Grof is recognized for supervising thousands of LSD sessions, mapping the human unconscious in ways that succeeded the work of Freud and Jung.
The work provides a comprehensive "map for the inner frontier," covering Grof's 60-year career.
The core focus is on "holotropic" states—meaning "moving toward wholeness"—accessible through psychedelics and Holotropic Breathwork .
Critics and scholars consider this Grof’s greatest contribution, delivered in an easy and accessible tone despite its depth.
