Thank you very much for taking the time to write such detailed and comprehensive explanation. I understand perfectly and I totally agree.
Primary colors (bright red, green, blue and yellow) and pastel colors.
If I choose to see bright pink as fire and pale pink as earth, that's my personal decision, but a primary color will always be considered first, acknowledging also BaZi.
Yes, many authors and websites make use of people's fears and push "magical" objects to buy from them. "OMG #5 is in this sector this month. Choose to buy from our Feng Shui Supermarket a rotten tomato, an oversized rhynocerous or a frog that talks to exhaust the malicious star and bring you wealth"
Never bought and don't plan to do so from these, like you said in another article, Fast Food Feng Shui.
Also I wanted to ask about Tai Sui (Grand Duke Jupiter), San Sha (Three Killings) and Sui Po.
I've read about how every year they sit in different directions and recommendations are given like to sit, not to sit, to face, confront, not to confront, not to disturb, no renovations, ground breaking etc. besides the usual selling technique: "here buy this product to help you neutralize"
Are these to be considered when applying Feng Shui (to sit, not to confront, no renovations etc.) or they have no real influence and it is to be considered another scare tactic used to sell products?
