Voyage aux confins de l'esprit

Really wonderful information, but I don't understand why they weigh so heavily on mysticism when we have a lot of scientific understanding how spirituality works. Our brains have a mechanism that is a bit of a slider switch between "self" and "no self". The more we live in fear, anxiety, focus, the more we trend towards "self" because it is precisely linked with survival - if you don't focus on "self" then you are less likely to survive in the wild. Psychedelics throw the switch the other way and make us forget about ourselves as individual beings, which much like religious experiences, makes us feel "one with all". It's not magic, it's an evolutionary mechanism. Wish they would talk more about the science we already have.
