Diamantweg
Upon returning to Europe in 1972, the 16th Karmapa asked Hannah and Ole Nydahl to begin teaching Buddhism and organize meditation centers, first in their native Denmark, then in Germany and other countries. The centers belong to the Karma Kagyu lineage and operate under Ole Nydahl's practical guidance. In the early 90s, Diamond Way Buddhism was founded as a way to protect established centers during the Karmapa controversy.
