If we try to formalize the words that I have underlined, I am afraid that everyone will come to an individual result and it will be philosophical and not practical. This is what I wrote about - those people who use feng shui see it as a specific meaning for themselves and it works for them. If you try to transfer it to another person who has different views, then most likely he will say that Feng Shui does not work.
We are all superstitious its inherent to us as human beings, even if it is not Fengshui like shamanism or any religion they will always connect something into it to have good luck and be guided in a path of uncertainty, but Fengshui is not only about superstitious like what I've been saying it has something to do with harmonious and clear thinking, I do believe in Fengshui but I am not a serious practitioner but I notice people who seriously practice Fengshui are happy, clean people and very meticulous on how they place things and check up dates for their activity.
