Chris Bache wrote the book "LSD and the mind of the universe" (2019), where he speaks about his 73 high-dose LSD sessions over the course of 20 years. If you are interested in following a psychedelic path toward enligthenment (or more), I really recommand you this book.

Here is the text from the cover:
"On November 24, 1979, Christopher M. Bache took the first step on what would become a life-changing journey. Drawing from his training as a philosopher of religion, Bache set out to explore his mind and the mind of the universe as deeply and systematically as possible--with the help of the psychedelic drug LSD. Following protocols established by Stanislav Grof, Bache’s 73 high-dose LSD sessions over the course of 20 years drew him into a deepening communion with cosmic consciousness.
Journey alongside professor Bache as he touches the living intelligence of our universe--an intelligence that both embraced and crushed him--and demonstrates how direct experience of the divine can change your perspective on core issues in philosophy and religion. Chronicling his 73 sessions, the author reveals the spiral of death and rebirth that took him through the collective unconscious into the creative intelligence of the universe. Making a powerful case for the value of psychedelically induced spiritual experience, Bache shares his immersion in the fierce love and creative intent of the unified field of consciousness that underlies all physical existence. He describes the incalculable value of embracing the pain and suffering he encountered in his sessions and the challenges he faced integrating his experiences into his everyday life. His journey documents a shift from individual consciousness to collective consciousness, from archetypal reality to Divine Oneness and the Diamond Luminosity that lies outside cyclic existence.
Pushing the boundaries of theory and practice, the author shows how psychedelic experience can take you beyond self-transformation into collective transformation, beyond the present into the future, revealing spirit and matter in perfect balance."
