Around the time I was learning of the sacred mushroom metaphor in John Allegro's harshly attacked Aramaic, Hebrew and Greek translations of the Dead Sea Scrolls by the Vatican I made the leap in the book of Genesis as an allegory for prevention of humanity having entheogenic experiences. John Lash takes it one step further and points out the logic flow of the priesthood not only creating an intermediary position for themselves between man and source but also that they are terrified of the experience themselves.
In addition John explains in the first part the lifeless logic behind the pursuit of the transhumanistic path which is if we consider it properly must be a neurotic fear of death concrete evidence of not actually living in the first place.
There's lots more but I like to tap a few words out to give a feel for the content.
