This is the layer structure of the Taiyi divination board, indicating that the entire board is divided into ten layers from the center outward. When reading the board, one should examine it layer by layer from the inside out. The very center is the Central Palace, which corresponds to the Xuanshi Palace where the Five Blessings reside. Among the ten Heavenly Stems, the stems Wu and Ji belong to the earth element. The first layer arranges the sixteen intermediately positioned spirits, which are derived from the twelve Earthly Branches combined with the four cardinal directions Qian, Kun, Gen, and Xun. The second layer arranges the eight palaces, which are the first, second, third, fourth, sixth, seventh, eighth, and ninth palaces, excluding the Central Palace, and are used for determining the affairs of the time. The third layer arranges the sixteen spirits. The fourth layer arranges the eight gates, nine stars, and the spirits of the Six Yi and Six Bing associated with the nine palaces. The fifth layer marks the positions governed by each of the ten Heavenly Stems. The sixth layer marks the boundaries of the Five Blessings and the three foundations: the Sovereign's foundation, the Minister's foundation, and the People's foundation. The seventh layer marks the boundaries of the four spirits, Tianyi, Diyi, and Zhizhu. The eighth layer arranges the twenty-eight star mansions. The ninth layer records the affairs governed by each of the twenty-eight star mansions. The tenth layer marks the boundaries of the nine states and the twelve countries. When setting up a divination, first determine the palace where Taiyi resides, then proceed layer by layer according to these ten layers, thereby corresponding the spirits, star mansions, and terrestrial states and countries one by one.

This is a recorded layout from the actual observation in the fourth year of the Dinhai era (the fifteenth year of the Wanli period). It can serve as a model for casting a divination chart. In this year, the great touring Taiyi entered the Xun palace, which is the ninth palace. The small touring Taiyi was in Yang Dun in the ninth palace and Yin Dun in the first palace. The six palaces of the straight affairs and the Du gate of the straight affairs have been stationed since the Jiazi year of the Jiajing period, and have now been in place for twenty-four years. The positions of the three bases are as follows: the king's base has been stationed in the亥 position since the Jia Shen year of the Wanli period, and has now been in place for four years; the minister's base has been stationed in the酉 position since the Dinhai year of the Wanli period, and has now been in place for one year; the people's base has been stationed in the未 position in the Dinhai year of the Wanli period. The five blessings have been stationed in the Huangmi palace since the Jimao year of the Wanli period, and have now been in place for nine years. The four spirits have been stationed in the巳 position since the Yiyou year of the Wanli period, and have now completed their term by the Dinhai year; the heavenly yi has been stationed in the戌 position since the Yiyou year of the Wanli period, and has now completed its term by the Dinhai year; the earthly yi has been stationed in the丑 position since the Yiyou year of the Wanli period, and has now completed its term by the Dinhai year; the straight symbol has been stationed in the酉 position since the Yiyou year of the Wanli period, and has now completed its term by the Dinhai year. Any mention of 'entering a certain position for a certain number of years' refers to the deity having been stationed in that position since that year, and moving to the next position once the number of years has been fulfilled.

Following this are the positions of each god in both the Yang Dun and Yin Dun charts for the same year, which can be cross-referenced with the previous records of the year. Wen Chang: in Yang Dun it is in the辰 (Chen) position, and in Yin Dun it is in the戌 (Xu) position. The main general: in Yang Dun it is in the first palace, and in Yin Dun also in the first palace. The deputy general: in Yang Dun it is in the third palace, and in Yin Dun also in the third palace. The initial strike: in both Yang and Yin Dun it is in the寅 (Yin) position. The guest general: in Yang Dun it is blocked by the Du gate and cannot exit the Central Palace, while in Yin Dun it is in the ninth palace. The guest deputy general: in Yang Dun it is also blocked, while in Yin Dun it is in the seventh palace. The intelligence god: in Yang Dun it is in the fourth position, and in Yin Dun in the sixth. The general for setting the plan: in Yang Dun it is in the丑 (Chou) position, and in Yin Dun in the未 (Wei) position. The general for the plan: in Yang Dun it is in the ninth palace, and in Yin Dun in the third palace. The deputy general for the plan: in Yang Dun it is in the ninth palace, and in Yin Dun in the seventh palace. By filling in this column of data into the ten-layer chart, the complete annual military calculation chart for the Wanli Dinghai year is formed.

十六宮間之神 子地主 丑陽德 艮和德 寅呂申 卯高叢 辰太陽 巽太炅 巳大神 午大威 未天道 坤大武 申武德 酉太簇 戌陰主 亥大義

Here are the names of the "Sixteen Palace Deities" along with their corresponding directions. The term "Palace Deities" refers to the twelve Earthly Branches combined with the four cardinal trigrams: Qian (Heaven), Kun (Earth), Gen (Mountain), and Xun (Wind), making a total of sixteen positions. Each position has a specific deity name, and on the Taiyi disk, when a general is said to "be stationed at a certain position," it refers to these names. The correspondences are as follows: the Zi position corresponds to Di Zhu (Earth Lord), the Chou position to Yang De (Yang Virtue), the Gen position to He De (Harmony Virtue), the Yin position to Lv Shen (Lv Shen), the Mao position to Gao Cong (High Thicket), the Chen position to Tai Yang (Great Sun), the Xun position to Tai Jing (Great Radiance), the Si position to Da Shen (Great God), the Wu position to Da Wei (Great Authority), the Wei position to Tian Dao (Heavenly Way), the Kun position to Da Wu (Great Wu), the Shen position to Wu De (Martial Virtue), the You position to Tai Cu (Tai Cu), the Xu position to Yin Zhu (Yin Lord), and the Hai position to Da Yi (Great Righteousness). These sixteen names appear repeatedly in the various sections of the text. For example, "Tian Mu Wu De" means the Tian Mu (Heavenly Eye) is located at the Shen position, and "Shi Ji Jiang Da Yi" means the Shi Ji (Initial Strike) is located at the Hai position. By referring to these positions, the deities and generals can be identified with specific directions.

太乙諸星 文昌 主大將 主參將 始擊 客大將 客參將 計神 定計將 計參將 五福 大遊 君基 臣基 民基 四神 天乙 地乙 直符 飛符

Here are the various stars to be observed on the Taiyi board. According to the order of selection when making a divination, first look at Wen Chang, then the main general, the deputy general, the initial strike, the enemy's main general, the enemy's deputy general, and the strategist. Then look at the general determined by the strategist's calculation and the deputy strategist derived from it. The above are the commonly used stars that must be arranged in every case. In addition, there is another group of stars that change over a longer period and shift according to the year: Wu Fu, Da You, Jun Ji, Chen Ji, and Min Ji, the three bases, as well as Si Shen, Tian Yi, Di Yi, Zhi Fu, and Fei Fu. The first group governs the victory and defeat of the host and guest within a single case, while the second group governs the long-term fortune and misfortune of the country and harvests. Only by examining both groups together can the Taiyi board be fully interpreted.

年局（以百十零為主不除，滿千後方除之）置上元甲子至萬曆戊子，積得一千零一十五萬五千五百零五算，截得祖數一百九十三萬八千一百四十五算，以大周法三百六十除之，餘二百六十五算，又除四紀二百四十，餘二十五策。一甲子位，十一甲戌位，二十一甲申位，二十二乙酉，二十三丙戌，二十四丁亥，二十五戊子，仍還二百六十五策，以元法除之，甲子元除去七十二，丙子元除去七十二，戊子元除去七十二止，餘四十九算，則知戊子歲即庚子元四十九局也。

To calculate the year's stem and branch, first accumulate the years. Keep the hundreds, tens, and units digits as they are, and only start dividing when the total reaches the thousands place. The specific method is as follows: starting from the beginning of the cycle, the Jiazi year, and accumulating up to the Wanzhi Wuzi year, the total is one million and fifteen thousand five hundred and five units. From this, take the "ancestral number" of one hundred ninety-three thousand eight hundred and forty-five units. First, divide this ancestral number by the "Great Cycle Method" of three hundred sixty. If it does not divide evenly, the remainder is two hundred and sixty-five units. Then subtract four cycles of two hundred and forty units, leaving twenty-five units. Then proceed according to the sequence of the Jiazi decade: the first is the Jiazi position, the eleventh is the Jiaxu position, the twenty-first is the Jiashen position, the twenty-second is the Yiyou position, the twenty-third is the Bingxu position, the twenty-fourth is the Dinghai position, and the twenty-fifth is the Wuzi position—thus confirming the stem and branch of the year. Then take the original number of two hundred and sixty-five units back, and divide it using the "Original Method": first subtract the seventy-two units of the Jiazi original cycle, then subtract the seventy-two units of the Bingzi original cycle, then subtract the seventy-two units of the Wuzi original cycle, and stop here. The remainder is forty-nine units. Thus, the year Wanzhi Wuzi is the forty-ninth unit of the Gengzi original cycle. The entire process is: accumulate years → take the ancestral number → use the Great Cycle Method and four cycles to determine the stem and branch → use the Original Method to determine which original cycle and which unit it is.

月局（起算即加天正、地正二算）甲子、甲午，一紀；己亥、己巳，二紀；甲戌、甲辰，三紀；己酉、己卯四紀；甲申、甲寅，五紀；己未、己卯，六紀。甲子、甲午六年，甲子元七十二局；庚子、庚午六年，丙子元七十二局；丙子、丙午六年，戊子元七十二局；壬子、壬午六年，庚子元七十二局；戊子、戊午六年，壬子元七十二局。

To determine the monthly division, first add the two calculations of "Heavenly Correct" and "Earthly Correct" before proceeding. The pairing of the six periods is as follows: Jiazi and Jiawu form one period, Jihai and Jisi form the second, Jiaxu and Jiachen form the third, Jiyou and Jimao form the fourth, Jiashen and Jiayin form the fifth, and Jiwei and Jimao form the sixth. The pairing of the five elements with the years is as follows: the six years starting from Jiazi or Jiawu use the seventy-two divisions of the Jiazi element; the six years starting from Gengzi or Gengwu use the seventy-two divisions of the Bingzi element; the six years starting from Bingzi or Bingwu use the seventy-two divisions of the Wuzi element; the six years starting from Renzi or Renwu use the seventy-two divisions of the Gengzi element; and the six years starting from Wuzi or Wuwu use the seventy-two divisions of the Renzi element. Each element period includes seventy-two divisions. First determine which element period the year belongs to, then count the number of divisions corresponding to the required month within that element period to find the monthly division.

日局弘治元年戊申歲，截算得祖數二百一十三策，用退而成，逐年一進一退，逢閏重退，進用已往二十四月之數，退用已往小盡之數。假如今年元旦日辰退居去年元旦之後，則用退，明年元旦日辰進居今年元旦之前，則用進，退不過五六，進不過二十四，一定之數也，先以紀法求日，次以元法取局，與歲計皆同。

To calculate the day structure, we take the year of Hongzhi 1, Wushen, as the starting point. By calculation, we arrive at a total of 213 strategies, which is obtained by using the method of 'retreating'. Subsequently, each year is adjusted by one step forward and one step backward, and in leap years, an extra retreat is made. The term 'forward' refers to the number of months that have already passed, specifically twenty-four months. The term 'backward' refers to the number of small months (each small month has twenty-nine days) that have already passed. To determine whether to use forward or backward, we look at the day branch on New Year's Day. If the day branch of this year's New Year has retreated to after last year's New Year, then we use the method of retreating. If the day branch of next year's New Year has advanced to before this year's New Year, then we use the method of advancing. The maximum number of retreats is no more than five or six, and the maximum number of advances is no more than twenty-four, these are fixed limits. Once the number is determined, we first use the jì method to find the day branch, then use the yuan method to determine the structure number. The steps are the same as those used in calculating the annual count.

時局與月局同，但不加天地二算，冬至後用陽局，夏至後用陰局。

To determine the time situation, the method is the same as for the monthly situation, except that when starting the calculation, there is no need to add the two calculations of Tianzheng and Di Zheng. As for whether to use the Yang Dun or Yin Dun, it is determined by the solstices: after the winter solstice, the Yang Dun of seventy-two situations is used, and after the summer solstice, the Yin Dun of seventy-two situations is used. This is because after the winter solstice, the Yang begins to grow and the qi flows in a forward direction, while after the summer solstice, the Yin begins to grow and the qi flows in a reverse direction, so the direction of Taiyi's palace also changes accordingly.

太乙（陽遁起一宮，順行至九宮；陰遁起九宮，逆行至一宮，因所求局未滿二十四，以二十四除之，不盡者，皆以一宮三數輪之，即知太乙所在歲計，萬曆戊子陽遁一宮，理天，陰遁九宮）

The method of calculating Taiyi: In Yang Dun, Taiyi starts from the first palace and proceeds in a clockwise direction to the ninth palace; in Yin Dun, Taiyi starts from the ninth palace and moves counterclockwise to the first palace. Since the required structure number is often less than twenty-four, divide twenty-four into it, take the remainder, and then count through each palace according to the rule that each palace corresponds to three years. This determines which palace Taiyi falls into, which is the annual Taiyi. For example, in the Wuzi year of the Wanli era, in Yang Dun, Taiyi is in the first palace, which is the year of "Li Tian"; in Yin Dun, Taiyi is in the ninth palace.

太乙者，天地之尊神，在北辰前，正當勾陳口中，天乙紫微垣宮門右星南。主使十六神而知風雨、水旱、兵革、飢饉、疾病、災害，國主興亡，曆數脩短，遊行九宮而歷八卦，自太始初分，從其一，一生二，二生三，三即天地人也，日月星也，乙丙丁也，上中下也，以三乘三為九，以三乘九為二十七，故太乙行宮每位住三年，一年治天，整五星失度，日月薄蝕，妖慧光怪之變；二年治地，整山崩水陷，水決河翻，蝗蟲、土工之變；三年治人，整君臣父子、口舌妖言、疾病、飢饉、生靈流亡之變。蓋三年一宮，二十七年一周天，但不遊中宮，寄在七宮，故二十四年一周天耳。

Taiyi is the most exalted deity in the universe, located before Beichen, right in front of the mouth of Gou Chen star, to the south of the right star of the Tianyi Ziwēi垣 palace gate. It commands sixteen deities and thus can foresee rain and wind, drought and flood, war and peace, famine and disease, calamity and disaster, and can know the rise and fall of kings and the length of a country's destiny. It travels through the nine palaces and traverses the eight trigrams. Starting from the initial division of Tai Shi Qi: first there is one, one gives rise to two, two gives rise to three; this three represents heaven, earth, and humanity, the sun, moon, and stars, the Yi, Bing, and Ding, the upper, middle, and lower. Three multiplied by three gives nine, three multiplied by nine gives twenty-seven, so Taiyi stays in each palace for three years: the first year governs heaven, rectifying abnormal movements of the five stars, eclipses of the sun and moon, and strange celestial phenomena; the second year governs earth, rectifying mountain collapses and land subsidence, river and river breaches flooding, locust plagues, and construction projects; the third year governs humanity, rectifying disorder among rulers and subjects, false words and rumors, diseases and famine, and the migration of the people. One palace per three years, twenty-seven years should complete a full cycle around the heavens; but Taiyi does not travel through the central palace, and the number of the central palace is assigned to the seventh palace, so in reality, it takes twenty-four years to complete a full cycle.

置上元甲子至所求積年，以太乙行度二百八十八去之，不盡以二十四去之，又不盡者，為入宮年數，遇掩、擊、格、迫在陽絕之地與曆數同者，其災甚也，其有不發者，不在陽九、百六下元故災漸傍，若當陽九、百六而合下元甲子，即兵革攻伐，篡弒襲戮之災，若在歷運太陽、陰主下，入大遊卦文者，必有改易也。

The method of calculating the year in which Taiyi enters the palace is as follows: starting from the upper beginning Jiazi, count the accumulated years up to the desired year. First divide this number by 288, which is the movement of Taiyi. If there is a remainder, divide it by 24. The final remainder is the year in which Taiyi enters the palace. If this year coincides with theInauspicious Pattern of concealment, attack, obstruction, or constraint, and it falls in the "Yang绝" position, and aligns with the calendar numbers, the calamity will be particularly severe. However, there are cases where theInauspicious Pattern does not manifest, because they have not encountered the two critical periods of "Yang Jiú" and "Bai Liu", and they are not in the lower beginning, so the calamity only gradually dissipates on the sides. If it is exactly the years of Yang Jiú and Bai Liu, and coincides with the lower beginning Jiazi, there will be great disasters such as warfare, usurpation of the throne, assassination of the sovereign, and sudden attacks and massacres. If it falls under the Sun or the Yin ruler of the calendar and enters the hexagram text of the Great Tour hexagram, then the dynasty's policies will certainly change.

一宮在乾，主冀州、幷州，若文昌關囚，是謂相佐迫協君父之象；二宮在離，主荊州、豫州，太乙臨之，象人君居明堂誅將相、去奸邪；三宮在艮，主青州，主后妃，主閽寺，始擊臨之，嬖寵進中宮，兵起；四宮在震，主徐州，始擊臨之，西戎兵侵；六宮在兌，主雍州，客大將臨之，南楚侵（或曰擊臨南楚侵）；七宮在坤，主樑州、益州，主大將臨之，梁益兵起；八宮在坎，主袞州，太乙臨之，應紫微宮，嚮明而治，若二目曰對，大臣伏誅；九宮在巽，主揚州，客大將臨之，北狄來侵，巳上九宮，其在關囚掩迫格擊提挾固杜之年，驗之必矣，若三才算和，而無囚迫，所主為輕耳。

Each of the nine palaces has its own trigram position and corresponds to a region on the ground. When divining state affairs, one must determine the outcome based on the palace. The first palace is Qian (Heaven), governing Ji Zhou and Bing Zhou; if Wen Chang is in this palace and is blocked or imprisoned, it signifies that the ministers are forcing the sovereign and his father. The second palace is Li (Fire), governing Jing Zhou and Yu Zhou; if Taiyi is in this palace, it symbolizes the sovereign sitting in the Bright Hall to execute ministers and eliminate villains. The third palace is Gen (Mountain), governing Qing Zhou, and also relates to the empress and eunuchs; if the initial strike is in this palace, it indicates that favored individuals enter the Central Palace and military conflict is about to arise. The fourth palace is Zhen (Thunder), governing Xu Zhou; if the initial strike is in this palace, it indicates an attack from the western nomads. The sixth palace is Dui (Lake), governing Yong Zhou; if the guest general is in this palace, it signifies an invasion from the southern Chu region (another interpretation says that if the initial strike is in this palace, then southern Chu will invade). The seventh palace is Kun (Earth), governing Liang Zhou and Yi Zhou; if the main general is in this palace, it indicates military action in the Liang and Yi regions. The eighth palace is Kan (Water), governing Gun Zhou; if Taiyi is in this palace, it corresponds to the Purple Micro Palace, indicating the sovereign governing with clarity and openness. If the main and guest generals' positions conflict and form a 'pair,' then a high-ranking minister will be executed. The ninth palace is Xun (Wind), governing Yang Zhou; if the guest general is in this palace, it indicates an invasion from the northern Di people. Among these nine palaces, whenever the years of being blocked, imprisoned, covered, forced, restricted, struck, lifted, seized, fixed, or blocked occur, the predictions will definitely come true on time. If the calculation of the three heavens is harmonious and there is no blocking or forcing, the misfortune it indicates will be less severe.

八三四九為陽宮，二七六一為陰宮，歲計太乙與文昌、始擊、主客大小將在一宮，則為陽絕，在九宮則為絕陰，在四六則為絕氣，在二八則為易氣，遇掩迫囚擊格挾固杜之年，而有大凶交，餘（九宮大凶，有凶交）更會卦運，內外極爻，除舊更新，禍患深重（一九宮最重，餘稍輕），三才算和，為災尚輕。凡舉百事，慎而勿用，四計皆同。

The nine palaces are divided into two groups of yin and yang: eight, three, four, and nine are yang palaces, while two, seven, six, and one are yin palaces. In terms of the year, if Taiyi and Wen Chang, Shi Ji, Zhu Ke, and the major and minor generals all fall into the same palace, it is called "Yang Jie." If they all fall into the ninth palace, it is called "Jue Yin." If they fall into the fourth or sixth palace, it is called "Jue Qi." If they fall into the second or eighth palace, it is called "Yi Qi." Whenever there are years marked by concealment, pressure, captivity, attack, blocking, restraint, firmness, or obstruction, there will be a great凶 meeting (especially in the ninth palace, which is extremely凶 and will have a凶 meeting). If this coincides with the shifting of the trigrams and the extreme lines of the inner and outer trigrams are in charge, it indicates a renewal, but the calamity will be particularly severe (with the first and ninth palace being the worst, and the rest somewhat lighter). Only when the three elements are in harmony will the calamity be somewhat lighter. In such years, one should be cautious in doing anything and preferably avoid action altogether; the interpretation for the year, month, day, and hour is the same.

文昌（陽遁起申，順行，乾、坤重留一算；陰遁起寅，順行，艮、巽重留一算，因所求局數，以十八除之，命起寅、申，即知文昌陽遁在巽，陰遁在乾）

The method of calculating the position of Wen Chang: For Yang Dun, start from the Shen position and proceed in order, when reaching the Qian and Kun trigrams, leave an extra count. For Yin Dun, start from the Yin position and proceed in order, when reaching the Gen and Xun trigrams, leave an extra count. Use the required structure number divided by eighteen, take the remainder. For Yang Dun, count from Shen, and for Yin Dun, count from Yin. This will determine the position of Wen Chang. For example, in the Wuzi year of Wanli, Wen Chang is in Xun for Yang Dun and in Qian for Yin Dun.

文昌六星在北斗魁前天乙之府，乃為天乙之目，故曰天目，屬土、主人，為中宮鎮星之精，屬土，旺於四季，能知天地間無窮之事，為太乙之輔象，輔相掌斷天下吉凶，能預知也，皆徙算於太乙宮而止，不可同宮，同宮囚，不利主人，若在陽絕之地而算數虧者，君之災也；若在太乙前宮，名外宮迫，主臣下有外謀；在太乙後一宮，名內宮迫，主下有陰謀，或後宮女子之私也；若與太乙相沖者，名曰對，對者，臣下失禮，王綱格易也，有僭拒沉機之謂也，對者，災輕，若凶門加而庚辛臨之，又得天芮、天禽、天英、天理、天蓬加之，必有臣下謀上也；

The Wen Chang star is originally the six stars in front of the Tian Yi palace in the Big Dipper's handle, and is regarded as the eyes of Tian Yi. Therefore, in the Taiyi system, it is also called the "Heavenly Eye." It belongs to the Earth element and governs human affairs. It is the essence of the Central Palace planet (the planet of Earth), and is strong in the months of the four seasons. It can know infinite matters in the universe and represents the auxiliary and supportive aspect of Taiyi, helping Taiyi to judge the fortune and misfortune of the world and foresee events. When calculating, the numbers for each general are counted until they reach the Taiyi palace. Wen Chang should not be in the same palace as Taiyi; if they are in the same palace, it is called "qu" which is unfavorable for the ruler. If Wen Chang is in a yang dead position and the calculation is lacking, it indicates that the king will suffer misfortune. If Wen Chang is in the palace before Taiyi, it is called "external palace pressure," indicating that ministers may plot outside. If Wen Chang is in the palace after Taiyi, it is called "internal palace pressure," indicating conspiracy below or private affairs among the queen's women. If Wen Chang is directly opposite Taiyi, it is called "opposition," which means ministers lose decorum, the laws and regulations are altered, implying overstepping and resistance, and hidden schemes. If only there is opposition, the disaster is not severe. However, if it is combined with evil gates, and the stars Geng and Xin are present, along with the evil stars Tian Rui, Tian Qin, Tian Ying, Tian Li, and Tian Peng, then there will certainly be plots by ministers against the ruler.

若與始擊同宮，名曰二目關，則旺相者勝，如在一三七八宮者，主人勝，如在二六四九宮者，客勝。太乙在一宮，天目九宮對者，有災相輔當之；太乙在二宮，天目在八宮，有變君父之災也；太乙在六宮，天目在四宮，有支宰輔大將之災也。曰者天目在旺宮，君父之災也；太乙乘旺宮，主君誅臣下也，皆以五行旺相推之，此為天月之變也。

When the Wen Chang star is in the same palace as the initial strike, it is called "two eyes in the same palace." At this time, one should look at which side is in a prosperous and strong condition: if Wen Chang is in the first, third, seventh, or eighth palace, the ruler will win; if it is in the second, sixth, fourth, or ninth palace, the guest side will win. Then examine the specific conflicting situations: if Taiyi is in the first palace and Tianmu is in the ninth palace, facing each other, there will be disaster, which will be borne by the minister; if Taiyi is in the second palace and Tianmu is in the eighth palace, there will be disaster involving the ruler and father; if Taiyi is in the sixth palace and Tianmu is in the fourth palace, the main general will be in trouble. If Tianmu falls in a palace of prosperous energy, it indicates disaster for the ruler and father; if Taiyi itself is in a palace of prosperous energy, it indicates the ruler will punish the ministers. All of these should be judged according to the prosperity, strength, weakness, and confinement of the Five Phases. This is how Tianmu indicates changes and variations.
