直体正坐，平手顶天。抱胎叠手，用力贵圆。捏纯阳
诀，垂帘勿愆。旋左右背，提撮谷便。尾闾摆折，叩齿漱玄。行是数者，六六皆然。维虚与静
，鼻息绵绵。风火雷电，云开气旋。橐龠已见，却病延年。
清神静坐，息棼饮泉。服活时气，浃死昼烟。见祖在脑，云升惟渊，多行善事，渐寡世缘。胎
成果结，魔阎避焉。后天而老，蜕形化仙。
凡数息乃初入之工夫。人为物诱已久，一旦离境，不能自主，未凝而复散，故用心息相根据法，拴
系此心。由粗入妙，自一息数至百千息，方得此心离境，渐渐纯熟，而息自调矣，此法最快捷方式，最容易
，最无病，与守丹田、守泥丸、守黄中者不同。
凡息有四种∶曰风，曰喘，曰气，曰息。坐时鼻息有声谓之风，往来频促谓之喘，出入不细谓之气
，绵绵密密谓之息。风则散，喘则戾，气则劳，息则定。所谓调者，但欲其不风不促不喘不劳而已，与
数息不同。调息无意，数息有意。绵绵密密，若存若亡，息调则神自归根，所以谓之胎息。
夫调息久，而神愈凝，而息愈微，又久则鼻中全无呼吸，只有微息在脐上往来，
如婴儿在母腹中一般，所以谓之胎息。息者，心无思，目无视，耳无闻，四体无动
，如种火相似，真意燔结，雌雄相聚，微息绵绵，与虚空同体，自然与虚空同寿。
身体正直端坐，双手平举向上托天。双手交叠如抱婴儿状，用力要圆润柔和。捏出纯阳诀（一种手印），眼睑下垂如帘，不要违背此法。向左右旋转背部，提缩肛门与谷道。尾闾部位摆动折叠，叩击牙齿并吞咽津液。实行这几项动作，重复六六三十六次即可。保持虚空与宁静的状态，鼻息细长连绵。如同风火雷电过后，云开雾散，气机自然旋转。橐龠（指呼吸吐纳的机制）显现，可以祛病延年。
清静心神，静坐调息，饮用清泉般的真气。顺应活时的节气变化，避免死寂如昼烟般的停滞。意念观想祖窍在脑部，云雾上升归于深渊，多行善事，逐渐减少世俗的牵缘。胎功成果结成，邪魔阎罗都会避开。虽处后天却不觉衰老，脱去凡胎化身成仙。
凡是数息，是初入门的功夫。人受外物诱惑已久，一旦脱离环境干扰，心不能自主，念头未凝聚又分散，所以用心息相依的方法，拴系住这颗心。由粗糙进入精妙，从一数息到百千息，才能使心脱离外境，渐渐纯熟，气息自然调和。这种方法最快捷、最容易、最无弊端，与守丹田、守泥丸宫、守黄中穴的方法不同。
呼吸有四种：叫作风、喘、气、息。坐着时鼻息有声称为风，往来频繁急促称为喘，出入不细微称为气，绵绵密密称为息。风则散乱，喘则乖戾，气则劳损，息则安定。所谓调息，只是希望它不风、不促、不喘、不劳罢了，这与数息不同。调息是无意的，数息是有意的。绵绵密密，似有似无，气息调和则神自然归根，所以称之为胎息。
调息久了，神志更加凝定，气息更加微弱，再久一点鼻中完全没有呼吸的感觉，只有微弱的呼吸在脐上往来，就像婴儿在母腹中一样，所以称之为胎息。息的状态，是心没有思虑，眼没有视物，耳没有听声，四肢没有动作，像保存火种相似，真意燃烧凝结，雌雄二气相聚，微息绵绵不断，与虚空同为一体，自然能与虚空同寿。
Sit upright with the body straight, palms flat and facing upward as if supporting heaven. Hold the hands together in a fetal position, applying force that is round and soft. Form the "Pure Yang Mudra" (a specific hand gesture), let the eyelids droop like a curtain, and do not deviate from this method. Rotate the back left and right, lift and contract the anus and Gu Dao (valley gate). Swing and fold the Weilu (tailbone area), click the teeth and swallow the profound fluid (saliva). Perform these few movements, repeating them six times six (36 times) each. Maintain a state of emptiness and stillness, with nasal breaths long and continuous. Like wind, fire, thunder, and lightning clearing away clouds to allow Qi to rotate naturally. Once the Tuoyue (bellows mechanism of respiration) is revealed, diseases are expelled and longevity is extended.
Calm the spirit and sit quietly, regulating breath by drinking spring water-like true Qi. Align with the living Qi of the current season, avoiding stagnation like daytime smoke. Visualize the Zu Qiao (ancestral opening) in the brain, where clouds rise into the abyss. Do many good deeds, gradually reducing worldly attachments. When the fetal work bears fruit, demons and Yama will avoid you. Though in the post-heaven stage, one does not age; shedding the mortal form, one transforms into an immortal.
Counting breaths is the initial practice for beginners. Humans have been tempted by external things for a long time; once separated from their environment, they cannot control themselves. Thoughts scatter before they can coalesce. Therefore, use the method of mind and breath relying on each other to tether this mind. Moving from coarse to subtle, counting from one breath to hundreds or thousands allows the mind to detach from external objects, becoming gradually proficient, and the breath regulates itself. This method is the fastest, easiest, and most free from pathology, differing from methods such as guarding the Dantian, guarding the Niwan Palace, or guarding the Huangzhong.
There are four types of breath: Wind, Panting, Qi, and Breath (Xi). When sitting, nasal breathing with sound is called Wind; frequent and hurried movement is called Panting; unrefined entry and exit is called Qi; continuous and dense breathing is called Breath (Xi). Wind leads to scattering, Panting to perversity, Qi to labor, and Breath (Xi) to stability. What is meant by "regulating breath" is simply desiring it to be neither windy, nor hurried, nor panting, nor labored. This differs from counting breaths. Regulating breath is unintentional; counting breaths is intentional. Continuous and dense, existing yet non-existent, when breath is regulated, the spirit naturally returns to its root, hence it is called Fetal Breath (Taixi).
After regulating breath for a long time, the spirit becomes more concentrated, and the breath becomes finer. After a longer period, there is no sensation of breathing through the nose; only a faint breath moves up and down above the navel, just like an infant in the mother's womb. Hence it is called Fetal Breath (Taixi). The state of Xi is: the heart has no thoughts, the eyes see nothing, the ears hear nothing, and the four limbs move not. It is like preserving a fire ember; true intention burns and consolidates, Yin and Yang gather, fine breaths continue endlessly, merging with the Void, and naturally sharing the longevity of the Void.
