女子原来命有三，紫白黄光不似男。
少上衰中成在下，关头一路要深谙。
女命有三，紫、白、黄是也。光之黄者，丹田生丹之处也。白者，胎元结胎之地也。紫者，血光生血之
海也。其在上者为阳穴，在中者为黄房，在下者为丹田。
当其少也，天癸满一斤之数，丹田真元之气足，上升血元生血，阳极变阴，化浊经而流行于外，故少

及其衰也，天癸耗尽，气不能上升以生血，而腰干血涸则经无矣，故衰则从中。若欲修成干体，须从
下田运上阳穴，神火薰蒸，使经变黄，黄变白，白化无，形自隐矣。故曰成则从下，与男子不同。不识此

气穴无它即乳房，休将脐下妄猜量。
人如不识阴生处，安使毒龙自伏藏。
气穴，即血元也，即乳房也，在中一寸三分，非两乳也。男命在丹田，故以下田为气穴；女命在乳房，

每到花开对月时，羝羊正欲触藩篱。
劝君信至休迟误，莫待赤龙出水湄。
《先天玄微》曰∶女子未生之前，父母媾精之际，父精先至，母血后行，血裹精而成女形。女子

女子原本有三条生命路径，其紫、白、黄三种光色与男子不同。
少时在上，衰时在中，成就在下，这关键的转折点必须深刻领悟。
女子的三条生命路径，指的是紫、白、黄三色。黄色的光，是丹田产生丹药的地方。白色的光，是胎元凝结成胎的地方。紫色的光，是血海生成血液的地方。位于上方的称为阳穴，位于中间的称为黄房，位于下方的称为丹田。
当女子年少时，天癸（月经）满一斤之数，丹田的真元之气充足，上升的血元能够生血，阳极变阴，将浊经转化为流行于体外的经血，所以年少时是从上部开始变化。
等到女子衰老时，天癸耗尽，气不能上升以生血，腰部干枯、血液枯竭，月经也就停止了，所以衰老时是从中部状态维持。如果想要修炼成干体（无月经之体），必须从下丹田运送到上部的阳穴，用神火熏蒸，使经血变为黄色，黄色变为白色，白色化为虚无，形体自然隐没。所以说成就时是从下部开始，这与男子不同。如果不识得这个关键关口，丹药就无法炼成。
气穴没有别的，就是乳房，不要错误地猜测在脐下。
人如果不知道阴气产生的地方，怎么能让毒龙（指月经）自然伏藏？
气穴，也就是血元，即乳房，位于中一寸三分处，并非指整个乳房。男子的命门在丹田，所以以下丹田为气穴；女子的命门在乳房，所以以乳房为气穴。阳极变阴，从气穴化生阴血并流行于体外，所以要斩断赤龙（停止月经），必须在阴气产生的地方用功。长久坚持修行，形体自然隐没。如果把男子脐下一寸三分的气穴当作女子的气穴，那就错了。
每当花开对月之时，公羊正想要触碰篱笆。
劝你确信时机到来不要延误，不要等到赤龙（月经）流出水边才行动。
《先天玄微》说：女子在未形成之前，父母交合之际，父亲的精先到，母亲的血后行，血包裹精从而形成女形。女子受孕之时，先得到母亲的一两铅气，先生右肾，牵一条丝线向上生出双眼；牵一条丝线向下生出金丹。从此以后，十二天生一铢癸水，一百八十天生一两癸水。此后，十五天生一铢癸水，一年生一两癸水，到十四岁时在血海中生十四两癸水，加上之前在胎内带来的一两，共成全一斤之数，即三百八十四铢，对应周天三百八十四度，一年有三百八十四日，易卦三百八十四爻。天地之数，阴极阳生，癸尽铅现，女子十四岁（二七）时天癸降临。十四岁天癸降临后，到二十六个月零七天半，耗去癸水一两，到四十九岁时，癸水已耗尽。女子十四岁开始行经，每月一次，运行不息，与月亮的晦朔周期相同，不差时节。如果差误了时刻，疾病就会发作。所以月月如花开，时时行经。之所以行经，是因为阳变为阴。阳气既已变为阴血，则不可再随意运转。如果乱行妄运，会害死不少人。必须在公羊未触藩篱之前（即月经未来潮前），确信时机到来时用功。《上药灵镜三命篇》说：“月信，不是以经血到来才算月信。‘信’字的意思，就像人在外面，还没回家，但消息先到了。”信至之日，身体自己知道，或者腰腿疼痛，头目不安，不思饮食。这是信至而化成血的时候，乃是气的变化。应当在两天半之前，专心行功，如果等到经行，则赤龙阴精不可把持，乱行妄运会害死不少人。必须等待经后两天半，用白绫擦拭测试，颜色呈黄金色，才是经罢之时。按照之前的功法将其运上去斩断。以上这些话，正是指示人们应当知晓时机来行功。
The female life mechanism primarily involves three aspects, and the purple, white, and yellow luminous energies differ from those of males.
In youth (pre-puberty), the Qi mechanism is located above; in decline (post-menopause), it is located in the middle; and in achieving the Daoist body (successful cultivation), it is located below. This critical juncture must be deeply understood.
The female life mechanisms are three: purple, white, and yellow. The yellow light is where the Dantian generates the Elixir. The white light is where the Taiyuan (Fetal Origin) condenses to form the fetus. The purple light is where the Blood Sea generates blood. Located in the upper part is the Yang Acupoint; in the middle is the Yellow Chamber; and in the lower part is the Dantian.
When a woman is young, Tian Gui (substances promoting reproductive maturity) reaches the quantity of one Jin. The true Yuan Qi of the Dantian is sufficient, and the ascending Blood Yuan generates blood. Extreme Yang transforms into Yin, transforming turbid menstruation into menstrual blood that flows externally. Thus, in youth, the Qi operates from above.
When she declines, Tian Gui is exhausted, and Qi cannot ascend to generate blood. With dryness in the waist and depletion of blood, menstruation ceases. Thus, in decline, the Qi operates from the middle. If one wishes to cultivate the "Dry Body" state (cessation of menstruation for cultivation), one must transport Qi from the Lower Dantian up to the Upper Yang Acupoint. Using Shen Fire (spiritual fire) to fumigate, the menstrual blood turns yellow, then white, then vanishes into nothingness, and the physical form naturally conceals itself. Therefore, achievement begins from below, which differs from men. Failing to recognize this critical juncture means the Elixir cannot be formed.
The Qi Acupoint is none other than the breasts; do not rashly speculate about positions below the navel.
If one does not know the place where Yin is generated, how can one make the Poison Dragon (referring to menstruation) lie dormant?
The Qi Acupoint is also called the Blood Yuan, which is the breast area, located at the center, one inch and three fen deep, not referring to the entire bilateral breasts. In men, the Mingmen (Gate of Life) is in the Dantian, so the Lower Dantian is considered the Qi Acupoint. In women, the Mingmen is in the breasts, so the breasts are considered the Qi Acupoint. Extreme Yang transforms into Yin, generating Yin blood from the Qi Acupoint which flows externally. Therefore, to sever the Red Dragon (stop menstruation), effort must be applied at the place where Yin is generated. Through long-term practice, the physical form will naturally conceal itself. Mistaking the male Qi Acupoint (one inch and three fen below the navel) for the female Qi Acupoint is an error.
Whenever flowers bloom facing the moon, the ram desires to touch the fence.
I advise you to act upon the arrival of the signal without delay, lest you wait until the Red Dragon flows out like water from the shore.
*Qiantian Xuanwei* states: Before a woman is born, during the conjunction of parents' essence and blood, the father's essence arrives first, followed by the mother's blood. The blood wraps the essence to form the female shape. Upon conception, the woman first receives one Liang of Lead Qi from the mother, which first generates the right Kidney. One thread extends upward to form the eyes; another thread extends downward to form the Golden Elixir. From then on, one Zhu of Gui Water is generated every twelve days, and one Liang every 180 days. Thereafter, one Zhu is generated every fifteen days, and one Liang per year. By age fourteen (two sevens), fourteen Liang of Gui Water are generated in the Blood Sea. Combined with the one Liang brought from the womb, this totals one Jin, or 384 Zhu. This corresponds to the 384 degrees of the Heavenly Circuit, 384 days of the year, and 384 lines of the I Ching hexagrams. In the numbers of Heaven and Earth, extreme Yin yields to Yang; when Gui is exhausted, Lead appears. At age fourteen (two sevens), Tian Gui descends. After the descent of Tian Gui at fourteen, over two years, six months, seven days, and half a day, one Liang of Gui Water is consumed. By age forty-nine, it is completely exhausted.
After age fourteen, menstruation occurs once a month, continuously operating, synchronized with the lunar cycle of new moon and full moon, without timing errors. A slight deviation in time leads to illness. Hence, monthly as flowers bloom, menstruation flows regularly. The reason for this flow is the transformation of Yang into Yin. Once Yang has transformed into Yin blood, it should not be arbitrarily circulated. Arbitrary circulation causes harm. Effort must be made before the ram touches the fence (before menstruation arrives). *Shangyao Jingjing Sanming Pian* states: "Menstrual trust (Xin) is not defined merely by the arrival of menstrual blood. The character 'Xin' (trust/message) implies that just as a person outside sends news before returning home, the signal arrives first." On the day the signal arrives, the body knows it intuitively: perhaps waist and leg pain, discomfort in the head and eyes, or loss of appetite. This is the formation of blood due to the arrival of Qi. One should focus on practice two and a half days prior. If menstruation has already started, the Red Dragon's Yin essence cannot be controlled, and arbitrary circulation causes harm. One must wait until two and a half days after menstruation ends. Test with white silk; if the color is golden yellow, the menstruation has ceased. Then, apply the previous methods to transport it upward and sever it. These words precisely instruct people to know the proper timing for practice.
