苍天之气，清静则志意治，顺之则阳气固，虽有贼邪，弗能害也，此因时之序。故圣人传精神，服天气，而通神明。
失之则内闭九窍，外壅肌肉，卫气散解，此谓自伤，气之削也。是以圣人陈阴阳，筋脉和同，骨髓坚固，气血皆从。如
是则内外调和，邪不能害，耳目聪明，气立如故。（见疾病类五。）
惟贤人上配天以养头，下象地以养足，中傍人事以养五脏。（阴阳四。）
圣人日避虚邪之道，如避矢石然，邪弗能害，此之谓也。（运气三十五。）
夫阴阳之气，清静则生化治，动则苛疾起。（运气三十二。）
人神不守，非达至真。至真之要，在乎天玄，神守天息，复入本元，命曰归宗。（运气四十三。）
夫精者，身之本也，故藏于精者，春不病温。（疾病二十七。）
冬日在骨，蛰虫周密，君子居室。（脉色九。）
能知七损八益，则二者可调，不知用此，则早衰之节也。年四十而阴气自半也，起居衰矣。年五十，体重，耳目不

故养神者，必知形之肥瘦，营卫血气之盛衰。血气者，人之神，不可不谨养。（针刺十三。）
所有自来肾有久病者，可以寅时面向南，净神不乱思，闭气不息七遍，以引颈咽气顺之，如咽甚硬物，如此七遍后，
饵舌下津令无数。慎其大喜欲情于中，如不忌，即其气复散也，心欲实，令少思。慎勿大怒，怒必真气却散之。欲令脾
实，气无滞饱，无久坐，食无大酸，无食一切生物，宜甘宜淡。悲伤即肺动，而真气复散也，人欲实肺者，要在息气也。
（运气四十一。）
饮食自倍，肠胃乃伤。（疾病六十七。）
阴阳和平之人，居处安静，无为惧惧，无为忻忻，婉然从物，或与不争，与时变化，尊则谦谦，谭而不治，是谓至
治。（藏象三十。）
上天的气候，保持清静平和，人的志意就能安定；顺应这种规律，阳气就能固密，即使有贼邪之气，也不能伤害人体，这是遵循四时时序的结果。所以圣人能够聚精会神，服受天气，从而通达神明。
如果违背了这一规律，就会导致内部九窍闭塞，外部肌肉壅滞，卫气涣散解离，这叫做自我损伤，是正气削弱的表现。因此，圣人调理阴阳，使筋脉调和一致，骨髓坚固，气血运行顺畅。像这样内外协调和谐，邪气就不能侵害，耳目灵敏聪明，气的生化功能如同往常一样正常。（参见疾病类第五节。）
只有贤人上法天以养护头部，下法地以养护足部，中借人事以养护五脏。（参见阴阳第四节。）
圣人对待虚邪贼风的侵袭，就像躲避箭矢和石块一样小心，邪气便不能伤害人体，说的就是这种情况。（参见运气第三十五节。）
阴阳之气，清静平和则生化有序，躁动不安则苛细的疾病就会发生。（参见运气第三十二节。）
人的精神如果不守舍，就不是达到了至真境界。至真的关键，在于天玄之道，精神守住天息，重新回归本元，这就叫做归宗。（参见运气第四十三节。）
精，是身体的根本，所以善于藏精的人，春天就不会患温病。（参见疾病第二十七节。）
冬天寒气深入骨骼，蛰伏的虫子严密包裹自己，君子也居住在室内。（参见脉色第九节。）
懂得“七损八益”的道理，那么阴和阳就可以调节平衡；不懂得运用这个道理，就是早衰的征兆。人到四十岁，阴气自然减半，起居生活就开始衰退了。五十岁时，身体沉重，耳目不聪明了。六十岁时，阳痿，气大衰，九窍不通利，下虚上实，鼻涕眼泪都会流出。所以说，懂得了这些道理就强壮，不懂就衰老，虽然同出一源但名称不同罢了。智者观察事物的共同点，愚者只看到差异；愚者总是感到不足，智者总是感到有余；有余则耳目聪明，身体轻便强健，老人可以恢复壮实，壮年人可以更加健康。因此，圣人从事无为的事业，乐于恬淡的能事，在虚无的境界中顺从欲望、快慰心志，所以寿命无穷，与天地共存，这是圣人修养自身的方法。（参见阴阳第二节。）
所以调养精神的人，必须知道形体的肥瘦，营卫血气的盛衰情况。血气，就是人的精神所在，不可不谨慎调养。（参见针刺第十三节。）
凡是患有久病的人，可以在寅时面向南方，精神清净不乱想，憋气不呼吸七次，然后伸长脖子咽气顺导它，就像吞咽很硬的东西那样。这样做七遍之后，吞咽舌下的津液，数量不限。要慎重防止大喜等情志郁结在心中，如果不忌讳，真气就会再次涣散；要使心气充实，就要减少思虑。千万不要大怒，大怒必然导致真气耗散。要使脾气充实，饮食不要过饱，不要久坐，食物不要太酸，不要吃一切生冷活物，适宜吃甘味和淡味的食物。悲伤会使肺动，导致真气再次涣散；人要使肺气充实，关键在于调息。（参见运气第四十一节。）
饮食过量一倍，肠胃就会受伤。（参见疾病第六十七节。）
阴阳和平的人，居住处所安静，没有恐惧之心，也没有过分欣喜之情，柔顺地随顺万物，或者与人不争，随着时令变化而变化，尊贵却谦逊，谈论而不强加治理，这叫做最高的治理。（参见藏象第三十节。）
The Qi of the High Heaven, when clear and tranquil, allows the will (Zhiyi) to be regulated; following this leads to the consolidation of Yang Qi. Even if pathogenic factors (Zexie) are present, they cannot cause harm; this is due to adhering to the sequence of seasons. Therefore, the Sages concentrate their spirit, receive the Qi of Heaven, and communicate with divine illumination.
If one deviates from this, internal orifices become blocked, external muscles become obstructed, and Defensive Qi (Wei Qi) scatters and dissipates. This is called self-injury, a weakening of Qi. Thus, the Sages arrange Yin and Yang, harmonize sinews and vessels, solidify marrow, and ensure Qi and Blood flow smoothly. In such a state, interior and exterior are harmonized, pathogens cannot harm, ears and eyes are acute and bright, and the establishment of Qi remains as before. (See Category of Diseases, Section 5.)
Only the Virtuous Ones emulate Heaven above to nourish the head, emulate Earth below to nourish the feet, and follow human affairs in the middle to nourish the Zang-Fu organs. (Yin-Yang, Section 4.)
The Sages avoid empty pathogens (Xu Xie) as they would avoid arrows and stones, so that pathogens cannot harm them; this is what is meant. (Movement of Qi, Section 35.)
The Qi of Yin and Yang, when clear and tranquil, results in orderly generation and transformation; when agitated, severe diseases arise. (Movement of Qi, Section 32.)
If the Spirit (Shen) does not reside within, it is not attaining the Ultimate Truth. The essence of the Ultimate Truth lies in the Heavenly Mystery. When the Spirit guards the Heavenly Breath and returns to the Original Source, it is called Returning to the Root. (Movement of Qi, Section 43.)
Essence (Jing) is the root of the body. Therefore, those who preserve Essence will not suffer from Warmth diseases in Spring. (Diseases, Section 27.)
In winter, cold penetrates to the bones, hibernating insects wrap themselves tightly, and gentlemen dwell indoors. (Pulse and Color, Section 9.)
One who understands the "Seven Losses and Eight Benefits" can regulate both [Yin and Yang]; one who does not use this principle exhibits signs of premature aging. At forty years old, Yin Qi naturally halves, and daily activities decline. At fifty, the body feels heavy, and hearing and vision become dull. At sixty, impotence occurs, Qi greatly declines, the nine orifices are unsmooth, deficiency at the lower part and excess at the upper part prevail, and tears and snot flow freely. Thus it is said: knowing these makes one strong, not knowing makes one old. Although originating from the same source, names differ. The wise observe similarities, the foolish observe differences. The foolish feel insufficient, the wise feel abundant. Abundance leads to acute hearing and vision, and a light, strong body; the elderly regain vigor, and the vigorous become even healthier. Therefore, the Sages engage in non-action (Wu Wei), delight in tranquility, and satisfy desires within the realm of emptiness. Thus, their lifespan is infinite, lasting until Heaven and Earth end. This is how the Sages cultivate themselves. (Yin-Yang, Section 2.)
Therefore, those who nourish the Spirit must know the fatness or thinness of the form, and the prosperity or decline of Ying-Qi, Wei-Qi, Blood, and Qi. Blood and Qi are the Spirit of humans; they must be carefully nourished. (Acupuncture, Section 13.)
For all those suffering from chronic kidney disease, one should face south at the Yin hour (3-5 AM), keep the spirit pure without chaotic thoughts, hold the breath for seven cycles, extend the neck, and swallow the Qi as if swallowing a hard object. After doing this seven times, swallow the saliva under the tongue without limit. Be cautious against excessive joy or emotional turmoil within; if not guarded against, the Qi will scatter again. To make Heart Qi substantial, reduce thinking. Do not become extremely angry, as anger causes True Qi to scatter. To make Spleen Qi substantial, avoid overeating, prolonged sitting, overly sour foods, and raw/uncooked foods; prefer sweet and bland flavors. Grief moves the Lungs and causes True Qi to scatter again. To make Lung Qi substantial, the key lies in regulating the breath. (Movement of Qi, Section 41.)
If food and drink exceed by double, the intestines and stomach are injured. (Diseases, Section 67.)
Individuals with balanced Yin and Yang live quietly, without fear or excessive joy, gently following things, avoiding conflict, changing with the times, being noble yet humble, discussing without imposing control. This is called supreme governance. (Zang-Fu Images, Section 30.)
