Psychedelics are powerful amplifiers of consciousness. Used responsibly, they can deepen spiritual practices and accelerate therapeutic processes. They have the potential to transform and enlighten, teach and heal. They connect us to our senses, bodies, feelings and intuition. They connect us to each other, to Nature, to the Cosmos, to God. They balance the brain hemispheres and weaken the default mode network. They probably helped us evolve into human beings (the Stoned Ape hypothesis) and will in all likelihood help us evolve further into spiritually enlightened beings.
People are afraid of psychedelics because they are so revolutionary. They must be handled with care. But ultimately, if used with intelligence and maturity, the benefits far outweigh the risks. Ultimately, who dares wins.
