公孙偏与内关合，列缺能消照海 。临泣外关分主客，后 申脉正相合。左针右病知高
下，以意通经广按摩。补泻迎随分逆顺，五门八法是真科。
甲己辰戌丑未十，乙庚申酉九为期。丁壬寅卯八成就，戊癸巳午七相根据。丙辛亥子亦七
数，逐日干支即得知。
甲己子午九宜用，乙庚丑未八无疑。丙辛寅申七作数，丁壬卯酉六须知。戊癸辰戌各有
五，巳亥单加四共齐。阳日除九阴除六，不及零余穴下推。
按灵龟飞腾图有二，人莫适从，今取其效验者录之耳。
\r灵龟八法之图\ph-h4.bmp\r
假如甲子日，戊辰时，就数逐日支干内。甲得十数，子得七数。又算临时支干内，戊得五数
，辰得五数，共成二十七数。此是阳日，该除二九一十八数，余有九数，离九列缺穴也。
又如乙丑日，壬午时，就算逐日支干内。乙得九数，丑得十数。又算临时支干内，壬得
六数
皆仿此。
（与前法不同）
壬甲公孙即是干，丙居艮上内关然。戊午临泣生坎水，庚属外关震相连。辛上后 装巽
卦，乙癸申脉到坤传。己土列缺南离上，丁居照海兑金全。
其法只取本时天干为例，假如甲己日戊辰时，即取戊干临泣穴，己巳时，即列缺；庚午
时，即外关。余皆仿此。
（愚谓奇经八脉之法，各有不相同。前灵龟八法，有阳九阴六、十干十变开阖之理，用之得
时，无不捷效。后飞腾八法，亦明师所授，故不敢弃，亦载于此，以示后之学人。）
Gongsun (B4) pairs with Neiguan (PC6), Lieque (LU7) can resolve Zhaohai (KI6). Qianxi (GB41) and Waiguan (TE5) serve as the principal and secondary points respectively, Houxi (SI3) and Shenmai (BL62) are properly combined. Needling the left for right-sided ailments reveals upper and lower relationships; using intention to connect meridians and extensively applying massage. Tonification and sedation follow Ying-Sui (following and opposing) principles of reverse and smooth flow; the Five Gates and Eight Methods are the true standards.
For Jia (甲) and Ji (己) days during Chen (辰), Xu (戌), Chou (Chou), and Wei (Wei) hours, use nine. For Yi (乙) and Geng (庚) days during Shen (申) and You (You) hours, take nine as the period. For Ding (丁) and Ren (Ren) days during Yin (Yin) and Mao (Mao) hours, eight is achieved. For Wu (Wu) and Gui (Gui) days during Si (Si) and Wu (Wu) hours, seven is the basis. For Bing (Bing) and Xin (Xin) days during Hai (Hai) and Zi (Zi) hours, also seven numbers apply; daily Heavenly Stems and Earthly Branches allow one to know this.
On Jia (甲) and Ji (己) days during Zi (Zi) and Wu (Wu) hours, nine should be used. On Yi (乙) and Geng (庚) days during Chou (Chou) and Wei (Wei) hours, there is no doubt it is eight. On Bing (Bing) and Xin (Xin) days during Yin (Yin) and Shen (Shen) hours, take seven. On Ding (Ding) and Ren (Ren) days during Mao (Mao) and You (You) hours, know six. On Wu (Wu) and Gui (Gui) days during Chen (Chen) and Xu (Xu) hours, each has five. On Si (Si) and Hai (Hai) hours, add four alone to complete them. For Yang days divide by nine, for Yin days divide by six; if there is a remainder, deduce the point accordingly.
There are two diagrams for Linggui Ba Fa (Spirit Turtle Eight Methods) and Feiteng Ba Fa (Flying Sparrow Eight Methods), and people do not know which to follow. Now, I record those that have proven effective.
Suppose it is the Jia Zi (甲子) day, Wu Chen (戊辰) hour. Calculate within the daily stems and branches. Jia yields ten, Zi yields seven. Then calculate within the hourly stems and branches: Wu yields five, Chen yields five, totaling twenty-seven. This is a Yang day, so divide by eighteen (two nines). The remainder is nine, corresponding to Lieque (LU7) in the Li (离) trigram.
Again, suppose it is the Yi Chou (乙丑) day, Ren Wu (壬午) hour. Calculate within the daily stems and branches. Yi yields nine, Chou yields ten. Then calculate within the hourly stems and branches: Ren yields six. All others follow this pattern.
(Different from the previous method.)
Ren (壬) and Jia (甲) correspond to Gongsun (B4); Bing (丙) resides on Gen (艮) corresponding to Neiguan (PC6). Wu (戊) and Wu (午) correspond to Qianxi (GB41) born in Kan (坎) water; Geng (庚) belongs to Waiguan (TE5) connected to Zhen (震). Xin (辛) corresponds to Houxi (SI3) in Xun (巺); Yi (乙) and Gui (Gui) correspond to Shenmai (BL62) transmitted to Kun (坤). Ji (己) earth corresponds to Lieque (LU7) on Nan Li (South Li); Ding (丁) resides on Zhaohai (KI6) completing Dui (兑) metal.
This method only takes the Heavenly Stem of the current hour as an example. Suppose it is a Jia or Ji day during Wu Chen (戊辰) hour, then take the Wu stem corresponding to Qianxi (GB42? Note: Text says Qianxi/GB41 but context implies specific mapping, usually GB41 is Qianxi. Wait, text says "Wu Gan Lin Qi Xue" - Wu corresponds to Qianxi in some systems or here specifically mapped. Actually, standard Feiteng maps Wu to Qianxi GB41. Let's stick to text: "take Wu stem Qianxi point"). If it is Ji Si (己巳) hour, take Lieque (LU7); if it is Geng Wu (庚午) hour, take Waiguan (TE5). All others follow this.
(I believe the methods of the Eight Extraordinary Meridians are all different. The former Linggui Ba Fa (Spirit Turtle Eight Methods) has the principles of Yang Nine and Yin Six, and the ten changes of opening and closing of the Ten Heavenly Stems; when applied at the appropriate time, there is no effect that is not swift. The latter Feiteng Ba Fa (Flying Sparrow Eight Methods) was also taught by enlightened masters, so I dare not discard it, and thus record it here to show future learners.)
