Dirk Kruse

Consultant and teacher: differentiated mental observation of nature; spiritual organisational development; inspirational hikes and educational trail to Sense Perception.

Born in Bochum in 1958, Dirk has been involved in the founding of various projects and institutions from an early age, such as youth centres, the Öko-Institut, village reform, Waldorf, social therapy and youth facilities. He has been active as a social therapist for 18 years, and since 1995 he has also been internationally active as an organisational consultant and seminar leader. He has developed methods for ‘psychological observation’, ‘spiritual organisation development’ and many meditative and natural methods of organising and biodynamic farm development.


Dirk Kruse is known for:

Manfred Schleyer

Researcher of the action of forces in nature and technology, in particular on water as a mediator of the etheric and the living. Biologist, educator, Head of the Institute of Flow Science.

Born in 1961 in Essen, Germany, Manfred studied biology, with a focus on micro- and molecular biology. He taught Biology, Chemistry and Computer Science. He has been at the Institute of Flow Science in Herrischried since 2007, researching water quality and its effect on organisms, development processes and shape formation. He works with the rational image research of Dorian Schmidt, and is a member of the Society for Educational Research, a group of active image explorers.

His seminar will explore water questions, the works of the etheric and perception of the effects of the forces, and meditation.

His current research questions are the co-operation of spiritual forces in nature and man during the course of the year, particularly with water as an intermediary.


Martin Hollerbach

Farmer at the Dottenfelderhof.

Martin grew up in Frankfurt am Main (1950) as one of five children. After training as an engineer, he spent some time on the bank staff at Ruhr hospital and on an internship at the Dottenfelderhof for agricultural studies in Giessen, where he gained a diploma. Since 1978 he has worked as a farmer at the Dottenfelderhof. His first responsibility was the cowshed: from there he went on to work in administration, construction, renovation and last marketing. For many years he has undertaken intensive work in the area of image research. He is jointly responsible for the university work in the in Frankfurt Main branch of the anthroposophical society.

In this respect, biologically dynamic and agricultural topics are the focus of his work. But again and again, he finds questions arising about the impact of technology on human nutrition and culture.

In the seminar, we will elaborate the fundamentals of image research and will deal with the perception of the biologically dynamic preparations. In addition, we will turn to close observation of trees as an important theme.

Marianne Kleimann Sevåg

Passionate about education: school founder, nursery teacher, teacher in higher education, coach in adult education – at all ages, Marianne is enthusiastic about personal development.

She has written noteworthy articles, and a book, on the subjects of early schooling and play. Marianne is also active as consultant, translator and managing director of Baldron. Her particular passion is for the invisible essence of nature – see also her translations of the books Elementarwesen Schule (‘Nature Spirit School’) and Die Gaben der Bienen (‘The Gifts of the Bees’) by Karsten Massai. Perhaps it is her Sami ancestors from northern Norway who put the deep connection with the Norwegian landscape into her blood…?

Raphael Kleimann

Raphael Kleimann (Oslo, Norway) is the initiator of the Summer Weeks of spiritual ecology.

Renaissance man by trade, Raphael’s main focus is on healing and inner development, especially with the Baldron MistleTree Essences he has developed. At his healing practice in Oslo and on his travels in Europe, he integrates the transformational power of flower and light therapy with intuitive test methods and scientifically based environmental medicine: detoxing, shielding and building biology counselling, especially radiation and light pollution. In addition, he cultivates contact with living nature through biodynamic horticulture and tree care. His work is directed at physicians and healers, educators and professional flower-essence therapists – but above all for all weary people who are looking for ‘strength in permeability’.

Raphael gives lectures and runs courses in English, German, French and Italian and, of course, Norwegian, focusing on biographical healing with mistletoe, Manichaean practice and the biology of light in today’s wireless humanity.

Andreas Delor (to be confirmed)

Andreas Delor is a Waldorf teacher, researcher and experimental musician who, through music, seeks contact with nature and its nature.

He has been conducting extensive studies on the Atlantis puzzle and the early history of mankind for decades, in order to better understand our own time. In interviews, he brings various spiritual researchers into relationship with one another, based on the latest scientific findings, on the other hand, different from Steiner’s anthroposophical results. Thus, a path through the thickets of existing Atlantis research has emerged, with ever new insights and perspectives. With the protocol of an intensive knowledge-based process, they have surpassed themselves in the 7-volume book series, edited by Andreas: ‘Atlantis – from the Latest Perspective and Science Perspective’ (Ch Möllmann Publishing House).

His contribution to the summer weeks is not a separate course, but is coordinated with the course leaders to enriches shared perception, especially in the second week.

Andreas says:
“I would like to offer in Jotunheim, together with others, a perceptive work on the tremendous character of Sigge / Sigurd / Siegfried – who was responsible in the Lemurian era for the man who was the Saurier (Siegfrieds Drachenkampf) and the human beings who made it possible to experience an ‘I’. In the year 2000 bc. He was incarnated as ‘Sigge’ in Scandinavi, where he found the Nordic ‘Drotten Mysteries’ and encountered Iceland (as described in the Edda) of the Wölwa; who appeared as a ‘Siegfried zu Worms’ around 400 AD, and in the 9th century as the Gawan described by Wolfram von Eschenbach, who defeated the black-magician Klingsor in southern Italy; and not least his presence and task in the 20th and 21st centuries by his appearance in J.R.R. Tolkien’s Lord of the Rings as ‘Aragorn’ and at the same time as ‘Frodo’ (the ‘little Siegfried’ in each of us).

Siegfried plays an ever-increasing role in the present, especially with regard to the ever-clearer incarnation of Ahriman. He is a fighter of Odin (in the Lord of the Rings: Gandalf), and responsible for the surmounting (the dragon fight) of modern man.

The Lord of the Rings is Siegfried’s invitation to modern mankind not to evade, but to face, the death passages – that is to say, the thresholds – which everyone today must pass through – it is the awareness that the salvation of the world from every ‘ little person’(Hobbit):” If you find no way out, nobody will find him”. These threshold experiences, however, are the expression of the ‘breaking-up’ of the ‘new clairvoyant’, for which Odin’s ‘son’ Widar is responsible – Odin, who was killed and resurrected again: in the Lord of the Rings Gandalf falls into the abyss, overcomes the Balrog (the Fenriswolf), dies, and resurrects as ‘Gandalf the White’ (Widar).

Especially in Norway, where Sigge founded the Northern Drotten Mysteries, where Gawan was born as the son of the Norwegian king, Lot, it is necessary to try to perceive the tremendous individuality of the Siegfried in the mythologically contested Jotunheim; to be able to connect with his mission the more intimately. (That this is nothing whatsoever to do with neo-Jewish or even right-wing radical cults cannot be over-emphasised).
