Psychedelics can act as carriers of information. They temporarily open up pathways in our brain and our consciousness which can lead us to experience what the future in our evolution may entail, one example being telepathy. I have had profound revelations on psychedelics and I am absolutely fascinated with the potential that is contained with the exploration of consciousness. Using psychedelics recreationally is a waste and barely scratches the surface of what can be experienced.
Of course they are not to be used as a replacement for sincere self work, as nothing can replace this foundation upon which we build our spiritual progression. I do not believe that everyone needs to have a psychedelic experience to have a fulfilling life and achieve their life mission.
For those of us who are amongst the members of the shamanic/psychedelic group, it is up to use to utilize these tools effectively and bring something back from the higher levels of consciousness to help benefit ourselves and humanity at large. I have had experiences with LSD, DMT, Psilocybin Mushrooms and the Amanita Muscaria Mushrooms. My personal favourite is the Amanita Muscaria Mushroom.
