人生世间，无论贤愚仙凡，富贵贫贱，俱有返归之期。儒家谓之全终，释家谓之坐脱，道家谓之
羽化。圣贤仙佛，全始全归，志气清明，故上而伸之为神。庸愚昏暗，气尽力竭，神志仿佛，故返而归
之为鬼。神鬼关头，在此攸分。此时固宜仔细把握，而平日尤当时时警觉，念念不忘，寡尤寡悔，
寡过寡欲，保身有方，养身有术，日新又新，永无间断，阳之精聚，阴之灵结，纯阴纯阳，菁华积而
成为轻清上浮气象，则元神主宰，返本归原，身至阳极阴极之区，毫无损折，何难与仙佛圣贤，同拜金
母木公也哉？！若不明修炼，清浊混身，不特不能使纯阳之气升而又升，直接上清，纯阴
之气降而又降，下临无地，即此半阴半阳之世，恐亦难保长生矣！
修养必先运气者，盖以气为精神枢纽，并为一身枢纽耳。精之在身，如水之在地。精之发源于
天河，注于脏腑，达于肢体，如水之发源于昆仑，散于沟渎，会于河海。身之有神，是运气化精之
主宰。而气则如二气之流行于四时，分散于四方，下降上腾，清升浊降。阳之积而成日，阴之凝而
成月。日月营运，一寒一暑，能使形形色色，化生无穷，始而复终，终而复始，生机遂以不绝。人
若知导引诸法，虽起居饮食，偶失时节，一为吸浊呼清，俾轻浮重凝，而血脉筋络通达无滞，则窍窍
玲珑，节节流通，亦能使寒热瘟疫化为乌有。至功力已到，搬运渐熟，呼吸顷刻，上至天庭，下堕
海底，中及四肢，三焦谐畅，百体调和，纵有微恙，登时即除，安能为殃？譬之阳极阴极之时，郁
而积为烈风迅雷，阴云淫雨，雪雹酷日之灾。一经二气营运，分阴分阳，终无天昏地惨，天崩地裂之
变，久仍归于阴阳平而四时和也。天地之气，岂自开辟，即失其常哉。亦由人心不古，呼吸达
天，天人相应，积而生变，所以上古天时与晚近不同。皇初人寿与后世不同，坟典所在，不尽荒谬
妄诞也。人能运气生精，使精生神，则五脏六腑十二经络，以及四肢百体，毫毛皮肤，皆有光天化日
气象，无嶂翳昏迷境界，不亦羲皇上人哉？！谚语云∶人亦小天地，洵不诬也。古仙人云∶服气不死。
又曰∶还丹永命，气是添年药，心为使气神，若知行气诀，便是学仙人。皆为导引逆流而发也。修炼
之土可不留心于呼吸哉？！
人生在世，无论贤能愚笨、神仙凡人，还是富贵贫贱，都有回归本源的时刻。儒家称之为“全终”（善始善终），佛家称之为“坐脱”（端坐离世），道家称之为“羽化”（成仙飞升）。圣贤仙佛能够善始善终，志气清明，所以向上伸展化为神。平庸愚昧之人，气尽力竭，神志恍惚，所以向下回归化为鬼。神与鬼的分野，就在于此。这个时候固然应该仔细把握，而平日更应当时时警觉，念念不忘，少犯过错少生悔恨，减少过失减少欲望，有方法保养身体，有技术调养身心，日日更新永无间断，使阳之精华聚集，阴之灵韵凝结，达到纯阴或纯阳的境界，当菁华积聚形成轻清上浮的气象时，元神成为主宰，返本归原，身体到达阳极阴极的领域，毫无损伤折损，又怎能难与仙佛圣贤一同拜见金母木公呢？！如果不明白修炼，清浊之气混杂于身，不仅不能使纯阳之气升而又升，直接上达清虚之境，也不能使纯阴之气降而又降，下临无地，即便在这半阴半阳的人世间，恐怕也难以保全长生啊！
修养必须先运行气息，是因为气是精神的枢纽，也是全身的枢纽。精存在于体内，就像水存在于大地。精发源于天河，注入脏腑，通达肢体，就像水发源于昆仑山，散布于沟渠，汇聚于河海。身体拥有神，是运气转化精的主宰。而气则像阴阳二气在四季中流行，分散于四方，下降上升，清气上升浊气下降。阳气积聚而成日，阴气凝结而成月。日月运转，一寒一暑，能使形形色色的事物化生无穷，开始后又结束，结束后又开始，生机因此不绝。人如果懂得导引等方法，即使起居饮食偶尔失去时节，只要做到吸浊呼清，使轻浮者重凝，血脉筋络通达无滞，那么窍窍玲珑，节节流通，也能使寒热瘟疫化为乌有。等到功力深厚，搬运逐渐熟练，呼吸顷刻间，上至天庭，下堕海底，中及四肢，三焦和谐通畅，百体调和，纵有微小病痛，顿时即除，怎么能为祸害呢？这好比阳极阴极之时，郁结积累为烈风迅雷、阴云淫雨、雪雹酷日等灾害。一旦经过二气运转，分阴分阳，最终不会有天昏地惨、天崩地裂的变化，长久之后仍归于阴阳平衡而四时和谐。天地之气，难道自从开辟以来就失去常态吗？也是因为人心不古，呼吸通达上天，天人相应，积累而产生变化，所以上古的天时与近代不同。皇初时期的人寿与后世不同，坟典记载并非全是荒谬妄诞。人如果能通过运气产生精，使精产生神，那么五脏六腑十二经络，以及四肢百体、毫毛皮肤，都有光天化日的气象，没有障翳昏迷的境界，这不就是羲皇上人吗？！谚语说：人也是小天地，确实不假。古代仙人说：服气可以不死。又说：还丹可以永命，气是添年药，心是驾驭气的神，如果知道行气的诀窍，就是学习做仙人。这些都是为了导引逆流而发的言论。修炼之士能不留心于呼吸吗？！
In this world, whether wise or foolish, immortal or mortal, rich or poor, everyone has a time to return to the origin. Confucianism calls it "Quan Zhong" (completing life with dignity), Buddhism calls it "Zuo Tuo" (passing away while sitting in meditation), and Daoism calls it "Yu Hua" (ascending as an immortal). Sages, immortals, and Buddhas complete both beginning and end, with clear will and spirit, thus expanding upward to become spirits. The mediocre and ignorant, whose qi is exhausted and spirit confused, return downward to become ghosts. The distinction between spirits and ghosts lies here. This moment should indeed be carefully grasped, but even more so should one be vigilant daily, constantly mindful, minimizing faults and regrets, reducing errors and desires, preserving the body with proper methods, nurturing the body with techniques, renewing oneself day by day without interruption. When the essence of Yang gathers and the spirit of Yin condenses, reaching pure Yin or pure Yang states, and when the quintessence accumulates to form a light, clear, and floating aura, the Primordial Spirit becomes the master, returning to the root and origin. If the body reaches the realms of extreme Yang and extreme Yin without any damage, how could it be difficult to bow together with immortals, Buddhas, and sages before Mother Jin and Lord Mu?! If one does not understand cultivation, mixing clear and turbid energies within the body, not only can one not make pure Yang energy rise again and again directly to the highest clarity, nor can one make pure Yin energy descend again and again to the lowest depths, but even in this semi-Yin semi-Yang world, preserving longevity would be difficult!
Cultivation must begin with moving Qi, because Qi is the pivot of spirit and also the pivot of the whole body. Jing (Essence) in the body is like water on earth. Jing originates from the Heavenly River, pours into the Zang-Fu organs, and reaches the limbs, just as water originates from Kunlun Mountain, scatters into ditches, and converges into rivers and seas. The Shen (Spirit) in the body is the master that transforms Qi into Jing. And Qi flows like the two energies through the four seasons, disperses in the four directions, descends and ascends, with clear rising and turbid sinking. Yang accumulates to form the Sun, Yin condenses to form the Moon. The operation of Sun and Moon, alternating cold and heat, allows all forms of life to generate endlessly, starting and ending, ending and starting, so that the vitality of life never ceases. If humans know methods of Daoyin (guiding and pulling), even if daily routines and diet occasionally lose their timing, as long as one inhales turbidity and exhales clarity, making light things heavy and condensed, and ensuring blood vessels and meridians are unobstructed, then every aperture will be exquisite, every joint flowing smoothly, which can also dispel cold, heat, and plagues. When skill is profound and manipulation becomes familiar, breaths in moments reach the Heavenly Court above, the Sea Bottom below, and the four limbs in between, the San Jiao (Triple Burner) harmonizes and flows freely, the hundred bodies regulate, and even slight ailments are removed instantly; how can they cause harm? It is like at times of extreme Yang and extreme Yin, stagnation accumulates into fierce winds, thunderstorms, dark clouds, torrential rains, hail, and scorching sun disasters. Once the two energies operate, dividing Yin and Yang, there will ultimately be no sky-darkening, earth-cracking catastrophes, and eventually returning to Yin-Yang balance and harmonious four seasons. Did the Qi of Heaven and Earth lose its normal state since creation? It is also due to the decline of human hearts, where breath connects to Heaven, Heaven and Man correspond, accumulation leads to change, so ancient heavenly times differ from recent ones. Lifespans in the primordial era differ from later generations; records in ancient texts are not entirely absurd. If humans can generate Jing through moving Qi, and generate Shen through Jing, then the five Zang and six Fu organs, twelve meridians, four limbs, hundred bones, hair, and skin will all possess the aura of bright daylight, free from obscurity and confusion, is this not being like people of the羲皇 (Fuxi) era?! As the proverb says: Humans are small heavens and earths, truly not false. Ancient immortals said: Taking in Qi prevents death. Also said: Returning Elixir ensures eternal life; Qi is the medicine for adding years, Heart is the god driving Qi. If one knows the secrets of moving Qi, one is learning to be an immortal. These words all advocate reversing the flow through Daoyin. Should cultivators not pay attention to breathing?!
