The 10th anniversary of the Trilogos Foundation! With the signing of the documents, Linda Roethlisberger’s life’s work was and will be continued to be recognized and more broadly supported in order to spread the Trilogos®Method not only nationally but also internationally.

We’ve declared 2022 as our year of COOPERATION. That focus has given rise to the launch of the Trilogos Cooperation Network, for which we’ve already been able to recruit a number of experts from a wide range of fields. These professionals were already familiar with and involved with Trilogos and the Trilogos®Method, and are now featured on our homepage. They are: Maren Szepanski, from Berlin; Stefanie Sixt, from Augsburg; Corinne Sonja Grob, from Switzerland; and Rainer Holbe, from Frankfurt.

In 2022, Trilogos also issued, or is issuing, its new MONTHLY IMPULSES—twelve monthly texts (including short exercises) that are published as part of the NEWSLETTER. Closely oriented to the BEACON series, they encapsulate the chapter contents of those books.

Further, we produced the TRILOGOSIANER video series (mostly German), in which we zeroed in on the main individuals behind Trilogos, featuring them both in front of and behind the scenes with interviews. These individuals are: Rita Froehlich, Waltraud Heigl, Rosmarie Gampe, Dr. Michael Noah Weiss and Terry Collins (English).

A four-part interview series with Linda Vera Roethlisberger (German only) was also recorded, offering a more personal and informal insight into the founder’s motives for the emergence of the Beacon series. In the series, the Trilogos founder answers in-depth questions about the titles BASIC TRUST, INTUITION, INDIVIDUATION and CREATIVITY of this series.

Yet another highlight of 2022 was the publication of Linda Vera Roethlisberger’s first textbook in English: THE SENSORY CHANNEL TO THE SPIRITUAL WORLD. Published by tredition, Hamburg, the book is now sold internationally in print format and as an e-book.

In addition, Trilogos has translated the first part its three-part Trilogos certificate training program into English. Published by GRIN, the handbook, entitled Trilogos Diploma Certificate 1: Trilogos Trainer | Handbook, is now available to English-speaking readers.

Both books were translated by Cathleen Poehler, Canada.

In 2022, Trilogos again participated in the 6th Eastern European Conference of Mental Health & 3rd International Public Mental Health Conference, in Zagreb, Croatia. There, Dr. Michael Noah Weiss represented the Foundation with his keynote speech on EXISTENTIAL (PEER) LEARNING ‒ About Experiences on Personal and Professional Development Through the Trilogos®Method.



In 2021, the Trilogos Foundation launched its new short video series entitled Interview Pearls. The first interview called »Life experiences«, had been held with Michael Noah Weiss in 2018. The series is designed to showcase valuable contributions of a wide range of individuals from their respective fields of activity on a monthly basis. So far, Interview Pearls has published interviews with Prof. Dr. Germain Weber, Prof. Dr. Michael Noah Weiss, Linda Vera Roethlisberger and Reinhilde Burg.

In addition, the Foundation has been promoting the Trilogos®Method with a brand new format: TRILOGOS LIVE, a monthly digital media evening event. Hosted by Michael Noah Weiss, the events are subsequently made available on the Trilogos YouTube channel.

A further highlight of 2021 was the publication of the four books from Linda’s new Beacon Series. Published by tredition, they are available in both German and English as hardcovers, e-books as well as audio books and consist of the volumes: 1 On the Path Towards Basic Trust | 2 The Path of Intuition | 3 Individuation ‒ On the Path To and Beyond One’s Self | 4 Creativity ‒ The Power of Change.

Moreover, the Trilogos Foundation participated, for the fourth time, at the 5th International Eastern European Conference of Mental Health. Representing Trilogos, Michael Noah Weiss held a lecture at the event, held in Zagreb from September 30 to October 2.

The Trilogos Foundation has been involved with the ETH Foundation / Zürich, where it has established the named fund entitled “Linda Roethlisberger / Trilogos Fonds” in order support young people in their personal development with the Trilogos®Method. As part of ETH Week 2021 (September 12‒17, 2021), Trilogos took part for the first time, with a keynote by Prof. Dr. Michael Weiss, in the Knowledge Fair held on the Hönggerberg campus as well as with a Trilogos booth and as a participant in the symposium held the Balgrist University Hospital.

Finally, in 2021 the Trilogos Foundation was also proud to be able to recommend the publication Daimonic Dialogues, by Michael Noah Weiss. The book presents the experiences of some twenty students at a Norwegian adult education school with Trilogos guided image journeys.
