triyana Dharmachakra. Tenzin Chonyi is the president of Karma Triyana Dharmachakra. Together they hold the primary responsibility for fulfilling His Holiness' wishes with regard to KTD and its manifold activities.
In addition, KTD has an international network of local practice centers known as Karma Thegsum Chölings (KTCs), which are under its direct spiritual guidance.
