父母卦即運盤，在一至九運中，亦即每一元運運星入中的飛星盤。因為風水用的是時空配方位，不應混於八卦本身之陰陽，故把當運之運星入宮按元旦盤之循環順飛。

例：一運，運星一入中順飛。

地卦即山盤，亦即坐後運星入中之飛星。而順或逆飛要以坐山的運星元旦盤所屬宮位本卦山之陰陽而定，陽順飛，陰逆飛。

例：卯山酉向一運天元卦

山星八在元旦盤天元卦為陽，故順飛。

天卦即向盤，亦即向首運星入中之飛星。而順或逆飛要以向首的運星元旦盤所屬宮位本卦山之陰陽而定，陽順飛，陰逆飛。

例：卯山酉向一運天元卦

向星3在元旦盤天元卦為陰，故逆飛。

此為完整之天地父母三盤卦。

例：卯山酉向一運天元卦

註：如五星向首或坐後，因五黃在洛書盤入中宮無卦，故只需按本運盤上之地天人三卦陰陽來決定順逆飛。

命宅星盤即是天地父母三盤卦的卦盤，所謂知父母而能知天地，天一盤、地一盤，皆由父母這一盤而生，父母者，要視建樓運即天心正運入中之盤。建樓有坐向，亦即盤中父母之向、及父母之坐，此盤之運星「即父母」，當入中作順逆排，以成星盤作宅命，此之為恆古不移之理。但學者又有否疑惑，為何其挨排定要以元旦盤五入中之星曜作其軌跡？其中之陽順陰逆這不移之理，若如以陽逆陰順作挨排，又會如何？如是者又有否有違河洛之理？

天地父母三盤卦，何以用「盤」一字？盤者，可喻為一群之意也，我們看星盤說道理，勿以單宮作論，因其「一盤」之故也。於此，我們可知各星曜在星盤上，並不以個體作表徵，他們是有牽連，有聯糸性的。先賢在其著作中，亦多次對此有發表，學者可翻書細看。

星曜成盤之說既定，我們便可進一步去理解其流向的特質，其順挨時，由星曜一白起論，即由水去土、土去木、木去木、木去土、土去金、金去金、金去土、土去火，然後火去水。又若逆挨時，由星曜一白起論，即由水去火、火去土、土去金、金去金、金去土、土去木、木去木、木去土、土去水，然後水去火。

元旦盤星曜挨排之宮位，即以中、乾、兌、艮、離、坎、坤、震、巽，作其軌跡，五行則為土、金、金、土、火、水、土、木、木。若然如我所說，不一定以元旦盤為軌跡，那可否從中、巽、震、坤、坎、離、艮、兌、乾，作其軌跡，五行則為土、木、木、土、水、火、土、金、金。

有此一說，豈非打破了三元玄空歷來的學說，又或這些根本是偽法？那怕未必，如學者有此心態，便不易在一個固有的基礎上，進一步去研究更深的學理，好像水杯盛水滿了，何以再添？我可以對大家言明，你不懂其術，就祇能活在「死法」的框架之內，莫視了先賢對玄空所形容為「活潑潑」，坊間呆板之法，祗能「等運到」，猶如流八不到令星向八之位，便需多等數年，直至流八「專臨」，運勢才顯一樣，一樣的那般無奈。我所言活潑之法，即不需等專臨到來，當年即旺，旺勢跟專臨一樣，翌年再佈局再顯威，更可比專臨時為更旺，學者知否，這正是挨排、陰陽、五行及方位上，斗轉星移之功。

The Heaven-Earth-Parent Chart

(Translator’s note: This is a composite chart comprising of 3 sets of flying stars: the time-period stars, the mountain stars and the facing stars. The formulation of the star patterns are based on the time-period when the house is built, its sitting direction and facing direction respectively. By convention, the numerals for time-period stars are documented in the lower half of each grid of the magic square. The mountain stars are put at the left upper corner of the grid, while the facing stars are at the right upper corner. The distribution of these stars provides the basis for finding an auspicious location in a house.)

The Parents’ Chart is also called the Time-period Chart. Time is stratified into periods of 20 years, and is known as Period 1 through 9. Each period lasts for 20 years and it will repeat itself when it reaches the end of Period 9. In each period, the numeral of the reigning period will fill the centre of the magic square; the other stars will be allocated in successions to the other sectors according to a specific pattern as the Luo Shu Chart.

The Earth Chart is also called the Mountain Star Chart. The numeral of the time-period star at the sitting position is used to fill the centre of the magic square. The others stars will be arranged in successions into the other sectors either in ascending or descending order. The order of progression depends on the yin-yang nature of the time-period star at the sitting direction as if it is residing in the Luo Shu chart in its respective Three-Yuan (earth, heaven, man) position. If it is of yang nature, the other flying stars will be arranged in ascending order. However, if it is yin, they will proceed in descending order.

The Heaven Chart is also called the Facing Star Chart. Similarly, the numeral of the time-period star at the facing position is used to fill the centre of the magic square. Whether the other stars are arranged in ascending or descending order depends on the yin-yang nature of the Three-Yuan position of the time-period star at the facing direction as if when it is in Luo Shu chart. If it is yang, the stars will be arranged in ascending order. However, if it is yin, they will proceed in descending order.

Note: When a time-period star at the sitting direction or facing direction is 5, ‘5’ is located in the centre of the Luo Shu Chart and it does not have any directional bearing. Therefore, the order of arrangement of stars will be according to the yin-yang nature of the three-yuan position of the trigram at that sitting or facing direction.
