Dr Susan Murphy is a lineage-holder in two lay practice lines of Zen that combine Soto (‘just sitting’) and Rinzai (‘koan practice’) – the Diamond Sangha, stemming from Robert Aitken, and Yamada Koun (Sanbo Kyodan) since 1960, and Pacific Zen, stemming from John Tarrant since 1999.
In 2001 she received transmission as a Roshi from both of her primary teachers John Tarrant (Pacific Zen) and Ross Bolleter (Diamond Sangha).
