costa's book 'the watchman's rattle' ends with costa proclaiming that 'insight' is the key to saving civilisation, the very thing which plant medicines can help us with. insight is a function of the brain she suggests, it's been mapped by science who love to put things in the box and the best way to bring it on is by keeping the brain healthy, so she lists things to avoid and things to do, stuff you all know, stuff we do. however she suggests 'mind gyms' a new fad sweeping through smart communities in la. man all costa needs to do is drink ayahuscia and let her in. more insight than you really need. that will fix her up. she concludes by saying imagination is the most powerful tool to generate insight and thus against civilisation crumbling, the realm of the magickian will save mankind.
