Stonewater Zen Teachers

Keizan Scott Roshi – Founder and Teacher

Rev Dr David Keizan Shoji Scott is the founder and leader of the StoneWater Zen Sangha. He is an ordained Buddhist priest and lineage holder in the Soto Zen school, having received Shiho (Dharma transmission) from Tenshin Fletcher Roshi in October 2009. Keizan is also a widely published writer on Japan, Zen Buddhism, comparative religion and cookery.

After gaining a doctorate at Manchester University, he left academic life to travel and write. He went to Okinawa in 1974 where he studied karate with Master Kanei Uechi at the dojo in Futenma. On his return to Liverpool, he started his own dojo and founded the Uechi-Ryu Karate Association (Great Britain).

Roshi has been a Zen practitioner with White Plum Asanga since 1982, intially under the guidance of Genpo Merzel Roshi of the Kanzeon Sangha.
In 2002 he was given the rank of Hoshi (“Dharma holder”) by Genpo Roshi.
In 2006, he was ordained as a monk by Genpo Roshi at the Kanzeon Zen Centre in Salt Lake City, Utah, and he was authorised by Genpo as a Big Mind facilitator.

In November 2008, Keizan formally became a student of Tenshin Roshi who he had by then known for fifteen years, and was ordained as a priest by Roshi at a Denkai ceremony at Yokoji Zen Mountain Center, California. This qualified him to give Jukai (precepts) and Shukke Tokudo (ordination).

In October 2009, Tenshin Roshi recognised Keizan as a lineage holder in a Dharma transmission ceremony in Liverpool. He was given the name “Keizan Shoji”.

In 2014 Keizan was nominated and elected as a full board member of White Plum Asanga and is acting representative for Europe including the UK.

In April 2019 Keizan was given Inka by Tenshin Roshi.  He is now addressed as Keizan Roshi.

Kogen Heale Sensei – Teacher

Simon Kogen Heale grew up as part of a Quaker community which provided him with his first experiences of shared silence. In his early twenties he travelled overland to Asia encountering Buddhism for the first time in China and Tibet. He continued to combine travel with working with homeless communities, University life and Buddhist practice throughout his twenties. During a sesshin in the UK in 1999 he met Genpo Roshi and shortly after moved to SLC, Utah, where he lived mostly for 6 years. He next spent over a year at Yokoji training with Tenshin Roshi and there he completed Hossen Shiki.
Simon moved back to the UK in his early forties. From 2010 until present he has continued his practice with Keizan Roshi who he met along with Tenshin Roshi, at the same early sesshin in 1999.
Arriving back in the UK he trained at the Karuna Institute as a Core Process Psychotherapist and as well working as the Assistant Director of the Centre for Better Health, a Mental Health Charity in Hackney, East London. Simon now lives and works as a psychotherapist in Sheffield, England with his partner and her daughter . They all enjoy everything the Peak District National park, which is on their doorstep, has to offer including cold water swimming and foraging. Kogen Sensei received Shiho from Keizan Roshi in March 2022.

Jeremy Ryokan Sensei – Teacher


The inner life and the mystery of life spoke to Jeremy from his early years. Seeking clarity he studied Theology at Bristol University and there encountered Zen. A mentor taught him to meditate in the Burmese Forest Tradition. Imbued with Christian spirituality, drawn by the East, pulled into the peace movement and social action,and years of work with refugees and survivors of political violence, his journey took him deeply into contemplative Catholicism.

Occasional meditation practice was utterly transformed when he met Fr Ama Samy, a Jesuit Priest and Roshi, dharma heir of Yamada Koun in India in 1998.  A deepening appreciation of Zen co-existed alongside Christianity and transformed his appreciation of the mystery of the incarnation, which resonated with a timeless non-duality.

Back in England he met Fr Patrick Eastman, freshly returned from the USA, and joined the newly formed Wild Goose Zen Sangha, part of the White Plum Asanga, which led to transmission as Sensei in 2016. In the following year God just disappeared, the notion of living in a created world gave way to the ceaselessly unfolding mystery of the Tathagata, and at the centre of it the liberating beat of the Heart Sūtra: “Form is no other than emptiness.”

This hasn’t been a simple process, as he has delved into the mythos of Buddhism to lend scope to his experience. Friendship with Dave Keizan Scott led to a wonderful invitation to join Stonewater Zen Sangha and to follow the path of ordination, which has filled him with profound joy.

Manu is an author, existential psychotherapist/supervisor with a background in philosophy and rock music. He first encountered the Dharma in 1978 in the person of Lama Yeshe during a Lam Rim retreat in a Tibetan monastery in Tuscany. He was a disciple of Osho from 1980 to 1992, living mainly in India during that decade.

Between 2006 and 2016 he studied Korean Zen with Stephen Batchelor.  Between 2016 and 2021 he facilitated therapy groups for men. He received Hōshi from Keizan Roshi in May 2024 and was given a new Dharma name, Myōshin, ‘luminous heart’. He feels that for him one of the difficult gifts of zen practice is the tangible reminder that when the heart breaks it becomes  open, at times joyous. Manu has been a visiting tutor at several colleges/universities in the US, South America, eastern Europe and currently teaches existential coaching and existentialism at Cambridge University and Goldsmiths College London. He authored/edited many books on the cusp of philosophy/’spirituality’/psychotherapy, including Buddha is Dead (2006); Spectre of the Stranger (2006); After Mindfulness (2014); Zen and Therapy: Heretical Perspectives (2017); Nietzsche and Psychotherapy (2019), and Subversion and Desire: Pathways to Transindividuation (2023).
