The Zen tradition began in early Medieval China and from there branched throughout East Asia. As it moved from country to country the style changed, adapting to local conditions, although both the lineage itself and the deeper goal of awakening continued. Today many of these Zen streams have flowed to North America. Lineages and schools from China, Korea, Japan, and Viet Nam are all represented among AZTA membership. Additional information about the various Zen lineages will be provided here in the near future.
