假如甲子日戊辰时就数逐日支于内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除有九数是离九列缺穴也
又如乙丑日壬午时就算逐日支干内乙得九数丑得十数又美临时支干内壬得六数午得九数共成
三十九数此是阴日该除五六方三十数零有四数是巽四临泣也余皆仿此

申时、巳时，从丙寅开始；乙日、庚日，从戊寅开始；丙日、辛日，从庚寅开始；丁日、壬日，从壬寅开始，依序顺推；戊日、癸日，以甲寅为定。推算时辰的五门（指灵龟八法中的九宫数理）若得相合，便是元回（指循环往复之意）。
甲日、己日，在辰、戌、丑、未四个时辰取数十；乙日、庚日，在申、酉两个时辰取数为九；丁日、壬日，在寅、卯两个时辰取数为八；戊日、癸日，在巳、亥两个时辰取数为七；根据丙日、辛日，在子、丑两个时辰也取数为七。每日的支干数理即可由此得知。
甲日、己日，在子、午两个时辰取数为九，适宜使用；乙日、庚日，在丑、未两个时辰取数为八，毫无疑问；丙日、辛日，在寅、申两个时辰取数为七；丁日、壬日，在卯、酉两个时辰取数为六，必须知晓；戊日、癸日，在辰、戌两个时辰各取数为五；巳日、亥日单独加四。将上述数字相加，阳日总数除以九，阴日总数除以六，若有余数，则对应相应的穴位下针。

假如是甲子日戊辰时，就按逐日支干在内求得：甲得1数，子得7数；又算临时支干在内：戊得5数，辰得5数。总共成27数。这是阳日，应当除以9，得18数，余数为9。余数9对应离卦，即列缺穴。
又如乙丑日壬午时，就算逐日支干在内：乙得9数，丑得10数；又算临时支干在内：壬得6数，午得9数。总共成34数。这是阴日，应当除以6，得30数，余数为4。余数4对应巽卦，即足临泣穴。其余情况都仿照此例。
壬日、申日，公孙穴位于乾宫；丙日居艮宫；戊日，临泣穴生于坎水宫；庚日属外关，连于震宫；辛日，后溪穴装于巽卦；己日、癸日，申脉传至坤宫；己土，列缺穴在南离宫上；丁日，居照海穴，兑金宫全。
此法只取本日的天干为例。假如甲日、乙日遇到戊辰时，即取戊午时的临泣穴；己巳时即取列缺穴；庚午时即取外关穴。其余皆仿照此例。
我认为奇经八脉的用法各有相同之处，前面的灵龟八法有阳九、阴六、干十变、开阖之理，用得适时，无不迅速见效。后来的飞腾八法也是明师所授，所以不敢抛弃，也记载在前面，以便展示给学习的人。

At the hours of Shen (15:00–17:00) and Si (09:00–11:00), start with Bing Yin; on Yi days and Geng days, start with Wu Yin; on Bing days and Xin days, start with Geng Yin; on Ding days and Ren days, start with Ren Yin, following sequentially; on Wu days and Gui days, fix at Jia Yin. When the Five Gates (referring to the Nine Palace numerical system in Linggui Bafa) align, it signifies a cycle (Yuanhui).
On Jia days and Ji days, the number is ten for the Chen, Xu, Chou, and Wei hours; on Yi days and Geng days, the number is nine for the Shen and You hours; on Ding days and Ren days, the number is eight for the Yin and Mao hours; on Wu days and Gui days, the number is seven for the Si and Hai hours; for Bing days and Xin days, the number is also seven for the Zi and Chou hours. The numerical values for the daily Earthly Branches and Heavenly Stems can thus be known.
On Jia days and Ji days, the number is nine for the Zi and Wu hours, which are suitable for use; on Yi days and Geng days, the number is eight for the Chou and Wei hours, without doubt; on Bing days and Xin days, the number is seven for the Yin and Shen hours; on Ding days and Ren days, the number is six for the Mao and You hours, which must be known; on Wu days and Gui days, the number is five for the Chen and Xu hours; for Si days and Hai days, add four. Sum these numbers. For Yang days, divide by nine; for Yin days, divide by six. If there is a remainder, needle the acupoint corresponding to that remainder.
[Diagram of Linggui Bafa]
For example, on the day of Jia Zi at the hour of Wu Chen: within the daily stems and branches, Jia yields 1, and Zi yields 7. Within the hourly stems and branches, Wu yields 5, and Chen yields 5. The total is 27. This is a Yang day, so divide by 9. 27 divided by 9 leaves no remainder, but traditionally in this context, if the sum is exactly divisible or based on specific calculation methods yielding a remainder of 9 (as per the text's logic "remainder is 9"), it corresponds to Li (Fire) trigram, which is Lieque (LU-7). *Note: The source text calculates 27/9=3 rem 0, but states remainder 9 corresponds to Li/Lieque. Standard Linggui Bafa usually maps remainder 9 to Li/Lieque.*
Again, for the day of Yi Chou at the hour of Ren Wu: within the daily stems and branches, Yi yields 9, and Chou yields 10. Within the hourly stems and branches, Ren yields 6, and Wu yields 9. The total is 34. This is a Yin day, so divide by 6. 34 divided by 6 leaves a remainder of 4. Remainder 4 corresponds to Xun (Wind) trigram, which is Zulinqi (GB-41). All other cases follow this pattern.
On Ren days and Shen hours, Gongsun (PC-6) is located in the Qian palace; Bing days reside in the Gen palace; on Wu days, Linqi (Zu Linqi, GB-41) arises from Kan water; Geng days belong to Waiguan (TE-5), connected to Zhen; on Xin days, Houxi (SI-3) is placed in the Xun trigram; on Ji and Gui days, Shenmai (BL-62) transmits to Kun; Ji earth, Lieque (LU-7) is in the South Li palace; Ding days reside in Zhaohai (KI-6), completing the Dui metal palace.
This method uses only the Heavenly Stem of the current day as an example. For instance, on Jia or Yi days at the hour of Wu Chen, select the hour of Wu Wu’s Zulinqi (GB-41); at Ji Si hour, select Lieque (LU-7); at Geng Wu hour, select Waiguan (TE-5). All others follow this pattern.
I believe the methods of the Eight Extraordinary Vessels share common principles. The aforementioned Linggui Bafa involves the principles of Yang Nine, Yin Six, Stem Ten Changes, and Opening/Closing. When applied at the appropriate time, it yields swift effects. The later Feiteng Bafa was also taught by enlightened masters, so I dare not discard it, and have recorded it previously for the benefit of learners.
