Holotropic Breathwork by Stanislav & Christina Grof (2010)

A more literal take on this collection's premise, iconic transpersonal power couple Stan (a former mentor, long story ask me about it sometime) & Christina Grof's seminal text on their genuinely groundbreaking modality Holotropic Breathwork is so very much more than a book.

At once a history detailing the practice's creation, a summary of its potential and a lightweight facilitator's guide it grants the near immeasurable benefits of altered consciousness work to the masses. You've obviously heard of what can be therapeutically accomplished with psychedelic assisted work — the Grofs' break the mold of substance and bring this medium to those who have no access to substance, have moral qualms with its use or among others, those who aren't physically or emotionally capable.

Beyond what the book makes increasingly obvious regarding the immense possibilities of Holotropic Breathwork, I think shifting the focus from an external source (psychotropic substance), to an innate and infinite source controlled by manipulating our most basic human function, could not be more poetic or magnificent.

Be careful with this one - I would highly recommend attending an in person workshop if this work is interesting to you and at a bare minimum, working out what is described in the book with a trusted friend.
