This is a quote from Bache's book LSD and the mind of the universe, where he compares LSD to 5-MeO-DMT: "In this contex, I will mention that this may be one advantage of the long LSD time window compared with short-acting psychedelics like 5-MeO-DMT. LSD does not blast you through the many layers of the cosmos as quickly as 5-MeO-DMT does, but the eight-hour LSD interface invites/propels/forces a polishing of the consciousness doing the exploring as it is impacted/instructed/healed by the consciousness being explored. An LSD session grinds slow but it grinds fine. It gives us time to be engaged and changed by the realities we are encountering. I think this polishing influences both the eventual clarity of our perception in these states and what we are able to bring back from them, both in terms of healing and understanding." (p. 30f.) What do you psychonauts, who have experienced both substances, think about this statement? I really appreciate this book. I would recommand it to everyone, who is interested in psychedelics for serious spiritual work.  May it be to engage in a psychedelic path towards enlightement or to explore the infinite magnitude of the universal mind. Even only reading about Bache'a LSD sessions feels like purging myself from myself.
