Diamond Way Buddhism (Diamond Way Buddhism - Karma Kagyu Lineage) is a lay organization within the Karma Kagyu school of Tibetan Buddhism. The first Diamond Way Buddhist center was founded in 1972 by Hannah Nydahl and Ole Nydahl in Copenhagen under the guidance of Rangjung Rigpe Dorje, 16th Karmapa. Today there are approximately 650 centers worldwide, directed by Ole Nydahl under the guidance of Trinley Thaye Dorje, one of two claimants to the title of the 17th Karmapa (See Karmapa Controversy). Buddhist teachers such as Sherab Gyaltsen Rinpoche and Lama Jigme Rinpoche visit Diamond Way Buddhist centers and large meditation courses.
