Abbot | Head Teacher

Tenkei Roshi

Anton Tenkei Coppens (Netherlands, 1949), the abbot of Zen River, has a background in art and art history and started Zen practice in England in 1976. He continued with Maezumi Roshi and Genpo Roshi in the US and lived and trained there for many years.

After Dharma transmission in 1996, he assisted Genpo Roshi in teaching for four more years and then went to Japan with his wife Myoho to study with Maezumi Roshi’s brother, Junyu Kuroda Roshi. Later, in Zuijoji, he completed the training necessary for accreditation by the Japanese Soto School.

Finally, he and Myoho returned to The Netherlands and established Zen River. Tenkei received Inka in 2006 (the final seal of approval) from Genpo Roshi.

In 2021 he published Timeless Calling, Timely Response, a guide for Zen Buddhist Practice. In 2024, he republished Teaching of the Great Mountain, a series of Dharma talks by Maezumi Roshi that he edited. In 2025, he published Finding Zen River, a collection of letters and news-bits written to sangha-members around the time they set up Zen River Temple.

To date, Tenkei has appointed eleven Dharma successors.

Tammy Myoho Gabrysch was born in Edinburgh (1961). She studied Fine Art in Manchester and worked as a freelance artist and a musician until she met Genpo Roshi in 1988. She then lived in the Kanzeon Zen Centre in Maine and Utah for twelve years, where she discovered her vocation as Tenzo (head cook).

In 2000, together with Tenkei, she studied for six months in Japan with Junyu Kuroda Roshi and later did her official Soto temple training in Toshoji. She received Dharma transmission from Genpo Roshi in 2008, and Inka in 2018.

After setting up Zen River Temple with Tenkei, she shared her decades of cooking experience in her Zen River Cookbook series. In 2025, she published Finding Zen River, a collection of letters written to friends and sangha members from herself and Tenkei Roshi during the time they were searching for a building to start Zen River.

She also released her musical renditions of Buddhist chants as an album called ShoSaiMyo under the artist Myōra.
