This is a beautiful book, a pleasure to read. Much lovely art. The only sacred geometry book my wife has picked up and read.
This is definitely the most accessible sacred geo book I own. Another 2 houseguests just picked it up and spent the week reading it.
There is a narrative here about how the world arises through the interplay of number, but it's light and really what's worthwhile here is just the images created by one of the modern masters in this field.
In fact let that be a lesson to all of you who would study this field-- narratives, discursive analysis, words, are all well and good but the core realizations come by doing. So seek inspiration here, but do something.
