我曾经阅读过齐国大夫褚氏的遗书。书中首先论述了受胎成形的问题，说道：男女交合时，双方情意通畅，如果阴血先到达，阳精随后冲击，血液张开包裹住精液，精液进入成为骨骼的基础，男性的形体就形成了。如果阳精先进入，阴血随后参与，精液张开包裹住血液，血液进入居于根本位置，女性的形体就形成了。如果阴阳同时到达，就会形成非男非女的身体；如果精血分散分布，则是双胎或异体双胞胎的征兆。再阐述这个说法，正如经典所说：男子属阳，得到阴气而生；男子以储藏精气为主，女子以维系胞宫为主。男女之所以有区别，也是由于阴阳先后所禀赋的本源有所不同。想要了解阴阳本源的不同，可以从肾脏来考察。
男子在胚胎发育初期，命门位于右肾，归属于阴而对应太阳（日），主管三魂，降下赤色精气并镇守丹元。所谓丹元，是精气的居所。其象上赤下黑，左青右白，中央黄色运化其中。这是三阳的正气，太一的真正精气，名叫弱水，里面有元龟，用来……至于左肾，归属于阴而对应月亮，主管七魄，降下黑色精气并镇守金关。这大概是阳以阴为根本，必然禀受生于右侧的缘故。
至于女子的发育，则命门位于左肾，归属于阴而对应月亮，主管七魄，降下黑色精气并镇守元宫。所谓元宫，是胞宫所在之处。其象上黑下赤，左白右青，中央黄色运化其中。这是三阴的正气，太一的真正精气，名叫原泉，里面有蛇，用来呼吸元气，营运百脉，是三焦的原动力，并与营气相应。营气属阴，行于脉中，所以女子的命门在乎左肾。至于右肾，则归属于阳而对应太阳，主管三魂，降下赤色精气并镇守玉关。这大概是阴以阳为根本，必然禀受生于左侧的缘故。
根据佛教教义，父母与子女之间有相互感应的业力，神识才进入胎中。根据地、水、火、风四大元素，众缘和合，逐渐得以生长。怀孕第一七日，胎儿形状如同藕根……两七日……四七日……五脏……四七……百吸……名毛……根清……二手……肉。每日血行……十……乐……下……自然生出十一种风，开通集成，使得筋脉肌骨、机关孔窍，都能流通顺畅，然后才能成为人。既然如此，父母生育子女的功劳等同于造化之功，其中的恩情，难道可以说小吗？
再从道教书籍来说，玉清之气，生在人身上部，称为泥丸宫。上清之气，生在人中部，称为绛宫。太清之……百六……西方……量妙……胞命黄演之气在下增添，乃至第九个月，无想、无结、无爱天岳府命元。从此气不再增添。九气既已添足，又有六甲之神，互相保卫而使胎儿完全成型。所谓六甲神，甲子水神，为之调畅血脉，润泽三焦；甲戌土神，为之调理肌肉，使不偏枯；甲申金神，为之紧固爪齿，养育真牙；甲午火神，为之和悦五脏，混合百神；甲辰风神，为之保固胎息，呼吸阴阳；甲寅木神，为之濯炼筋骨，通贯百骸。由此可知，妇人妊娠被称为“六甲”，难道有其他原因吗？五脏六腑、筋骨髓脑、皮肤血脉、精藏水藏，共二万八千处；形彰一万二千处；精光三万六千处；出入八万四千个毛窍，无不各有神灵主宰。既然这样，人生于天地之间，怎能不凝神守真，保全上天赋予我们的本性呢？我收集释家、老庄之言以及前贤的遗论，编辑……
I once read the *Remnant Book* (Yi Shu) of Chu Shi, a minister of Qi. The text begins by discussing conception and formation, stating: When male and female unite, their emotions flow smoothly. If Yin blood arrives first and Yang essence follows to strike, the blood opens to wrap the essence; the essence enters to form bone, and the male form is established. If Yang essence enters first and Yin blood subsequently participates, the essence opens to wrap the blood; the blood enters to reside in the root, and the female form is established. If Yin and Yang arrive simultaneously, a body that is neither male nor female results. If essence and blood are scattered and divided, it is a sign of twin fetuses or heteropagus twins. Elaborating on this theory, as stated in the classics: Men belong to Yang and are born through receiving Yin; men store essence, while women connect to the uterus (Bao Gong). The distinction between men and women arises from the different origins of Yin and Yang received initially. To understand these differences in origin, one may examine the Kidneys.
In males, during early embryonic development, the Mingmen (Gate of Life) resides in the right Kidney. It belongs to Yin but corresponds to the Sun (Yang), governs the Three Souls (San Hun), descends red essence, and stabilizes the Danyuan (Cinnabar Origin). The Danyuan is the residence of essence. Its imagery is red above and black below, green on the left, white on the right, with yellow transforming in the center. This is the true Qi of the Three Yangs, the true Jing of Taiyi, named Ruoshui (Weak Water), containing a primordial turtle, which serves to... As for the left Kidney, it belongs to Yin and corresponds to the Moon, governing the Seven Spirits (Qi Po), descending black essence, and stabilizing the Jinguang (Metal Gate). This is because Yang takes Yin as its root, necessarily inheriting life from the right side.
Regarding females, the Mingmen resides in the left Kidron. It belongs to Yin and corresponds to the Moon, governing the Seven Spirits, descending black essence, and stabilizing the Yuangong (Primal Palace). The Yuangong is where the uterus is attached. Its imagery is black above and red below, white on the left, green on the right, with yellow transforming in the center. This is the true Qi of the Three Yins, the true Jing of Taiyi, named Yuanquan (Source Spring), containing a snake, which breathes Yuan Qi, circulates it through the hundred vessels, serves as the source of the Sanjiao (Triple Burner), and corresponds to Ying Qi (Nutritive Qi). Ying Qi is Yin and travels within the vessels; thus, the female Mingmen is located in the left Kidney. As for the right Kidney, it belongs to Yang and corresponds to the Sun, governing the Three Souls, descending red essence, and stabilizing the Yuguan (Jade Gate). This is because Yin takes Yang as its root, necessarily inheriting life from the left side.
According to Buddhist doctrine, there is mutual karmic感应 (resonance/affinity) between parents and child, allowing the Shen (Spirit/Mind) to enter the fetus. Based on the four elements of Earth, Water, Fire, and Wind, and the harmony of various conditions, growth gradually occurs. On the seventh day, the fetus resembles an lotus root...

Naturally generates eleven types of Feng (Wind/Qi), opening and integrating, so that tendons, vessels, muscles, bones, joints, and orifices all achieve free flow. Only then can the human form be completed. Thus, the功 (merit/effort) of parents in giving birth is equivalent to Creation itself; how could their grace be considered small?
Furthermore, according to Daoist texts, Yuqing Qi (Jade Purity Qi) generates the upper part of the human body, known as Niwan Palace (Mud Pillar). Shangqing Qi (Upper Purity Qi) generates the middle part, known as Jianggong (Crimson Palace). Taiqing Qi... [Text fragments omitted] ... Bao Ming Huangyan Qi adds in the lower section, until the ninth month, when there is no thought, no knot, no love, and Tianyuefu Mingyuan. From then on, Qi is no longer added. Once the Nine Qis are complete, there are also the Six Jia Deities who protect and ensure full formation. These Six Jia Deities include: Jiazi Water Deity, who regulates blood vessels and moistens the Sanjiao; Jiaxu Earth Deity, who regulates muscles to prevent paralysis; Jiashen Metal Deity, who tightens nails and teeth and nourishes the true teeth; Jiawu Fire Deity, who harmonizes the Five Zang Organs and mixes the Hundred Spirits; Jiachen Wind Deity, who secures fetal breath and regulates Yin-Yang respiration; Jiayin Wood Deity, who refines sinews and bones and connects the hundred bones. It is evident that pregnancy in women is called "Six Jia" for this reason alone. The Five Zang and Six Fu Organs, sinews, marrow, bones, brain, skin, blood, vessels, Jing storage, and Water storage total twenty-eight thousand locations; visible forms number twelve thousand; Jing light numbers thirty-six thousand; entering and exiting through eighty-four thousand hair pores—all are governed by specific deities. Therefore, since humans live within Heaven and Earth, how can they fail to concentrate their Shen and guard their Zhen (Truth/True Nature), preserving what Heaven has bestowed upon them? I have compiled statements from Buddhists and Lao-Zhuang followers, along with the remnant theories of former sages, editing...
