Invitation to Participate in a Research Study at the European Tantra Festival

Dear Participant,

My name is D. Vaughn Becker, and I lead the Technologies of Transcendence research initiative at Arizona State University. I’m writing to personally invite you to take part in a unique and meaningful research study taking place in connection with the European Tantra Festival.

Our broader mission is to better understand how powerful contemplative and embodiment practices such as meditation, breathwork, yoga nidra, and increasingly tantra shape human physiology, emotion, and well-being. These practices have been explored for centuries, but we are only beginning to measure their effects with modern tools.

This study represents an important step in that direction.

For the first time, we are focusing specifically on tantric and relational embodiment practices—approaches that work not just with attention and relaxation, but with connection, energy, and deeply personal forms of experience. These are domains that have historically been difficult to study, in part because they are so intimate and, at times, culturally misunderstood.

At the same time, we now have access to wearable technologies that allow us to observe something remarkable: how these experiences may be reflected in the body’s regulatory systems.

In particular, we are interested in heart rate variability (HRV), a widely studied indicator of autonomic flexibility and resilience. Higher HRV is associated with better stress regulation, emotional balance, and long-term health. In simple terms, it offers a window into how well the body can adapt, recover, and integrate experience.

This study asks for simple wearable metrics if you have them. If you do not have a wearable, we still warmly welcome your participation. We have prepared a second option that involves a short set of cognitive tasks that test how well you can focus attention. You may also complete the cognitive option and report wearable metrics if you wish; that combination gives us the richest data and helps advance the science most.

Our goal is to explore whether participation in an intensive, immersive festival environment—especially one centered on tantra and embodiment—can produce measurable shifts in these systems, not just immediately, but over time.

This is where your participation matters.

By contributing a small amount of data—simple wearable metrics and brief reflections—you help us build one of the first datasets of its kind. A dataset that respects the depth of these practices while bringing them into dialogue with contemporary science.

We are approaching this work with great care and respect. Your privacy is central. All data are de-identified, and you will have full control over what you choose to share.

This is not just a study about numbers. It is an effort to better understand how profound human experiences—connection, presence, embodiment—translate into measurable changes in health and well-being.

If successful, this work has the potential to:

• Advance scientific understanding of tantra and embodiment practices
• Bridge contemplative traditions and physiological science
• Contribute to new approaches to stress, resilience, and mental health
