Is Bazi Necessary to do Feng Shui?

Here's what Master Joesph Yu has to say:

Should the Four Pillars be an indispensable tool in Feng Shui studies? The answer is "No!".

Four Pillars of Destiny deals with Heaven Luck. It tells us what is ahead of us in our path of life. It gives us suggestions to handle situations in the future. One of the ways is to use Earth Luck, that is, Feng Shui. The other way is the appropriate use of Man Luck.

Another question is, "In prescribing Feng Shui cures, should we take into account the four pillars of the occupants so that the right elements are assigned?" The answer is a simple "No!". Is this answer shocking? Ask yourself, "If water is my most unfavorable element, should I stop drinking water?" Is the answer obvious? What more intimate relationship between yourself and water than letting water into your body? It is simply a misconception and misunderstanding of the five elements theory to try to use objects and substances to balance the four pillars. Feng Shui and Four Pillars are divided into different levels. In the basic level, we may be using colors and substances to balance our Four Pillars. Since it is not harmful and may be beneficial in a psychological sense, it can be recommended.

By the way, I have known that Bazi is never mentioned in the ancient Feng Shui scriptures. However, it is a common practice among many practitioners to utilise it to aid their analysis. Anyway, here's a quote on this from Johnny Chan, a Xuan Kong Master from Hong Kong:

"坊間人們都產生了一大誤會，以為懂看命理運程的，都應懂看風水，此眾人之誤解的確難為了很多「師傅」，原本未有進修風水的，都要「求求其其」，學些形家、八宅，想著馬馬虎虎，應酬兩句，便可蒙混過關。"

 An update in 2021: After so many years since i wrote the above, the answer is still no BUT if one is able to utilised solutions from Bazi or Vedic astrology simultaneously, then the effects can be many times better instead of solely relying on fengshui alone.
