风水房屋坐向怎么看？ 坐向怎么看 ？房屋坐向怎么看？ 如何看房子的坐向？

以上问题，定坐立向在玄空飞星风水学上，被视为一大课题，原因是未能够弄清楚其法。 纵使其他学理清楚明白，亦属枉然。 简单来说，因为不能明其学理，就是不能起出正确之飞星盘。 对初学者而言，定坐立向就是门向，看似简单，其实未然。 其间所含之学理，错综复杂，只有从其基础着手，方能领会。

何者为屋？ 有屋顶，四面墙壁，有门，有地基便为屋。 此为建成房屋之基本条件。 所以谓，如果缺其一者，便不能称之为屋。 例如少了屋顶，剩下的墙壁会变成围墙; 少了墙壁，剩下的屋顶和地基会变成亭台等。 成屋及不成屋对玄空风水学极为重要，因为够条件成屋者，才能得以纳气。 其房屋才有风水之产生。

'坐'者 即为背 / '向'者 即为面

所谓有背即有面，有坐必有向。 两者关系必为180度。 在二十四山向盘上，向者必为坐者之对待。 但在房屋之真实建筑中，很多时候在门之对待未必是屋之墙壁，有可能是窗，亦可能是后门等。 在风水学理上，亦为坐为背也。

门为纳气口

风水学上理气口诀之「随地而行」，说明了风水之理气是在地面流动的，它行经新建成房屋的缺口时，即门，进入屋内，再流走八方。 此行为对房屋而言，是为纳气。 而纳气之过程，房屋大门便扮演了一个很重要的角色。 由此推断，没有门之建筑物，理气不能使它纳气，又衹有门而没有建筑物，像离笆，围墙等，亦是没有纳气的机会。

门向

风水理气入屋而流走八方，像前段所述，缺了屋顶或缺了墙璧的房屋，便不能顺利纳得理气了。 而门向之角度，便绝对地影响了所纳得理气之好坏。 像门向之一百三十五度，便跟一百四十度，会产生了很大的差异。

屋之纳气

风水理气流走入房屋后，便在房屋之中心点立极而静，从中心点再放射宅内八方。 除非房屋之阳基形状日后有所改变，要不然，一般之立极中心点不会轻易被移动的。 然这房屋便已立极纳气，所以在这已纳气的空间内的再建空间，像房屋内的房间，浴室等，是不会重新纳气成其他卦盘的。

大立极与小立极

试想一下，如在房屋内有三，四个房间，其道理一样，房门亦绝不会各自纳气的。 房间内小立极所纳得的理气，亦即是房屋内大立极等同之理气而已。 房间内小立极之立极中心点，亦会因应房间之形状，立极而静，一样不易被移动的。

楼层纳气

如此法理之伸延，当房屋加建二楼，二楼亦祇会跟随一楼纳得之理气属性，二楼本身之楼梯口，房门口是不会在已纳气的空间中，再自行纳出他盘的。 因为纳气过程已由地下一楼之大门在建成时完成，所以在一个空间内，不可能成立有两个不同的理气属性的。

各种取向分析

现今家居立极

由以上古代建筑，引伸到现今之房屋结构，无论它是三层之村屋，六层之洋楼，或超过十层以上的大厦。 其纳气之条件，过程及道理，都为无异。 故此，所有有形之建筑物，衹要是同一结构内的，总是由大门来纳气。 所以，以单位门来作定坐立向的方法，绝对为不正确。

单位立极

如果我们要知道在一幢大厦中的，其中一个单位之风水理气星盘，便需要首先量度这幢大厦的大门方向，从而用这度数，起出飞星盘，再以同等之角度，引入这房屋单位之立极中心点，始来相宅布局。

现今房屋建筑结构远比古时的房屋复杂，很多时候，在一些大厦式洋楼中，经常发觉不衹一个大门。 有些情况是，除了正式之大门外，平台花园亦建有便门。 另有些情况是，大门建在地面，但左右亦同时有二个不同方向之门。 更有些情况是，大门衹建在平台花园，但在平台花园下之停车场，亦有大门出入。 林林种种，不一而终。 所以要断何为正确之纳气大门，亦相当之不容易。

我们要知悉，大厦本身已然纳气，所得之卦气已成，而且亦已立极。 所以我们不要发现上述情况时，便胡乱断之为「人多出入为纳气门」，「大小门当以大为向」等谬论。 世人要知，建筑物风水纳气过程是在建成时已发生，既定之理气亦不会「人多行」，「大胜小」而改变的。 风水上之门，亦不是人们所看到的门，所为研究风水之后学，请慎而重之。 用纳气规则去断何者为门为向，千万不要每幢门都起一飞星盘，再详问房屋中发生何事来断，此种做法，实为正统玄空师傅所不耻。

乘气之门

纳得当时得令令星到门者，为乘气之门。 反之，纳得衰败之星到门者，为脱气之门。 玄空飞星重到门之星，亦即到门之卦气也。 断宅时，故以本身单位门为重，但亦不能疏忽到本身大厦大门纳得之卦气。 如单位门脱气，大厦大门亦为脱气，为凶。 单位门乘气，大厦大门脱气，亦为不甚理想。 最佳者，当然是单位门及大厦大门都同时乘气，为玄空之吉局。

选旺而居

风水上的理气是随地而行，随屋而附的。 如大厦乘气得旺，理气会由大门流入，以大厦之阳基形状，分八方而立极中央。 卦气星盘之旺气不会胡乱奔走，它是按着原本卦气星盘之方作流向。 所以玄空之选局，以大厦星盘立极后之旺方为要。 如单位坐落此方，便以此为选。 反之，如衰谢之气，即弃之不用。 不过，世事多矛盾，坐落旺方之单位，多不能开立旺门。 实为一大讽剌也。

门路气路

玄空重门路所形成的气路，得乘气之门，旺气入宅。 那是否宅旺人就旺？ 其实未必。 旺气由门入，会跟星盘立极后之旺方流奔，布局上必须顺应旺气流走之行径而造。 流行之气该逸走何宫，该冲向何宫，那便需要精心布局的配合，所谓冲起乐宫无价宝，请珍惜固有之局面，以免入宝山而空手回也。

To Determinate the orientation of a building

To determinate the sitting and facing direction of a building is a major subject. Accurate measurement of the orientation is essential for formulating a correct flying star chart for the building. To the beginners, the orientation of a building is often regarded as the direction that its entrance faces. However, the theory behind is more complex than this.

About vital breath (Qi)

Vital breath is referred to as Qi in feng shui. In ancient times, the sages believed that Qi travelled in breezes and it moved on ground. It could feel the objects it encountered. It would get attached to a house and affected the people there.

Qi travels in air, so there is variation in energy strength: being strong or weak. It creeps on ground, so it enables a house to receive Qi through the opening at its entrance. It can feel the surroundings, and landform arrangement can alter its energy. It can attach to a house and exerts its feng shui influence. It affects people. That is why people would care about it. In conclusion, Qi is the basis of feng shui.

What is a house?

A house is an enclosure that has a foundation, four walls with a door and a roof. These are the essential elements of a house. Lacking one of these, the structure will no longer be a house. For example, if the roof is absent, it is only an enclosing wall. Without the walls, it leaves behind the roof and foundation. This is only a pavilion. Only when it is a house, it can retain Qi and there is feng shui.

Sitting and facing directions

The sitting direction refers to the back of a building, and the facing direction refers to its front where the façade is situated. When there is a back, there will be a front. When there is a sitting direction, there will be a facing direction. They are 180 degrees out of phase to each other. On the 24-mountain chart, they are exactly on the opposite side of the location readings. In a real house, opposite to the front door, there may not be necessarily a solid wall. There may be a window or a back door. But this is still regarded as the back of the house.

The door is where the Qi enters a house

The Secret of Li Qi states that Qi creeps on ground. So when Qi moves near the opening, that is the door, of a newly constructed house, it will enter the house and flow along the eight directions inside. This process is known as the reception (bringing in) of vital breath. The door plays a very important role in the process.

Orientation of the door

After entering the house, the Qi will disperse along eight directions. If the roof or wall of the house is missing or defective, the bringing in of Qi will be incomplete. The orientation of the door will determine the pattern of Qi, whether it is good or bad, to be received by the house. For example, a door having an orientation of 130 degrees will receive a completely different pattern of Qi from that with an orientation at 140 degrees.

Forming a polar centre

After Qi flowing inside the house, it will gather again near the centre to form a polar centre. Originating from there, a secondary wave of Qi will flow towards the eight corners of the house again. The polar centre will stay as where it is unless there is a change in the foundation of the house in future. Now the bringing in of Qi to the house and polar centre formation is completed. Further division of compartments such as building rooms or bathroom inside the house will not alter its original Qi pattern.

Conclusion

In Xuan Kong Feng Shui, to determine the orientation includes locating the entrance that has involved in the reception of Qi, taking an accurate measurement of the facing and sitting direction and formulating a flying star chart. Based on the Xuan Kong theory, one will choose the most auspicious location and to arrange a good path for the flow of auscipious Qi. The buildings in modern cities are often surrounded by narrow streets, flyovers, electricity cables and transmission towers. So it is difficult to take an accurate measurement of the direction of the entrance of a building.

A compass is easily interfered by surrounding magnetic fields and will not be able to give an accurate measurement. If condition allows, one should take the measurement in an open space outside the building such as in a garden or an open area. It is optimal to find a spot where there is no interference from automobiles or transmission towers etc. One usually takes measurement by aligning the compass or luo pan with the facing direction of the entrance. However, we can also measure it from the sides or the back of the building and then readjust the reading by adding or subtracting 90 or 180 degrees.

A traditional Xuan Kong Feng Shui master may use other method other than compass or luo pan to ensure that the orientation of the building is accurately measured. A slight error in measurement may sometimes result in serious detrimental consequences from feng shui arrangement.
