本云，何也？太极乃一气耳，太极生两仪，两仪生四象，四象生五行，五行备而万物生矣。当两仪未判之先，总一太极

且妇人怀孕，其各经逐月滋养胎元，皆有次第。一月足厥阴肝脉养，二月足少阳胆脉养，三月手厥阴心包络脉养，四月
手少阳三焦脉养，五月足太阴脾脉养，六月足阳明胃脉养，七月手太阴肺脉养，八月手阳明大肠脉养，九月足少阴肾脉

汁故也。若孕妇病而胎不安，就子所养月分，详其气血多寡，察其有余不足而调之。
万物都生长在造化之中，必定依赖元气的累积，逐渐形成形体。胎儿在母腹中，也依赖气血的滋养生长，逐渐形成身体。人和物的生命，都有它的根本，为什么呢？太极就是一气罢了，太极生两仪，两仪生四象，四象生五行，五行具备而万物就产生了。当两仪尚未分辨之前，总归是一个太极。太极就像卵一样，内部阴阳混沌不清，到了开辟时才分出天地，轻清之气上升为天，重浊之气下沉为地。天显现出日月星辰的景象，地奠定了山川土石的形式，这就是两仪生四象。四象具备而五行彰显，一生水，水完全清澈，没有渣滓；二生火，火则熏灼浑浊且将要凝固；三生木，木则半刚半柔，体质便形成了；四生金，完全至刚，体质坚硬；五生土，土则重大，质地浓厚而形成形体，这样五行就具备了。五行既已具备，那么阴阳交合，就能化生万物。人得到天地的正气而生，既有阴阳，就分男女，所以禀受乾道精粹的是男性，禀受坤道精粹的是女性，他们是汇聚了五行的秀气，得到了气化完整的人。所以头圆象征天，脚方象征地，两眼象征日月，四肢象征四季，五脏象征五行，六腑象征六气，呼吸象征气机，醒睡象征昼夜，血脉象征江河，毛发象征草木，骨节象征周天的度数。一身之中，无不效法天地，人是天地间最灵秀的生物。上用来制定历法明确时节，下用来划分州野疆界，中间用来确立纲常伦理。辅助天地所不及之处，裁成天地所过分之处，所以能参赞天地成为三才之一。那些动物中成为兽类的，禀受了阴阳的偏颇，头体横卧，四肢都用足行走。那些动物中成为禽类的，禀受了阴阳的盛气，头向上，有翅膀能飞。那些动物中成为水族的，禀受了阴阳的极致，无翼无足而沉于水中。植物本源于地，所以根深入地下，枝叶朝向天空，这都是造化的自然妙处。现在从人的形体变化来说。《易经》说：男女交合精气，万物化生，大概是精血会聚，胎孕才得以形成。胎儿一月如露珠，二月如桃花，三月男女性别分明，四月形象具备，五月筋骨形成，六月毛发生长。七月游荡其魂而能活动左手，八月游荡其魄而能活动右手，九月三次转身，十月满足而生。又说：一月为胞，是精血凝结。二月为胎，是形体的胚胎兆象。三月阳神为主魂，动而生灵（三魂，一曰爽灵，二曰胎光，三曰幽精）。四月阴灵为七魄，静以镇形（七魄，一名尸狗，二名伏矢，三名雀阴，四名吞贼，五名非毒，六名除秽，七名臭肺）。五月五行分属五脏，以安神。六月六律定属六腑，用以滋灵。七月七精开启窍穴，通光明。八月八景神具备，降真灵。九月宫室罗列分布，以定精。十月气足，万象成就。又有说法：脏腑生成的次序，若阴包阳者为男，先生左肾；阳包阴者为女，先生右肾。其次肾生脾，脾生肝，肝生肺，肺生心，这是相生其所胜者。肾属水，所以五脏由此定为阴。其次心生小肠，小肠生大肠，大肠生胆。胆生胃，胃生膀胱，膀胱生三焦，这是生其所不胜者。小肠属火，所以六腑由此定为阳。其次三焦生奇经八脉，八脉生十二经脉，十二经脉生十五络脉。十五络脉生一百八十系络，系络生一百八十缠络，缠络生三万四千孙络，孙络生三百二十五骨节，骨节生三百二十五大穴，大穴生八万四千毛窍，这样耳、目、口、鼻、四肢、全身骨骼都已具备。况且妇女怀孕，各条经脉逐月滋养胎元，都有次第。一月足厥阴肝脉滋养，二月足少阳胆脉滋养，三月手厥阴心包络脉滋养，四月手少阳三焦脉滋养，五月足太阴脾脉滋养，六月足阳明胃脉滋养，七月手太阴肺脉滋养，八月手阳明大肠脉滋养，九月足少阴肾脉滋养，十月足太阳膀胱脉滋养，所有阴阳经脉各养儿三十日，只有手太阳小肠经和手少阴心经这两条经脉不直接滋养，因为前者主管月经，后者化为乳汁的缘故。如果孕妇生病而胎不安稳，就要根据胎儿所养的月份，详细考察气血的多寡，观察有余还是不足来进行调理。
All things are born within the process of creation, relying on the accumulation of Yuan Qi (Primordial Qi) to gradually take form. A fetus in the womb also relies on the nourishment and growth of Qi and Blood to gradually form its body. Why do all living beings have a fundamental origin? Taiji is but one Qi. Taiji generates Liangyi (Two Polarities), Liangyi generates Sixiang (Four Images), and Sixiang generates Wuxing (Five Phases). When Wuxing are complete, all things are generated. Before Liangyi were differentiated, there was only Taiji. Taiji is like an egg; internally, Yin and Yang are chaotic. Upon differentiation, Heaven and Earth are separated: light and clear Qi becomes Heaven, while heavy and turbid Qi becomes Earth. Heaven manifests as the sun, moon, and stars; Earth establishes forms as mountains, rivers, soil, and stones. This is how Liangyi generates Sixiang. With Sixiang present, Wuxing become evident: One generates Water, which is entirely clear without dregs; Two generates Fire, which is scorching, turbid, and tends to solidify; Three generates Wood, which is half rigid and half flexible, forming its constitution; Four generates Metal, which is entirely rigid and has a firm constitution; Five generates Earth, which is heavy and dense, taking shape. Thus, Wuxing are complete. Once Wuxing are complete, Yin and Yang interact and combine to transform into all things. Humans are born from the upright Qi of Heaven and Earth. Having Yin and Yang, they are divided into male and female. Those who inherit the essence of Qian Dao (Heavenly Principle) are male, and those who inherit the essence of Kun Dao (Earthly Principle) are female. They gather the elegance of Wuxing and possess the completeness of Qi transformation. Therefore, the head is round symbolizing Heaven, the feet square symbolizing Earth, the two eyes symbolize the Sun and Moon, the four limbs symbolize the Four Seasons, the Zang Organs (Solid Organs) symbolize Wuxing, the Fu Organs (Hollow Organs) symbolize the Six Qi, respiration symbolizes Qi mechanism, waking and sleeping symbolize day and night, blood vessels symbolize rivers, hair symbolizes vegetation, and joints symbolize the degrees of the celestial sphere. Within the human body, nothing does not resemble Heaven and Earth; humans are the most spiritual among creatures. Above, they regulate calendars and clarify seasons; below, they divide provinces and demarcate territories; in the middle, they establish ethical codes and order. They assist where Heaven and Earth fall short and moderate where Heaven and Earth exceed, thereby participating in Heaven and Earth to become one of the Three Powers (San Cai). Animals that move as beasts inherit biased Yin and Yang, lying horizontally with four legs for walking. Animals that move as birds inherit abundant Yin and Yang, holding their heads up with wings for flight. Animals that move as aquatic life inherit extreme Yin and Yang, having no wings or feet, sinking into water. Plants originate from Earth; thus, roots enter the ground while branches and leaves face the sky. These are all the natural wonders of creation. Now speaking of human morphogenesis: The *I Ching* states, "When male and female couple their essence, all things are transformed." Essentially, when Essence and Blood converge, conception occurs. In the first month, the embryo is like dew; in the second, like peach blossoms; in the third, gender is distinguished; in the fourth, physical features are complete; in the fifth, bones and sinews form; in the sixth, hair grows. In the seventh month, the Hun Soul (Ethereal Soul) wanders, enabling movement of the left hand; in the eighth month, the Po Soul (Corporeal Soul) wanders, enabling movement of the right hand; in the ninth month, it turns three times; in the tenth month, it is fully developed and born. It is also said: The first month is the Bao (Womb/Cell), where Essence and Blood coagulate. The second month is the Tai (Fetus), where the form's embryo takes shape. In the third month, Yang Shen (Spirit) acts as the main Hun Soul, moving to generate life (The Three Hun Souls: 1. Shuangling, 2. Taiguang, 3. Youjing). In the fourth month, Yin Ling acts as the Seven Po Souls, stilling and stabilizing the form (The Seven Po Souls: 1. Shigou, 2. Fushi, 3. Queyin, 4. Tunzei, 5. Feidu, 6. Chuwei, 7. Choufei). In the fifth month, Wuxing are distributed among the Zang Organs to calm the Spirit. In the sixth month, Liulü (Six Pitch Pipes) determine the Fu Organs to nourish the Spirit. In the seventh month, Jingqi (Essence) opens the orifices to transmit brightness. In the eighth month, Bajing (Eight Scenes) deities are complete, descending true spirits. In the ninth month, palaces are arranged to stabilize Essence. In the tenth month, Qi is sufficient, and all phenomena are formed. Another view states: Regarding the sequence of Zang and Fu organ formation, if Yin envelops Yang, it is male, and the Left Kidney forms first; if Yang envelops Yin, it is female, and the Right Kidney forms first. Next, Kidney generates Spleen, Spleen generates Liver, Liver generates Lung, and Lung generates Heart, generating what it overcomes. Since Kidney belongs to Water, the five Zang Organs are thus defined as Yin. Next, Heart generates Small Intestine, Small Intestine generates Large Intestine, Large Intestine generates Gallbladder. Gallbladder generates Stomach, Stomach generates Bladder, and Bladder generates Sanjiao (Triple Burner), generating what overcomes it. Since Small Intestine belongs to Fire, the six Fu Organs are thus defined as Yang. Next, Sanjiao generates the Eight Extraordinary Vessels, Eight Extraordinary Vessels generate the Twelve Meridians, Twelve Meridians generate the Fifteen Collaterals. Fifteen Collaterals generate 180 Xi-Luo (Connecting Collaterals), which generate 180 Chan-Luo (Entwined Collaterals), which generate 34,000 Sun-Luo (Sun Collaterals), which generate 325 bone joints, which generate 325 major acupoints, which generate 84,000 hair pores. Thus, ears, eyes, mouth, nose, limbs, and the entire skeletal structure are complete. Furthermore, during pregnancy, each meridian nourishes the fetal origin monthly in a specific sequence. Month 1: Foot Jueyin Liver Meridian nourishes. Month 2: Foot Shaoyang Gallbladder Meridian nourishes. Month 3: Hand Jueyin Pericardium Meridian nourishes. Month 4: Hand Shaoyang Sanjiao Meridian nourishes. Month 5: Foot Taiyin Spleen Meridian nourishes. Month 6: Foot Yangming Stomach Meridian nourishes. Month 7: Hand Taiyin Lung Meridian nourishes. Month 8: Hand Yangming Large Intestine Meridian nourishes. Month 9: Foot Shaoyin Kidney Meridian nourishes. Month 10: Foot Taiyang Bladder Meridian nourishes. All Yin and Yang meridians nourish the fetus for thirty days each. Only the Hand Taiyang Small Intestine Meridian and Hand Shaoyin Heart Meridian do not directly nourish, because the former governs menstruation and the latter transforms into breast milk. If a pregnant woman falls ill and the fetus is unstable, one must examine the abundance or deficiency of Qi and Blood according to the month of nourishment and adjust accordingly.
