The contributors examine new findings on safe and skillful work with psychedelic and expanded states for therapeutic, personal, and spiritual growth. They explain the dual process of opening and healing. They explore new approaches for individual inner work as well as for the healing of ancestral and collective trauma. They examine the power of expanded states for reparative attachment work and offer insights on the integration process through the lens of Holotropic Breathwork. The contributors also examine the use of cannabis as a psychedelic tool, spiritual exploration with LSD, microdosing with Iboga, treating depression with psilocybin, and MDMA-assisted psychotherapy for PTSD.
