I haven't read "The Ancient Secret of the Flower of Life" but I will search for it now :)
My best advice if you want to go deeper in the rabbit hole is to take a compass and start drawing there you will find a lot of answers and even more new questions. Take one dot because dot(Bindu) is beginning of everything, then draw a circle around it, on that circle take another random dot and use it as a center of next circle. Now you will have Vesica Piscis and from there just let your imagination to lead you. ❤❤❤
