Take a look at the following that might be useful to you.
The meaning of sand generally refers to the mountainous areas such as sanitary cave (building base), which is a hill attached to Lailong. Generally, it is low hills or hilly terraces. In the ancient military, the mountain model-sand table was built with sand, and the ancients called the hills "sand". "Notes on Geography and Personnel" said: "The sand maker was given by the ancients, and the mountain shape was made of sand piles, so it was named Sha Er. "In the pattern of feng shui, sand refers to the front, back and left.
The mountains (villages or single buildings) around the city have the respect of TEDA and the backwardness of the city, which is a master-slave relationship. For example, the relationship between dragon and sand and the environmental landscape image of sand in "Mysterious Young Women Capsule Cape Sutra": "The dragon is the monarch and the sand is the minister; The monarch must go up and the minister must go down; Bow your head and walk without losing your temper; The exhibition is strange, and there are auspicious images in the column; Far away, the capital is Guo, and near, there are several cases; Eight winds are guarded by it, and the water mouth is closed by it. "
The Book of Changes says: "One yin and one yang is the Tao", which means that the operation of one yin and one yang is the Tao. Laozi said: "Everything is negative and holds Yang, and it is harmonious to rush." This sentence means that yin and yang are unified in two aspects of things. Because they change endlessly, the harmony between them is conditional, temporary and transitional, so it is relative. Taoism takes "harmony" as its purpose and "harmony" (balance) of all things as its truth, and "balance" is the final state of stability.
Everything in the world can be divided into yin and yang, and everything can be divided into yin and yang. According to the theory of Confucian Yi-ology and the final state of Taoist balance and stability, it depends on "Feng Shui". I think feng shui should also be the principle of "balance", that is, divide the environment around the building into yin and yang, and then define the position of the surrounding yin and yang materials according to the gossip orientation, whether it has reached the gossip orientation balance. If you want to know whether you have reached a balance, you must know what is "Yin" and what is "Yang". In geomantic omen, yin and yang substances are divided into two categories: the positive substance is called "sand" and the negative substance is called "water". So some people call Mr. Feng Shui "Mr. Yin and Yang".
How does feng shui divide yin and yang? Geomantic omen talks about the negative matter, the direction of wind and the direction of water, but it seems that there is no mention of the positive matter "mountain". I wonder how the wind can stop. Wind, like water, will stop when it meets water. Everything is negative and holds yang, and feng shui is divided according to the theory of yin and yang. Water is positive, wind is negative, and water is visible. Where is the wind? I can't see it. But we must know where it is going. How does the wind flow? Is to use the direction of the mountain and the barrier of the mountain to determine the wind direction. The wind came in from there and stopped there. According to this principle, you can choose a "land of geomantic omen". Then we regard mountains and water as yin and yang, "mountain" as yang and "wind" as yin. Because wind and water are intangible and mountains are tangible.
Some people think that "sand" and "water" are divided like this:
Sand: Tall things, burning things, roads, buildings, stoves, etc.
Water: low-lying areas, oceans, lakes, rivers, all places where there is water and flowing things.
Sand: mountains, buildings, trees, walls, piles, towers, chimneys.
Water: rivers, ponds, wells, toilets, fish farming, doors and windows, roads or flat land, etc. I think this statement is not objective.
What are sand and water? Feng Shui believes that an inch high is sand and an inch low is water. Many people often think that the height above the horizon is "sand" and the height below the horizon is "water". This sentence has not been explained, so it is difficult to understand. In fact, this sentence implies a great philosophy. It's about relativity. Whose theory of relativity is that? .
First of all, let's learn about "Qinglong", "White Tiger", "Xuanwu" and "Suzaku". Guo Pu said in "Buried Sutra": "There are four trends in Confucian classics and Japanese classics, and qi comes from all directions. So, there is a dragon on the left and a white tiger on the right. The former is Suzaku and the latter is Xuanwu. Xuanwu hangs its head, Suzaku dances, Qinglong winds and white tigers tame. If the situation is reversed, it should be against the law. Therefore, the tiger crouched and said the corpse, the dragon crouched and said the Lord was jealous, Xuanwu refused to hang the corpse, Suzaku did not dance, the soil returned to its position, and the jade measured its distance. Those who regard branches as dragons and tigers will stop at hills, such as elbows and arms, which is called embracing. Those who use water as a rosefinch will be in a state of decline and prosperity, and they will be afraid of turmoil, which is called weeping. "
That is, Xuanwu refers to the peak in the north, Suzaku refers to the peak in the south, Qinglong refers to the peak in the east, and White Tiger refers to the peak in the west. Not around every building, nor around Mr. Feng Shui. "The left is Qinglong, the right is white tiger, the front is Suzaku, and the back is Xuanwu". It is true that Mr. Feng Shui sits facing south or the building faces the sun. If you face in other directions, this sentence doesn't hold. Looking down at the mountain peak in the direction of Xuanwu, the mountain peak in the direction of Suzaku will sing and dance. The mountain of Qinglong on the left will rise and fall, and the mountain of white tiger on the right will lie in a supple posture. This environment is a "land of feng shui". There is a saying in geomantic omen that "the dragon hugs the tiger out of the county magistrate, and the tiger hugs the dragon and will be poor", which means that the Qinglong sand in the east is higher than the white tiger sand in the west. This is in line with the basic theory of Feng Shui.
So, so we are looking at two directions, which side is "sand" and which side is "water"? There are peaks on both sides. Is it necessary to separate sand water? Of course, everything is negative, praise Yang. The difference between sand and water is the difference between yin and yang. Qinglong Mountain in the east is higher than Baihu Mountain in the west. According to the theory of relativity, Qinglong Mountain in the east is "sand" and Baihu Mountain in the west is "water". We are looking at the contrast between Xuanwu and Suzaku. "The former is high and the latter is low, which is difficult to last for a long time. The latter is high and the former is low. " This is a sentence from The Legend of Golden Lock and Jade. This "back" refers to the north, and this "front" refers to the south. According to common sense, Xuanwu Peak is higher than Suzaku Peak. Are you sure about this? Not necessarily. For example, Xuanwu Peak in the north is close to the tomb or building, and Suzaku Peak in the south is far from the tomb or building. The elevation of the two mountains is similar. Then the north takes the wheel of sand and the south takes the theory of water. So "sand" and "water" are relative, which mainly reflects the central idea of Zhouyi. Without Yin, there would be no Tai Chi thought of Yang. Many people try their best to distinguish yin and yang, listing many related images of what is "sand" and what is "water". In fact, it is better to tell you a way, that is, the idea of yin and yang opposition, relativity.
For example, some people say that "highway" is sand, some people say that "highway" is water, some people say that urban roads are water, rural roads are sand, some people say that the road above the horizon is sand, and some people say that the road below the horizon is water, each with its own merits and thousands of words. A simple "road", a variety of statements. It seems that it should be explained by relativity. For example, there is a "road" in the East. Let's see if it is "sand" or "water". What do you mean? It's like asking, "Do you think this building is tall or short?" I don't think this should be easily defined. Compared with who? Compared with me? Compared with you? So who should we compare with? Asking whether the road to the east is "sand" or "water" is actually asking you about the contrast between East and West. Not compared with the ground level where the building is located. There is a road in the east that is higher than the ground level, so we call it "sand"? Look at the west. Not far to the west, a mountain is much higher than the road. Can the "road" above the ground in the East be regarded as positive material "sand"?
Some people say that "road" is "water" because there are sports cars on the road, and the representative of flow is "water". Let's think about this road with a large flow of people in the north. When we see it, we will "water". Turn to the south of the house. To the south is an artificial lake. Do you still call the highway "water"?
In my Feng Shui lectures, people often mention the problem of "high level". Of course, in order to occupy less land, many tall buildings have been built. There are many masters who choose floors based on the calculation of "years of life". What fate? It is auspicious to choose the five elements represented by the number of floors and be born in the "animal year". I don't think it's accurate. First of all, we must determine what is "high-level". On the surface, we understand that this community is a high-rise building. This means that the buildings in this community are taller than those in other communities, and there is no exact figure. How many floors are considered "high-rise"? This is relative to other communities. Is the top floor of this high-rise residential area the tallest? Perhaps the "top floor" of this community is the same height. When choosing a floor, we should also look at the basic theory of geomantic omen. It is reasonable to have Xuanwu in the north, Qinglong in the east, White Tiger in the west and Suzaku in the south. If this building is the tallest in the high-rise residential area, for example, other high-rise buildings are 30 stories, and this building is 40 stories, this is the real high-rise. Standing on the thirty-eighth floor, looking around, there is no sand that Xuanwu Qinglong can use in the community, and there are no mountains or higher buildings around the community in the distance. So this kind of feng shui is called (coming from all directions), but it is not good feng shui. Is there such a phrase "coming from all directions is absolutely charming"?
In this way, we can understand the basis of high-rise housing selection. No matter how high the floor is, as long as there are green dragons, white tigers and Xuanwu Suzaku around this floor, it is good feng shui. And the number of floors is not very large. Therefore, it is correct to treat the division of yin and yang substances "sand" and "water" with the dialectical thought and relativity of Zhouyi, which accords with the central idea of Zhouyi.
