在《易經》里单数为阳, 双数为阴. 我曾怀疑马来西亚政府也会用《易經》因为马来西亚人民身分证号码的最后一个号码如果是单数那这个人是男性, 而马来西亚人民身分证号码的最后一个号码如果是双数那这个人是女性.
其实我们的手指已经把宇宙的这个密秘告诉我们了, 看看你的手指, 我们只有一个母指, 单数为阳, 但母指里有两个关节, 双数为阴;因此阳中有阴.
而另外的四个手指, 四为双数, 双数为阴, 但这四个手指都是三个关节; 4里面有3, 因此阴中有阳.
《易》字是由日和月形成, 象徵阴阳. 整六千年前的伏羲氏, 当时人类并没有文字, 他们已知道世界上所有的东西都是由阴阳组成的, 后来科学家发现这世上的东西都有阴阳之分.
世界上所有的东西都是由阴阳组成的, 必须要阴阳互相配合才行, 失一不可. 世界上最大的事情就是宇宙。宇宙由正能量+ ve和负能量-ve形成。以我们的太阳系为例，太阳拥有正能量，因此它具有磁能，使有负能量的九个行星能够绕过它。反之亦然，世界上最小的事情是原子, 原子也由质子proton 和负离子electron质子; + ve和-ve能量形成。 + ve和-ve能量就是阳和阴。
此外，以我们的智能手机为例，阳+ ve是你可以看到的，而-ve 你是看不到的东西。你的智能手机只是一个硬件，这是一个阳; 但没有电，软件或你看不到的应用程序，它是不能运行。
动态（移动）为阳+ ve，静态（空闲或停留）为yin -ve。山不动，就是阴; 河流是阳+ ve。热是阳+ ve，冷是阴。明亮是阳+ ve，黑暗是阴-ve。
一个人不可以太阳太刚烈, 或太阴太柔弱. 在风水学里, 太”阳”的地方不利我们, 太阴的地方也对我们不利. 如果你住在太热的地方, 你感到不舒服, 同样的地如果你住在太冷的地方, 你也会感到不舒服. 人类最适合住在不太热也不太冷的地方, 那就是阴阳互相配合, 因此风水学也是环境学. 它所强调是从大自然环境学习如何生活; 学太极拳的师父们最了解其中的道理了, 因为太极拳是柔中带刚, 其实太极拳也原自于《易經》. 《易經》不是仅仅是本占卜的书, 它包罗万象. 它告诉我们一个重要而简单的道理, 那就是阴阳必须互相配合. 如果世界上只有阴, 女性而没阳, 男性那怎能传宗接待呢?
太多或太少是不好的。水能载舟, 也能覆舟; 水可以行舟，但水如太多或太强，水将推翻一艘船。平衡是关键。物极必反, 中庸之道.

to have a better understanding about this topic.
The oldest book in the world is neither Quran nor Bible or anything related to religion. It is a book nothing to do with religion. This book is I-Ching. I-Ching has existed in the world for more than 6000 years. It is very primitive. During that time, there were neither proper spoken languages nor written languages.
In I-Ching, the odd numbers are regarded as Yang, even numbers as yin. I always wonder whether is the Malaysian Government apply I-Ching too as the last number of the identity card number of the Malaysian is odd for man, while even number is for a woman.
Odd number = Yang; Even number = Yin
As the matter of fact, our fingers have told us the secret of the universal long ago. Look at your fingers. There is only one mother thumb and 1 is yang but in the thumb there 2 joints and 2 is ying. It means there is yin inside the yang and it is the “balancing”.
Whereas, the rest 4 fingers are yin but all have 3 joints in them. You can find yang inside the yin and again it is balancing.
The word I 易in I-Ching is formed from the Chinese words yin and Yang日 Sun and 月 Moon. 6,000 years ago Fuxi knew everything in the world is formed by the positive and negative energy. Later scientists discovered that the distinction between yin and yang, everything in the world, by the smallest of the proton and electron in Atom to the largest in the solar system the Sun and the planets of the universe, are all made up of the yin and Yang.
The largest thing in the world is the Universe. The Universe is formed by +ve and –ve energy. Taking our Solar System as the example, The Sun has +ve energy and hence it has the magnetic energy to make the 9 planets which have –ve energy to go around it. Vice versa, the smallest thing in the world is the Atom and Atom is also formed by +ve and –ve energy which are the proton and electron. +ve and –ve energy are yang and yin.
Also, taking our smart phone for example, yang +ve is something you can see and -ve is something you cannot see. Your smart phone is just a hardware which is the yang +ve but without the electricity, software or the app which you cannot see, yin –ve , it cannot function.
Human being is another example of yin yang. You can see me as I’m hardware, yang, +ve. But you cannot see my soul, feeling and thoughts which is the software, yin and –ve.
Dynamic (moving) is yang +ve and Static (idle or stay still) is yin –ve. Hill does not move, it is yin, -ve. River flows is yang +ve. Hot is yang +ve and cold is yin -ve. Bright is yang +ve and dark is yin -ve.
Einstein developed the theory of relativity. It is actually the theory of yin yang. In feng shui, or any other proven philosophies is talking about balancing of both yin –ve and yang +ve and that is the Key of the world.
All things in the world are made up of Yin and Yang. Yin and Yang must complement each other. A person neither can be too stubborn (yang), nor too soft (yin). In Feng Shui, a place where the hot Sun is always shining at is unfavourable and it causes too much of yang energy. If you live in a very hot place, you feel uncomfortable. Vice versa, if you live in a very cold place, you will feel uncomfortable as well. The most suitable place for human living to live is a place neither too hot nor too cold, and that is compatible with Yin and Yang. Feng Shui is in fact subject about the environmental science. Tai Chi masters are those who know how that goes, because Tai Chi is in compliance softness with rigid. Tai Chi is also originated from the theory of I-Ching. I-Ching is not just a book of divination, it covers quite a lot. It tells us an important and simple truth, that is, Yin and Yang must complement each other. If there are only men in the world, without women, how can we have the reproduction?
Too much or too little of anything is bad. Water can sail a boat but too much or too strong the water will overturn a boat. BALANCING IS THE KEY.
