《三清真录》曰∶父母之真阴真阳二气，以精血为胞胎，胎完气足而为形矣。集灵资道，神气相合
而为寿，定矣。大寿一万二千岁，守朴任具，虽亡而道不亡也。中寿一千二百岁，留形住世，道在而身亦
在也。下寿一百二十岁，知之修炼，可以安乐延年；不知修炼，走失耗散。在我者，不为我之所有，
而又外触禁忌，暗除年算。一算为三百日寿，一岁为本数之寿，一纪为正
纪之寿。无知少学，以小恶为无伤，积恶以致于灭身；以小损为无害，积损以致于灭生。始以减一算，
次以除本数，终以除一纪，未及中年，夭之大半。仙子真人，怜而哀之。虽有超脱之法，必先养寿之方。
审而用之，可延至大寿。不惮修持，于日自有超凡之道。
《西山记》曰∶虽知养生之理，不悟修行之法，则生亦不长；虽知修炼之方，不知养寿之道，则
修亦无验。故养寿者，凡以禁忌而防其祸。行不多言，恐神散而损气；睡不张口，恐气泄而损神。临危登峻则
神飞，玩杀看斗则气结，吊死问病则喜神自散，卧湿当风则真气日弱。古庙凶祠不可入，入之则神惊；
狂禽异兽不可戏，戏之则神恐。对三光濡溺，折人年寿；贺四重深恩，灭人大数。饮宴于圣像之侧，
魂魄不安；坐卧于墓冢之间，精神自散。枯木大树之下，不可息，防九阴之气，触人阳神；深水大泽不
可渡，恐至寒之性，逼人真气。出众花卉不可折，防招妖狂入室；非时果实不可食，防带邪气入腹。
忘言绮语，非患难不可频说，说之减人正寿；肥甘醇酒，非会合不可频饮，饮之除人本禄。负贤忘恩，
必有祸应；轻财毁物，自无福生。大山勿深入，入之必凶；美物勿酷爱，爱之勿吉。损人伤物，以
冤报冤，嫉贤妒能，以怨起怨，虚传妄授，慢友轻师，此类或有触犯，虽得正诀，遇异人，大道未就，
先为此除其寿。以罪当功，竟不能速成也。善养寿者，以法修其内，以理验其外。修内则秘精修气，
安魂清神，形神俱妙，与天地齐年，炼神合道，超凡入圣也。验外则救贫济苦，慈物利人，孝于家，
忠于国，顺于上，怜于下，害不就利，忙不求闲，凡以方便为心，勿以人我介意，方始奉道．多遇至
人，自得真法。及夫下功之后，少有患难，速得圆成，然是修养所致，亦是阴德报之。苟不达养寿之宜，
安得内外齐成乎？
《三清真录》说：父母双方的真阴和真阳二气，以精血为胚胎的基础，胎元完备、元气充足就形成了形体。聚集灵性资助人道修行，神与气相合而成就长寿，这是确定的道理。上寿可达一万二千岁，坚守质朴本性，顺应自然具足，即使形体消亡，大道依然存在。中寿一千二百岁，保持形体驻留世间，道在身也同在。下寿一百二十岁，懂得修炼的人，可以安乐延年；不懂得修炼，精气就会走失耗散。自身拥有的生命，如果不被自己所珍惜掌控，又在外触犯禁忌，暗中扣除寿命。一“算”代表三百天的寿命，一岁是基本数的寿命，一纪是正纪的寿命。无知且缺乏学习的人，认为小恶无伤大雅，积累恶行导致灭身；认为小损无害处，积累损耗导致灭生。开始减少一算，接着扣除本数，最终扣除一纪，未到中年，便夭折了大半。仙子真人怜悯哀叹这些人。虽然有超脱的方法，但必须先有养寿的方术。审慎地运用它，可以延长至大寿。不畏惧修持，每日自然会有超凡的道法。
《西山记》说：虽然知道养生的道理，但不领悟修行的方法，那么生命也不会长久；虽然知道修炼的方术，但不知道养寿的大道，那么修行也没有效验。所以养寿的人，凡是遇到禁忌都要防范灾祸。行动不多说话，恐怕神气涣散而损伤元气；睡觉不张口，恐怕气息外泄而损伤精神。面临危险攀登高处则神志飞扬失控，观看杀生打斗则气机郁结，吊唁死者探望病人则喜神自行消散，睡在潮湿处对着风口则真气日渐虚弱。古老的庙宇凶险的祠堂不可进入，进入则神灵惊恐；疯狂的禽鸟异兽不可嬉戏，嬉戏则心神恐惧。面对日、月、星三光大小便，会折损人的年寿；庆贺四重深恩（指父母生育养育之恩等），会毁灭人的大数。在圣像旁边饮酒宴乐，魂魄不得安宁；坐在坟墓之间坐卧，精神自然散乱。枯木大树之下，不可休息，防备九阴之气，触动人的阳神；深水大泽不可渡过，恐怕极寒的性质，逼迫人的真气。出众的花卉不可采摘，防备招致妖邪狂气入室；不合时令的果实不可食用，防备带有邪气入腹。忘记言语绮语，非患难时不可频繁诉说，诉说会减损人的正寿；肥甘醇酒，非聚会时不可频繁饮用，饮用会扣除人的本禄。辜负贤人忘恩负义，必有祸报回应；轻视财物毁坏物品，自然没有福分产生。大山不要深入，进入必然凶险；美好的事物不要过度喜爱，喜爱就不吉利。损害他人伤害万物，以冤报冤，嫉妒贤能，以怨起怨，虚妄传播胡乱传授，怠慢朋友轻视老师，这类情况如果有触犯，即使得到正确的诀要，遇到异人指点，大道尚未成就，先因此扣除寿命。以罪抵功，终究不能快速成功。善于养寿的人，用方法修养内在，用道理验证外在。修养内在则秘藏精气修炼元气，安定魂魄清净精神，形神俱妙，与天地同寿，炼神合道，超凡入圣。验证外在则救济贫困帮助困苦，慈爱万物利益他人，在家孝顺，对国家忠诚，对上级顺从，对下级怜惜，不追求害利，忙碌不求闲适，凡事以方便为心，不把人和我的界限放在心上，这才算是奉道，多遇到至人，自然得到真法。等到下功夫之后，少有患难，迅速获得圆满成就，这是修养所致，也是阴德回报的结果。如果不通达养寿的适宜原则，怎么能做到内外齐成呢？
According to the *Sanqing Zhenlu* (Record of the Three Pure Ones): The true Yin and true Yang qi of parents, taking essence and blood as the foundation for conception, when the fetus is complete and qi is sufficient, the physical form is established. Gathering spiritual energy to aid Daoist practice, when spirit (Shen) and qi combine, longevity is achieved; this is a fixed principle. The highest longevity reaches twelve thousand years: by preserving simplicity and allowing nature to fulfill its potential, even if the body perishes, the Dao remains. Medium longevity is one thousand two hundred years: retaining the form in the world, the Dao exists while the body also exists. Lowest longevity is one hundred twenty years: those who understand cultivation can enjoy peace and prolong life; those who do not will lose and dissipate their essence. Life within oneself, if not possessed and controlled by oneself, and further violating external taboos, secretly deducts from one's lifespan. One "Suan" (calculation/unit of time) represents three hundred days of life; one year is the lifespan of the base number; one Ji (twelve-year cycle) is the lifespan of the regular cycle. The ignorant and unlearned consider minor evils harmless, accumulating evil until destruction of the body; considering minor losses harmless, accumulating damage until destruction of life. Initially reducing one Suan, then deducting the base number, finally deducting one Ji, before reaching middle age, more than half of the lifespan is lost. Immortals and True Persons pity and mourn them. Although there are methods of transcendence, one must first have methods for nurturing longevity. Prudently applying these, one can extend life to the highest longevity. Not fearing cultivation, one naturally possesses transcendent Dao daily.
According to the *Xishan Ji*: Although one knows the principles of health preservation, without comprehending the methods of practice, life will not be long; although one knows the formulas of cultivation, without understanding the Dao of nurturing longevity, practice will yield no results. Therefore, those who nurture longevity prevent disasters through observing taboos. Speaking little during activity prevents the dispersion of spirit and damage to qi; sleeping with the mouth closed prevents the leakage of qi and damage to spirit. Climbing heights in danger causes spirit to fly away uncontrollably; watching killings and fights causes qi to knot; mourning deaths and visiting the sick causes joyful spirit to scatter; lying in dampness and facing wind causes true qi to weaken daily. Ancient temples and ominous shrines should not be entered, as entry startles the spirit; wild birds and strange beasts should not be played with, as play frightens the spirit. Urinating or defecating facing the Sun, Moon, and Stars reduces human lifespan; celebrating the four profound debts (such as parental kindness) destroys one's major destiny number. Banqueting beside sacred statues unsettles the soul and spirit; sitting and lying among tombs scatters the spirit and mind. Resting under dead trees or large trees is inadvisable to guard against Nine Yin Qi touching the Yang spirit; crossing deep waters and large marshes is dangerous due to extreme cold forcing out true qi. Picking outstanding flowers invites demonic madness into the house; eating out-of-season fruits allows evil qi to enter the abdomen. Avoiding flowery speech, one should not speak frequently unless in distress, as speaking reduces normal lifespan; avoiding rich, sweet, and alcoholic drinks, one should not drink frequently unless at gatherings, as drinking deducts basic fortune. Betraying the worthy and forgetting gratitude brings inevitable retribution; despising wealth and destroying objects generates no blessings. Do not deeply enter large mountains, as it leads to disaster; do not excessively love beautiful things, as attachment brings misfortune. Harming others and damaging things, repaying injustice with injustice, envying the worthy and jealous of ability, starting resentment with resentment, spreading falsehoods and teaching recklessly, slacking friends and slighting teachers—if such violations occur, even if one receives correct instructions and meets extraordinary people, before the Great Dao is accomplished, lifespan is deducted for these acts. Crimes offsetting merits result in failure to achieve rapid success. Those good at nurturing longevity cultivate internally by method and verify externally by principle. Cultivating internally means guarding essence, refining qi, calming the soul, and purifying spirit, achieving subtlety of form and spirit, aligning with Heaven and Earth, refining spirit to merge with Dao, and becoming transcendent and saintly. Verifying externally means saving the poor, aiding the distressed, showing compassion to all things, benefiting people, being filial at home, loyal to the state, obedient to superiors, and compassionate to subordinates; seeking neither harm nor profit, busyness without seeking leisure, maintaining a heart of convenience, not dwelling on self and other distinctions—this is how one serves the Dao, often meeting supreme persons and naturally obtaining true methods. After putting in effort, few hardships occur, and swift completion is achieved; this is due to cultivation and also the reward of hidden virtue. If one does not understand the appropriateness of nurturing longevity, how can internal and external achievements be synchronized?
