Summer Zen Sesshin

An Online East-West Retreat
with Nona Strong


July 17-19, 2020


Friday 6:00 pm PT to

Sunday 6:00 pm PT

$225 registration fee


This online Zen sesshin offers an opportunity for you to practice Zen meditation – zazen – in an intensive, structured setting. Owing to the present health crisis, we will use online technology to conduct a virtual gathering in which we can practice Zen “alone together.” Of course, we would all prefer to sit in a proper meditation hall (zendo) and benefit from the physical presence of others, but in today’s circumstances, let us use the tools that technological innovation has so brilliantly provided.


The sesshin prescribes nearly seven hours of silent meditation per day and includes dharma talks (teisho) by and private meetings (dokusan) with Nona Strong, the authorized Zen teacher who will lead the gathering. We will open with an evening of welcome and orientation to the online platform, with a focus on the mechanics of the online dokusan procedure. The next two days of sitting will allow for regular walking meditation periods (kinhin), plus breaks for rest, meals, and time spent outdoors in nature, at your own discretion. We will also experience Zen Buddhist chanting, led by a member of the sesshin staff, which you can follow silently or aloud in your own meditation setting.


This Zen sesshin can become an inspiring spiritual experience for everyone, regardless of your religious affiliation. The days of silence and concentrated meditation will allow you to connect with your own inner being and with what Zen practitioners know as your True Nature.


It is an opportunity you won’t want to miss.

Nona Strong Roshi


"Embracing the Way of Zen, we concentrate our search for answers into a practice of silent meditation, in community when possible, through which the questions (if not all the answers) become increasingly clear. And through our practice, we put all our care for ourselves and others into a boundless medium that can help us carry that search, that practice, and its fruits into the larger world."

In Zen, everybody benefits, including ourselves.
