The Zen Boat is an outreach activity of the International Buddhist Monastery Zen River Temple.

The teachers living and working on the Zen Boat, Simon Senko de Boer and Helma Jifu Vulink, received dharma transmission in 2014 from Tenkei Roshi, abbot of Zen River. In addition to their work on the Zen Boat, Senko gives meditation classes in Utrecht once a week, while Jifu has become the spiritual leader of Kanzeon Zen Centrum Rotterdam and is living and working there for two to four days a week.

The Zen Boat provides a year-round daily programme of meditation and study classes, combined with individual instruction (daisan) and Buddhist Services every morning, as well as during Summer. Introductory courses are also held several times a year. Once a month, during weekends, city sesshins and days of zazen (zazenkai) take place. There is ample opportunity to stay overnight for a maximum of 8 participants. Online contact is maintained with students who live further away.

The Zen Boat maintains an informal style of practice, inspired by the Three Treasures – the insight of Buddha – the wisdom of Dharma – and the harmony of Sangha. Those Three Treasures are maintained and practised using the Four Training Elements as developed at Zen River Temple.

1) Zazen, a form of sitting meditation that makes it possible to experience our deepest being and to gain clarity about our function in life.

2) Zen Ritual, active forms of group meditation that help us develop a mutual connection with one another.

3) Study, research of Buddhist scriptures and commentaries throughout the ages that support the practice of Zen in both meditation and daily life.

4) Bodhisattva Activity, practice in living a life of wisdom and compassion based on well-tested Buddhist guidelines.

In Zen Boat activities, the aspect of the community (Sangha) is regularly emphasized both within the group of practitioners as well as towards other (local) Buddhist groups. The Zen Boat is open to anyone who wants to get acquainted with Zen practice. Full instruction is given to all newcomers. Questions related to practice can be asked both within the group as well as individually.
