The European Institute for Inner Science (established by the Inner Nature e.V. non-profit association), is an interdisciplinary research and practice institute dedicated to integrating ancient yogic wisdom with modern scientific research. Our institute strives to integrate classical Indian Hatha Yoga practices with established tools of psychosomatic medicine, aiming to support holistic mental health and wellbeing in clinical settings.
By combining Isha Upa Yoga with current research, the European Institute for Inner Science opens up innovative, evidence-supported approaches to the treatment of psychosomatic disorders. Our vision is to bring scientifically validated, alternative treatment methods into modern clinical practice — bridging tradition and science to enhance general health and inner wellbeing.
What We Do
Science & Research
We conduct clinical studies to examine the effectiveness of mindfulness-based, inward-directed treatment methods – such as Isha Upa Yoga (modules based on specific coordinated movements, breath and meditation) – combined with various tools of psychosomatic medicine.
Integration into Clinical Systems
We support specialized medical centers in implementing holistic treatment concepts combined with Isha UPA Yoga.
Raising Awareness
We foster dialogue between science, therapy and classical yoga, aiming to raise awareness of yoga’s relevance in modern scientific and psychosomatic therapeutic contexts.

Isha Upa and Hatha Yoga
