The Way of the Psychonaut explores the life and work of Stanislav Grof, Czech-born psychiatrist and psychedelic psychotherapy pioneer. Stan’s quest for knowledge and insights into the healing power of non-ordinary states of consciousness, influenced the discipline of psychology and profoundly changed many individual lives. One of those transformed by Stan is filmmaker Susan Hess Logeais. The documentary utilizes Susan’s personal existential crisis as a gateway to Grof’s impact, from the micro to the macro.
