父母卦即运盘，在一至九运中，亦即每一元运运星入中的飞星盘。 因为风水用的是时空配方位，不应混于八卦本身之阴阳，故把当运之运星入宫按元旦盘之循环顺飞。

例：一运，运星一入中顺飞。

地卦即山盘，亦即坐后运星入中之飞星。 而顺或逆飞要以坐山的运星元旦盘所属宫位本卦山之阴阳而定，阳顺飞，阴逆飞。

例：卯山酉向一运天元卦

山星八在元旦盘天元卦为阳，故顺飞。

天卦即向盘，亦即向首运星入中之飞星。 而顺或逆飞要以向首的运星元旦盘所属宫位本卦山之阴阳而定，阳顺飞，阴逆飞。

例：卯山酉向一运天元卦

向星3在元旦盘天元卦为阴，故逆飞。

此为完整之天地父母三盘卦。

例：卯山酉向一运天元卦

注：如五星向首或坐后，因五黄在洛书盘入中宫无卦，故只需按本运盘上之地天人三卦阴阳来决定顺逆飞。

命宅星盘即是天地父母三盘卦的卦盘，所谓知父母而能知天地，天一盘、地一盘，皆由父母这一盘而生，父母者，要视建楼运即天心正运入中之盘。 建楼有坐向，亦即盘中父母之向、及父母之坐，此盘之运星「即父母」，当入中作顺逆排，以成星盘作宅命，此之为恒古不移之理。 但学者又有否疑惑，为何其挨排定要以元旦盘五入中之星曜作其轨迹？ 其中之阳顺阴逆这不移之理，若如以阳逆阴顺作挨排，又会如何？ 如是者又有否有违河洛之理？

天地父母三盘卦 何以用“盘”一字？ 盘者，可喻为一群之意也，我们看星盘说道理，勿以单宫作论，因其「一盘」之故也。 于此，我们可知各星曜在星盘上，并不以个体作表征，他们是有牵连，有联糸性的。 先贤在其著作中，亦多次对此有发表，学者可翻书细看。

星曜成盘之说既定，我们便可进一步去理解其流向的特质，其顺挨时，由星曜一白起论，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，然后火去水。 又若逆挨时，由星曜一白起论，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，然后水去火。

元旦盘星曜挨排之宫位，即以中、乾、兑、艮、离、坎、坤、震、巽，作其轨迹，五行则为土、金、金、土、火、水、土、木、木。 若然如我所说，不一定以元旦盘为轨迹，那可否从中、巽、震、坤、坎、离、艮、兑、乾，作其轨迹，五行则为土、木、木、土、水、火、土、金、金。

有此一说，岂非打破了三元玄空历来的学说，又或这些根本是伪法？ 那怕未必，如学者有此心态，便不易在一个固有的基础上，进一步去研究更深的学理，好像水杯盛水满了，何以再添？ 我可以对大家言明，你不懂其术，就祇能活在「死法」的框架之内，莫视了先贤对玄空所形容为「活泼泼」，坊间呆板之法，祗能「等运到」，犹如流八不到令星向八之位，便需多等数年，直至流八「专临」，运势才显一样，一样的那般无奈。 我所言活泼之法，即不需等专临到来，当年即旺，旺势跟专临一样，翌年再布局再显威，更可比专临时为更旺，学者知否，这正是挨排、阴阳、五行及方位上，斗转星移之功。

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.
