Dear Cecil, I am following the course on-line and I have some questions I would like to clarify: 1- The moving eras for the Pilars of Destiny. ? How this affects the Luo-Shu grid or magic square ? 2- Where can we go deeper on learning about Pilars of Destiny 8 characters / Ba Zi ? 3- When is the day and month considered in the Flying Star Case ? 4- What is the "true" element of Pilars of Destiny ? 5- What house door should be considered ? The site, the Building,or the apartment one? 6- What is the difference between the "9 star" and the "Flying Star" Theories ? 7 - What should I do if my "Ba Gua" number is 9 and my girl 7 ? we are totally and definitively condemned ???
