Feng Shui is Science and Mathematics.

The more I understand about feng shui, the more I think that Feng Shui is Science and Mathematics.

As what I always said, the I-Ching or yi jing 易经 is a very scientific book and many of the scientific theories today are actually in-line with the theory of the I-Ching 易经 even though the I-Ching 易经 has existed in this world approximate 6000 years ago. It is the oldest book in the world and it is in fact like a 无字天书 (a book from the heaven that cannot be explained by words).

 As a matter of fact, bagua, a valuable product from I-Ching 易经, one of the great recovery of men, (Chinese: 八卦; literally "eight symbols") is an eight diagrams used to represent a range of interrelated concepts. Each consists of three lines, each either "broken" or "unbroken," representing a yin line or a yang line, respectively. Yin is referring to the negative energy and the yang is the positive energy. Bagua is the result of the ancient Chinese binary system. Each of the Gua is consists of three little Yao symbols, which is equivalent to a bit in today's binary language. Each Yao (section) represents either Yin (0), female or Yang (1), male force of nature. Yin (0), female, is two short little hyphens with a gap in between. Yang, male, is one continuous hyphen-like line. Use some graphic imagination to help you remember the female and male symbols or you can fashionably call them "zero (Yin)" and "one (Yang)". Due to their tripartite structure, they are often referred to as "trigrams" in English.

If you refer to my book http://www.penangfengshui.com/index.php?pages=book_enjoyyourlife_ebook page 130,

 You will find that the numbers in the ‘later heaven bagua’ will add to become 15 whether you add the numbers vertically, horizontally or diagonally. The no 5 which is the 5 yellow is right at the centre of the bagua and hence it is the most powerful star as it controls all other numbers in order to add up to become 15. It is the King of the table which rule and control.

I said it repeatedly during my speech that there are a lot of valuable knowledge can be obtained from the bagua. The bagua has correspondences in astronomy, astrology, geography, geomancy, anatomy, the family, and elsewhere. The no 5 is the earth (yellow) which represents the piece of land (earth) of China 中国大陆 which was believed to be located at the centre of the world. The yellow color used to be the official color for the emperor. In the olden day’s 封建時代, normal citizens were not allowed to use the color except the King. It was believe that the whole piece of land was belonged to a person solely i.e. the King.

Therefore, we have to take good care of the 5 yellow. As our Earth does not stop revolving, the magnetic energy of the Earth will not be the same all the time. Every 20 years, there will be a change of period (yun) and 1984 – 2003 is the period 7 and the number star 7, 8 and 9 are good, especially the number 7. 2004 – 2023 is the period 8 and the number star 8, 9 and 1 are good, especially the number 8 and it is a star in power currently 得令星. My article http://penangfengshui.blogspot.com/2013/09/impact-of-planets-to-our-life-path-and.html explained the reason for the change scientifically and also its calculation mathematically.

If you define the number 8 as Najib (King) who is ruling, then number 5 is Mahathir (太上皇; a title assumed by an emperor's father) who used to be very power. The number 5 star is not in power presently 失令星. Mahathir is not in control now and in order to exercise his influence, he has to make a lot of noise in order to obtain the attention of others. Thus, wherever number 5 star appears in a place, it will create trouble to obtain the attention of others. This year, according to the annual flying star chart, the no 5 is at the centre of the chart, hence, it is not a good year with lots of disasters, typhoon, flood, , diseases, earthquake and there centre of the Earth, the Middle East is not the peaceful state anyway.

You will find that number 5 is a very important number in Chinese. Why are there 5 elements, 五行, (plant, fire, earth, gold and water) but not 4, 6 or 7 and etc elements because without 5 we cannot the relationship of 相生相克mutually reinforce and neutralize each other?

Also, with the five elements, we can have the relationship of the plant or wood produces the fire but counter the earth and so on. If there are 6 or 7 elements, it cannot form the links and relationship.

There are many examples to show the number five 5 is an important number as following:-

1. 五福临门的五福wu fu为长寿, 富贵, 康宁, 好德与善终longevity, prosperity, healthy and peaceful, passionate and good ending of lif
