Calculations of Palace Elemental Nature using 纳音五行 and the Derivations of Star Characteristics

What I am presenting here is a simple but very under-represented concept in Zi Wei Dou Shu, which is the elemental interactions within the Palaces that confer the nature of the Stars.  In every of the 12 Palaces, there is an elemental dynamic known as 宮氣 (Gong Chi). The elemental interplay will give an indication on the 星性 (Xing Xin; Nature of the Star), which essentially gives the true characteristic of the Star. This is notwithstanding the fact that the Star was already influenced by their Magnitude. These calculations are not indicative of the order of Magnitude of the Stars in the respective Palaces, rather it shows how what nature of the Characteristics will be evident.

For example 武曲 Star is 廟 (Blazing) in the highest order of Magnitude in the 甲戌 Palace. This goes to show that 武曲 is able to maximize its potential. However the 甲戌 Palace is of elemental Fire, which can destroy the 武曲 elemental Gold, henceforth the true star characteristic actually shows its negative side, which in the case here is that of inflexibility, passive, stubborn nature. The two aspects show that 武曲 in this case is STRONGLY STUBBORN.

The elemental dynamic within the palace is first derived from the sexagenary cycles based on the 10 天干 (Tian Gan, Heavenly Stems) and 12 地支 (Di Zhi, Earthly Branches) which are indicated by the birth date/time of the native. Each of the palace has its own combinations of Tian Gan/Di Zhi and each of this combination will confer an elemental nature. One way to derive their elemental nature is to utilize the 纳音五行 (Na Ying Wu Xing), elemental harmonic hymn but simplified in the layout below. Every Tian Gan, Di Zhi and Na Ying Elements are represented with a number that serve as basic mathematical equations that derive the nature of the Element.

天干 (Tian Gan): 甲乙-1,丙丁-2,戊己-3,庚辛-4,壬癸-5
地支 (Di Zhi): 子丑午未-1,寅卯申酉-2,辰巳戍亥-3
纳音五行 (Na Ying Wu Xing): 1 木,2 金,3 水,4 火,5 土
Example A 丙子: The Na Ying Elemental Calculation will be 丙 2 + 子 1= 3 水 (Water).
Example B 庚申: The Na Ying Elemental Calculation will be 庚 4 + 申 2= 6; 6-5= 1 木 (Wood) . When a derived sum is larger than that of 5, we will take the total and minus away 5, henceforth the Na Ying number is 1, corresponding to Wood.

Once the Element of the Palace is determined, we will see its effect on the Stars. The concepts of 相生 Mutual Growth and 相剋 Mutual Destruction are important in the elemental interplay that determines the nature of the Stars. First thing we need to establish is the elemental nature of the Star.

For example, 天梁 is of the Yang Earth Element. If it falls within the 戊午 Palace, it will show its best characteristics like empathy, altruism etc. The Element of the 戊午 Palace is Fire. Fire grows Earth. *UPDATE There is an error in an earlier version here which is now corrected: If it falls within the wood palaces like 辛卯, it will show its worst characteristics like overtly emotional, too sensitive, etc. Wood obliterate Earth. There also exists a neutral point where both the good and bad characters are balanced. In 乙午 Palace, the Element is that of Metal. Here the growth is reversed, Earth grows Metal. This is still considered an indication of more positive characteristics, although it tends to fall back to the neutrality of the character due to the reverse of growth.
