Welcome to Green Bay Zen Center

The Green Bay Zen Center offers both the beginning and experienced student an opportunity for Zen practice, Buddhist study and fellowship with others interested in the practice of Dhyana meditation. GBZC provides zazen and discussion twice each week and we hold week-end retreats in Green Bay, WI each Spring and Fall. The Sangha also supports a week-long Sesshin (practice period) each November to commemorate Buddha’s Enlightenment.

All are welcome to join and sit, to explore the quiet of zazen and the fellowship of community. There is no cost to attend our twice-weekly gatherings.

All teachings and readings during Green Bay Zen Center services are contained and read from the Hollow Bones Sutra Book.

Our History

GBZC History

The Green Bay Zen Center originated in 1994 as The Green Tara Sangha sharing space with the Bay Area Yoga Center until 2018. The Sangha was sanctioned by Roshi Jun Po Dennis Kelly, founder and Abbot of The Hollow Bones Order. Jun Po is Dharma heir to Eido Shimano Roshi, founder of the Zen Studies Center in New York. The Sangha shared space with the Bay Area Yoga Center until 2018, coinciding with the formal name change to ‘The Green Bay Zen Center’.

Jun Po had been coming to Green Bay for several years to co-lead week-end Zen/Yoga retreats.

Classically trained for many years in Rinzai Zen, Junpo determined there was enough commitment in the Geen Bay area to support a permanent Sangha (Zen Community) and offered to support the group for a minimum of ten years. Participants came from all over Northeast Wisconsin and the week-end retreats continued along with twice weekly sits in Green Bay.

Beginning with meditation at the Bay Area Yoga Center (sitting on rolled up blankets and sharing space), the Sangha grew and became a single presence for experienced and exploring practitioners.

Several years later, members left Green Tara to establish the Zen River Sangha in Appleton. Additional Sanghas were established in several Wisconsin communities, loosely under the Friends of Zen umbrella. Similarly, through practice with Jun Po, regular retreats occurred in other part of the U.S.

John Nemick took Jukai (a ritualized form of declaring commitment to practice and to support of the Sangha) along with several other Green Tara members.

As the various sites took root, Jun Po ordained Priests into the Hollow Bones Order and more students followed in taking Jukai. In 2014, Vimala Muni, John Nemick was given Inka status and became Roshi (Senior Teacher).


Upcoming Retreats

Hollow Bones

Hollow Bones Order

Hollow Bones Zen began in 1999 in response to a request from the Mankind Project to create a complimentary training and practice structure that embodies Zen Buddhist teachings. The early retreats were made available to men who had participated in the Mankind Project and in 2002 expanded to include women trough co-ed retreats and workshops. The Hollow Bones Zen Retreat is a modern American Zen meditation retreat, Its root and form are adopted from the Japanese Samurai Zen Tradition. The language used is English, and all of the practices are articulated and clearly understood.

About Rinzai Zen School

Hollow Bones is an American Rinzai Zen School. This school provides a clear, open channel for awakening our body, mind, and spirit. This school is specifically tailored for contemporary Western culture.

It is Zen stripped bare and separated from its Japanese cultural identity. It is Zen investigated, understood, and practiced deeply. It is a pragmatic, non-sectarian spiritual discipline and way of life that awakens us and transforms our lives.

From this perspective to consider Zen a religion is to miss the point.

Mondo Zen

Mondo Zen transcends the hierarchical/authoritarian, gender-biased and constraining monastic aspects of traditional Zen in favor of practical, experiential “in the world” engagement. Relying only on direct personal experience – as taught by the Buddha himself – it does not allow mythic constructs to complicate its philosophical orientation. This includes ideas such as reincarnation, soul as personality, bardo realms, past lives, a creator deity, or other faith-based beliefs. It is important that in our practice of Mondo Zen™ we consciously choose to set aside all such ideas at least until we have experienced, tested and evaluated for ourselves a simpler and stronger way of knowing.

Mondo Zen™ Is Based On Japanese And Chinese Zen, Updated For The 21st Century.

“What is most essential is the practice of Dhyana, meditative mindfulness, which enables us to experience the Absolute Purity of our deepest nature and to hold that transpersonal truth in the complexity of our personal lives.” ~Jun Po
