Marc B. Aixalà (module teacher and facilitator) is a Telecommunication Engineer and Psychologist with Master studies in Integrative and Strategic Therapy. He has been trained in the therapeutic use of Non Ordinary States of Consciousness. Also trained in MDMA assisted-psychotherapy for PTSD by MAPS and the use of psilocybin for treatment-resistant depression, Marc is now working as a therapist in a clinical trial with psilocybin in Sant Joan de Déu Hospital in Barcelona where he also mentors other psychedelic therapists. He has experience as a Team Leader and Trainer in emergency psychological assistance for people going through difficult psychedelic experiences at Boom Festival (Kosmicare 2010-2016).

Marc is the author of Psychedelic Integration: Psychotherapy for Non-Ordinary States of Consciousness (2022).

Marc collaborates with ICEERS (International Center for Ethnobotanical Education Research and Service) by offering integration psychotherapy sessions for people in challenging situations after psychedelic experiences, developing theoretical models of intervention and training and supervising therapists. He is the author of “Psychedelic Integration: non-ordinary logics and the challenges of psychotherapy in expanded states of awareness”.

He works as a psychologist in his private practice in Barcelona and offers trainings, lectures and talks related to psychedelic psychotherapy and integration.


In recent years, we have witnessed a renewed interest in psychedelic therapy and research being called “the psychedelic renaissance.” Many people are discovering the potential benefits of psychedelic substances and master plants, and shamanism has become an increasingly sought method for healing. Dozens of clinical trials study the efficacy of psychedelic medicines such as MDMA, psilocybin, and ketamine to treat serious conditions like PTSD and treatment-resistant depression. At the same time, the importance of Stanislav Grof’s Holotropic Paradigm and of Holotropic Breathwork® in the development of the psychedelic field still remains unknown to many. With respect to this new era of psychedelics, those of us involved with the Holotropic paradigm have much to contribute and consider. How do psychedelics compare with or compliment Holotropic Breathwork® as tools for personal development? What is the role of Holotropic Breathwork® now that psychedelics are becoming an accessible therapeutic method? What are commonalities and differences and what is it that the Holotropic approach has to offer to the individual process in comparison to psychedelics?

In this module we will explore in depth: 

  • The different paradigms in which psychedelics have been used, and are currently used. 
  • General characteristics of the main psychedelic medicines and the process they induce. 
  • The use of psychedelics from the Holotropic Paradigm developed by Grof, Sparks, and others. 
  • How do psychedelics compare to Holotropic Breathwork®? 
  • The principles of supporting processes from the Holotropic perspective. Dealing with challenging situations. 
  • The importance of integration of psychedelic experiences.

Holotropic Breathwork®


Holotropic Breathwork® is a powerful technique for self-healing and self-exploration allowing for greater self-understanding, expansion of self-identity and access to the roots of emotional and psychosomatic challenges one might face. Holotropic Breathwork® comes from the Greek words ‘holos’ (whole) and ‘trepein’ (going to) meaning moving towards wholeness.


GTT is a program for experiencing and studying Holotropic Breathwork® and the transpersonal perspective. It is a two-track program that can be used either to become a certified practitioner or simply to experience this practice in a more in-depth format. It is the best way to spend time with HB co-developer and one of the founders of transpersonal psychology, Stanislav Grof. Although semi-retired, Stan still teaches at some of the six-day training workshops, also called modules.
