This module offers an exciting exploration of the philosophy, principles, and strategies underlying the experience and practice of Holotropic Breathwork®. Topics covered include: the power of the Inner Healer and moving towards wholeness; presence: the disciplines required to become an effective Holotropic Breathwork® practitioner; COEX’s: how the Inner Healer orchestrates transformation through our experiences of the psyche; exploration of the frontiers of the psyche through Movie Yoga; session stories: valuable teachings from practitioners through their work with breathers; open forums focusing on every facet of the Holotropic experience; dance, medication, music journeys and nature celebration.

Open to anyone interested. Previous experience with Holotropic Breathwork® is not necessary.

Each participant will have two sessions of HB as an experiencer, or “breather,” and two sessions as a partner, or “sitter”. Besides the breathwork sessions and the topics covered (described below), there will be art, music, dancing, film, and integration during the module.

In addition to Holotropic Breathwork® breathing and sitting, topics explored in these modules are especially relevant for anyone working with others in expanded states of any sort for transformation and personal healing.

Dory Perry

Dory Perry

Dory Perry (teacher, module facilitator) began her journey with Holotropic Breathwork® in 2001, after attending a weekend workshop, led by Stan Grof and Tav Sparks. On the heels of a cancer diagnosis and driven by the need for meaning and a more expansive perspective, her experience was profound and life affirming/altering. She began attending weeklong Grof Transpersonal Training (GTT) modules, integrating the work into her life as an ongoing spiritual practice and developing a deep trust in the work and in the inner, ancient wisdom within each of us. In 2005, she was certified as a Holotropic Breathwork® facilitator. As a GTT staff member, she regularly serves on facilitating teams for residential training modules.

Dory has an MSEd, with a focus on writing and literacy. A writer, musician, and filmmaker, she has spent much of her life working in the arts and has a particular interest in the power of writing, sound, and visual storytelling as healing and integrative practices. Originally from the tropics, she now resides in Pittsburgh where she works in higher education and provides ongoing Holotropic Breathwork® workshops.
