When looking at Feng Shui, when should we use the innate hexagram numbers, when should we use the acquired hexagram numbers, and when should we use the river map numbers.
The hexagram numbers are all innate numbers, but the acquired numbers are regarded as Luoshu palace numbers. This is a different usage.
If divination uses innate numbers, start using hexagrams.
However, in Feng Shui, the nine palaces in Luoshu are called Li Gong, not Li Gua. However, there is a school that uses the Book of Changes to discuss Yang Zhai and the innate hexagram positions to discuss the acquired palace positions, so there will be innate and acquired The difference. For example, if the palace in the day after tomorrow is south, the number of the nine palaces in Tao Luo Shu is "nine", but the palace position in Luo Shu is "southern for time" and the innate is "qian", so the number is also "nine". As the saying goes, "the sky is south and the earth is north", this is the direction of the innate Bagua Tao Luoshu, so many Feng Shui problems are caused by not understanding the application of the first and the day after tomorrow, and they are stuck here!
But what about Hetu? It is bounded by four directions, with one in the north, two in the south, three in the east, four in the west, and five in the west as the center. This is the number of births; plus the number of five is added to form the final number. Six in the north, seven in the south, eight in the east, nine in the west, and ten are in the center. central.
Using the concept of "Heaven, South and Earth", apply Yin and Yang, the sky is Yang and the earth is Yin. The question you asked (the numbers in the river map are 2 and 7) is that "the sky creates water, and the earth creates 60% of it; the earth creates fire, and the sky creates 70% of it." The direction is south, and it is also the palace of Luoshu, but it cannot be called it. Li Gong or Li Gua.
The key point is your question: (Which number is accurate?) This question should be where you use it. If you want to use it for divination, use 3. If you want to use it for Feng Shui, it can be very flexible. The so-called nature is the body, and the day after tomorrow is the use. We also need to consider the use of ventilation first and the day after tomorrow. It is not a simple explanation.
Just like when using the Qi Men Dun Jia Bu Feng Shui Formation, the numbers used can all be used flexibly, and even the different directions of the first and the day after tomorrow can be used to promote officialdom, wealth, heirs, marriage, etc... The uses are endless!
Personally, I published a book "Digital Code" in Taiwan using Dongfang Hetu Luoshu's advanced and acquired numbers. I have unique experience, so I share it!
