In addition to our personal experience with the darkness retreat, together we bring more than 30 years of combined experience from inner work traditions spanning East and West, including 25 years as students of the Diamond Approach, a sophisticated contemporary path integrating modern depth psychology with Eastern contemplative methods.

Gunnar Gjermundsen

Gunnar’s passion is bridge-building from the insights and practices of ancient wisdom traditions, both East and West, to the concerns and needs of human beings in contemporary society.


Educated as a psychologist at the University of Oslo, he found he needed to supplement his clinical and empirical training with a 3,5 year’s (1000-hour) comprehensive yoga teacher training at the Norwegian Yoga Teacher Academy, working in-depth with systems of tantric meditation, the yoga of Patanjali as well as Hatha yoga, in the Satyananda lineage.


These years put him on a trajectory of inner exploration through the Diamond Approach path as well as various systems of Tibetan Buddhist meditation under the guidance of Dr. Daniel P. Brown and Dr. Alan Wallace. 


Gunnar has a long-standing interest in the Western philosophical tradition through BA studies in philosophy at the University of Oslo and the University of Toronto, and he is currently undertaking his MA studies in philosophy at UiO, focused on late antique Greek patristic thought. 


Over the last four years he has been training as a group analyst at the Institute of Group Analysis, Norway.


Gunnar is currently working in private practice as a therapist in Oslo with individuals and groups, in addition to teaching yoga and meditation classes, as well as workshops in bioenergetics and breathwork. He regularly teaches week-long yoga retreats in a beautifully restored Benedictine monastery in Umbria, Italy.
