The 100th anniversary of the Agricultural Course marks a significant threshold for the biodynamic movement. How did the agricultural course in 1924 come about and which significant events of the present show us a viable way into the future? This question will be explored on the basis of one’s own path…
Marcel Waldhausen is a biodynamic farmer, agricultural machinery mechanic and engineer. He is currently working at Demeter in the West, Germany, in the care of the members. For years, he has devoted himself to deepening the agricultural course and to the question of a contemporary approach and the practical application of Rudolf Steiner’s ideas. As a lecturer, he gives lectures and workshops worldwide.The lecture is free, but a $15 suggested donation will help to support this program and provide for a speaker honorarium.

Weekly online groups exploring spiritual science an its relationship to modern technology
Can a real community form online?
A conference can introduce a question. A study group has time to live with it — to read carefully, listen to one another, and ask what Rudolf Steiner’s work may reveal about the significance of our technological age.
This autumn, MysTech is offering twelve-week online groups drawn from Steiner’s lectures and books. These timely courses consider what humanity faces, the meaning of the human being, the proper course of human evolution, and the challenge of machines shaped by Ahrimanic intelligence.
If you are relatively new to Anthroposophy, the First Course is the natural place to begin. Experienced students are welcome to enter another course or return to earlier material; many participants find that the work deepens through repetition.
| The Autumn term begins the week of September 6, 2026. Participation is free, and each confirmed group meets online once a week with a host. |
Refined Breathing will be added when its session timezones are confirmed. Courses without a confirmed host can be studied individually without a host but will remain unavailable for registration.

Honeybees stand at a threshold. Their health and future are in question worldwide, calling us to reimagine our relationship with these remarkable beings.
Join us at Filigreen Farm and Forest, among our living “bee nests” sited within trees and across the land, to explore what wild, free-living honeybee colonies reveal about resilience, self-healing, and belonging within a thriving landscape.
This event is guided by colleagues from Apis Arborea — a California nonprofit devoted to wild honeybee conservation through a holistic ecological framework — grounded in long-term field research, biomimetic nesting structures, and deep attentiveness to the bees’ own nature.
Location: Filigreen Farm 11600 Anderson Valley Way, Boonville, CA
Date: Saturday, August 15th, 2026
Time: 9 AM – 1 PM
Cost: $125, includes farm-fresh lunch
Fifty percent of proceeds will go to support the work of Apis Arborea.
Outdoor footwear such as boots or sneakers is recommended.

Annual MysTech Conference 2026: Becoming Aware of the Etheric
For our landmark 10th conference, we turn our attention to the etheric realm — the domain of living, formative forces that exists between the physical plane and higher spiritual planes. As technology increasingly shapes the conditions of modern life, understanding these life forces becomes essential for counterbalancing our slide via technology into sub-nature.
Our speakers will explore practices, such as eurythmy, for opening doors to etheric perception. Using Goethean science, we seek to discover the living qualities within substances and elements. Can each of us strengthen our etheric vitality to fully participate in our age of screens and social media? Can we find Christ in the etheric to be our brother as we necessarily tread through Ahriman’s sphere?
“We can only become sure of ourselves as human beings if we walk the road created by the whole of technology, but do not let our lives be governed by the products of technology, and grow able to behold the Christ power that can become part of us and overcome all those products of technology.”
— Rudolf Steiner
“Through meditation the etheric body gets the tendency to become separated from the physical body.”
— Rudolf Steiner
All sessions are online via Zoom. Times shown are Eastern Daylight Time.

A Festival organized by the Eurythmy Association of North America (EANA)
The Calendar of the Soul with its 52 verses is the inspiration behind this event. Rudolf Steiner composed the calendar to tune the soul as a companion through the year. Later on he also created eurythmy forms for each verse in variously sized groups. This festival will bring all 52 verses to performance in eurythmy in English, as a U.S. premier. EANA has gathered groups nationwide (including Canada, Mexico and Taiwan) to prepare the verses for performance at the festival.
We welcome the general public interested in exploring this remarkable progression through lectures, and artistic workshops in eurythmy, speech, painting and plant dying. Professional level courses in eurythmy are taught by distinguished teachers in the field from the U.S., Holland, and Germany.
The festival features Mary Stewart Adams, Mac Mead and Daniel Hafner as keynote speakers in the morning and offers evening performances of Poetry, Music and Eurythmy (featuring segments of the whole calendar). The event’s culmination is on Sunday morning with the US premier of all 52 verses performed in sequence in eurythmy. We will witness the unfolding of the breathing of the human soul and cosmos in the realm of the etheric. We look forward to welcoming you on the grounds of the Threefold Educational Foundation.

Online Symposium
July 10, 2026
The Symposium will include a keynote address by Ben Klocek, discussion groups, and a moderated panel discussion. Ben’s talk will invite us to consider what it means to educate the human being in a time of rapid change. As technology amplifies our capacity to act, feel, and think, how do we cultivate balance, depth, and discernment? Along with us, Ben will explore how the rhythm of the school day, movement, art, and thoughtful engagement, can support the development of grounded, integrated, and wise human beings in an age of acceleration.
Alliance Members: $60 | Non-Members: $75
The symposium is included with Week I and Week II registration.

Through our speech, we impact the world and those around us. Our inner life flows outwards over our vocal cords on our breath, influencing those around us. In earlier times, people had a deeper feeling for the power and importance of the word to do good or to do harm. Today, real communication through the human voice is being undermined. We are losing both the capacity to carry our inner world out on the waves of our words as well as the ability to perceive the other and their inner world through our senses.
Working with speech activities will enliven and strengthen the organs of speech and the ability to carry living pictures, clear thoughts, and forces of the heart in our words. Teachers who use their voice everyday in the classroom will benefit from this care for speech and learn to nourish their students through enlivened descriptions and storytelling.
This workshop is an opportunity to find your voice and is open to anyone who is interested. All levels of experience are welcome.
Christine Burke currently teaches Communication Studies at Ventura College and Logodynamics/The Arts of Speech privately, in groups, at workshops, trainings, and here at BACWTT. Her passion for words began at a young age and has led to and through theater and English literature, a degree in Linguistics, Waldorf teaching in the US and Sweden, Rudolf and Marie Steiner’s “Sprak Gestaltung,” the Michael Chekhov approach to acting, and an MA in Communication Studies focusing on Communication Education, Classical, and Performance Studies.
Please note that this is an in-person event only. A discount is available for group signups.
Tea, coffee, and snack provided. Please bring your own lunch.

On Sunday, June 14th Claus-Peter Roeh gave a talk on the challenges of AI and computer-centered methods for students and educators. Mary Anne Kirkwood has kindly provided her reflections on this talk.
A thoroughly comprehensive talk on the importance of children’s development in ascertaining their own way of knowing through active engagement and application. As Claus-Peter demonstrated by walking us through the early to middle school years as a Waldorf educator, Know for yourself should be aligned right next to the axiom, Know thyself. And Claus-Peter showed us just how the AI-fostered way of educating fails to do this, across the board.
Unlike what we have in the USA, forward-thinking countries like Sweden and Denmark tried the screen centered and supported education approach which claimed to promote individualized learning in early education, only to discover the drawbacks and severe consequences before making a complete turnaround. Back to the proverbial drawing board, and perhaps in every sense of the term: Human to human is what’s still very much needed. Lessons learned, but would we listen here in the USA?
A thoroughly engaging talk on a very important subject–whether one is familiar with Waldorf education or not, the dangers of too much dependency on AI is very real and Claus-Peter’s talk demonstrated this clearly.
