Feng Shui Independent of Zi Wei Dou Shu (ZWDS) And Ba Zi (4 Pillars)? Part II

In my previous article, we talk about the dangers of using Feng Shui to improving one's life without considering the destiny of this person that is brought about by his time of birth and that destiny is a zero-sum game.
How important then are Ba Zi (4 Pillars) and Zi Wei Dou Shu (ZWDS) towards the execution of Feng Shui? Is it enough to know entry level Chinese Astrology to the extent enough for him to know this client will have health problem and his Feng Shui is tuned to avoiding health problems? If this Geomancer knows only entry level 4 Pillars and ZWDS, it is safe to say he does not know how much allowance he have in the rest of the aspects of life (wealth, career, romance, marriage, children) to re-allocate amongst in this zero-sum destiny game.
The result? Either death, bankruptcy, lose job, divorce if this practitioner is aggressive in his Feng Shui approach.
Otherwise, a life of mediocrity for the client if this practitioner is conservative in his approach.
Neither of which bodes well for a paying customer.
Is it sufficient then for a Geomancer to be well-skilled in either Ba Zi or Zi Wei Dou Shu? From an ethical stand point, I would say no again because a Feng Shui practitioner's work could result in dire consequences like death or rape for a client whose destiny is skewed towards such possibility.
This is not an exaggeration because I have indeed come across cases of Feng Shui audit exacerbating death or rape because these practitioners do not know Zi Wei Dou Shu.
What Fengshui setup these practitioners have to amplify wealth unwittingly brought about other undesirable outcomes.
The next time you intend to engage a Feng Shui consultant, do check if he also knows Ba Zi and more importantly Zi Wei Dou Shu.
Ask whether his methods include Zi Wei Dou Shu inspired methods.
