Our Lineage
Robert Aitken Roshi and his wife Anne founded the Diamond Sangha in 1959 in Hawaii. This lineage now has thirty-seven teachers world-wide including Ross Bolleter Roshi in Perth; Mary Jaksch Roshi, Glenn Wallis Roshi, Arthur Wells Roshi and Sean Weaver Sensei in New Zealand.
Diamond Sangha teachers lead sitting groups and retreats in the USA, Chile, Argentina, Australia, Saudi Arabia, New Zealand, England and Germany.
As the lineage has roots in both the Soto and Rinzai schools of Zen, Diamond Sangha teachers offer both Koan study, and Shikantaza ('just sitting').
Diamond Sangha is a lay lineage, not a monastic lineage, with the ideal of bringing to our practice the joy and pain of everyday life: the great 'monastery without walls'.

Robert Aitken Roshi (June 19, 1917 – August 5, 2010)
In 1959 Robert and Anne Aitken began a meditation group in Honolulu at their residence, which became known as the Koko-an zendo and the community that gathered, as the Diamond Sangha.
In 1974 Aitken was given permission to teach by Koun Yamada, receiving full Dharma transmission from him in 1985.
Robert Aitken was a social activist through much of his adult life, beginning with against nuclear testing during the 1940s. He was among the earlier proponents of deep ecology in religious America, and was outspoken in his beliefs on the equality of men and women. In 1978 Aitken helped found the Buddhist Peace Fellowship, with Anne Aitken and Nelson Foster.
