When the Liver is diseased, practice the "Xu" (嘘) character mantra with eyes open; when the Lungs are diseased, practice the "Si" (呬) character mantra (original text blank, inferred as "Si") with both hands raised overhead holding up the sky; when the Heart is diseased, practice the "He" (呵) character mantra with hands crossed above the head; when the Kidneys are diseased, practice the "Chui" (吹) character mantra while hugging knees in a squatting position; when the Spleen is diseased, practice the "Hu" (呼) character mantra by puckering the mouth to exhale; when the Sanjiao (Triple Burner) has pathogenic heat, practice the "Xi" (嘻) character mantra and lie down to calm the mind and body.

In Spring, practicing the "Xu" mantra brightens the eyes and strongly nourishes the Liver; at Summer Solstice, practicing the "He" mantra allows Heart Fire to naturally subside; in Autumn, practicing the "Si" mantra ensures Lung Metal is moistened; in Winter, practicing the "Chui" mantra keeps the Kidneys peaceful; for the Sanjiao, practicing the "Xi" mantra removes vexation and heat; throughout the four seasons, frequently practicing the "Hu" mantra aids the Spleen in transforming and transporting food. One must avoid making audible sounds heard by the mouth or ears; its efficacy surpasses that of Baoshen Dan (Preserve Spirit Pill).

The method of regulating breath penetrates the three teachings (Confucianism, Buddhism, Daoism). On a grand scale, it can lead to Daoist attainment; on a small scale, it can be used for health preservation. It is the highest vehicle among static meditation practices. Thus, Shakyamuni Buddha taught gazing at the white light at the tip of the nose and counting inhalations and exhalations as the initial gate for Zhi-Guan (Calmness and Insight) practice. Zhuangzi's *Nanhua Jing* states: "The breath of the perfected person reaches the heels." The *I Ching*, Hexagram Sui (Following), says: "The superior man enters into rest and repose at dusk." Wang Longxi said: "Ancient perfected persons had breath but no sleep, hence 'entering rest at dusk.'" The method of evening rest should be practiced at dusk: ears hear nothing, eyes see nothing, limbs do not move, and the mind holds no thoughts, like preserving a fire ember. Yuan Jing (Primordial Essence), Yuan Shen (Primordial Spirit), and Yuan Qi (Primordial Qi) nurture each other, with true intention continuous. Laozi's description of "continuous and seemingly existing" refers to this. Its opening and closing are natural, identical to the Void, thus capable of sharing longevity with the Void. People busy themselves all day, their spirit exhausted and ruined, relying on one night's sleep to suffice for daytime use. If one cannot regulate breath, a spark of brightness is entirely obscured by postnatal turbidity, which is called Yang sinking into Yin.

The method of regulating breath is not restricted by time. Sit upright, loosen clothes and belt, ensuring comfort. Stir the tongue in the mouth several times, slightly exhale turbid air without sound, and slightly inhale clear air through the nose, repeating three to five times or fourteen times. Swallow saliva if produced, click teeth several times, place the tongue tip against the upper palate, press lips and teeth together, lower eyelids half-closed creating a hazy state, gradually regulate breath to be neither panting nor coarse. Count either exhalations or inhalations. From one to ten, from ten to a hundred, focus the mind on the numbers, preventing distraction. If mind and breath rely on each other and distracting thoughts cease, stop counting and let nature take its course; sitting longer is more profound. To rise, slowly stretch and relax limbs, do not stand up abruptly. Diligent practice yields various wondrous scenes in stillness, potentially illuminating the mind and revealing nature, not merely preserving the body and life. Inhalations and exhalations are continuous, seeming to exist yet vanish; spirit and qi rely on each other, constituting True Breath. With every breath returning to the root, one naturally seizes the creation of Heaven and Earth, the miraculous Dao of immortality.

Su Shi's *Ode to Health Preservation* states: "Eat only when hungry, stop before full; walk leisurely, ensure the abdomen is empty. When the abdomen is empty, enter the room, regardless of day or night, sit or lie as convenient, focusing on restraining the body. Make it like a wooden puppet, constantly thinking: This body of mine, if it moves even slightly, like a hair's breadth, will fall into hell, just as Shang Yang's laws and Sun Wu's military orders must be executed, preferring death to violation. Also quoting Buddha and Laozi: Gaze at the white light at the nose tip, count breaths, continuous and seemingly existing, use it moderately. Counting to hundreds, this body becomes silent and motionless, equal to the Void, requiring no coercion, naturally immobile. Counting to thousands, or unable to count, there is a method, tentatively named: Following the breath out, then following it in, continuing to follow. Once the breath rests naturally, neither out nor in, suddenly feel the breath distributing from pores like clouds steaming and rain scattering. Since beginningless time, all diseases self-remove, all obstacles self-extinguish, Samadhi generates wisdom, naturally achieving enlightenment. Like a blind person suddenly gaining sight, why seek others to point the way! Thus, the old man's words end here."

Small Microcosmic Orbit Method: First clarify and stabilize mind and body. Face east, sit cross-legged (or flat-sit is acceptable, but front knees must not droop, testicles must not touch objects). Breathing should be peaceful. Form the Samadhi Mudra with hands, pinching the ring finger, right palm over left palm, pressing below the navel. Click teeth thirty-six times to gather mental focus. Perform Chi Long Jiao Hai (Red Dragon Stirring the Sea - tongue stirring inside and outside teeth) thirty-six times total. Chi Long refers to the tongue; inside/outside refers to inside/outside of teeth. Eyes follow the tongue's movement, tongue tip against the upper palate, quietly count breaths. After 360 orbits, wait for Shen Shui (spiritual water/saliva) to fill the mouth, rinse several times, using the Four-Character Mantra: (Lift anus, tongue against upper palate, close eyes look upward, inhale through nose do not exhale). From the Ren Mai (Conception Vessel), lift through the Gu Dao (anus) to the Weilu acupoint, send with intention, slowly ascend to the Ji Ji Middle Pass, gradually speed up, close eyes look upward, inhale through nose do not exhale, crash through the Yuzhen acupoint (bone behind neck/head), hold gaze forward briefly, directly rotate to Kunlun acupoint (top of head), descend via Que Qiao (tongue), divide saliva and send down through Chong Lou (trachea) into Li Gong (Heart), reaching Qi Hai (acupoint below navel). Stabilize slightly, repeat previous method three times, swallow oral saliva in three portions, known as Tian He Shui Ni Liu (Milky Way Water Flowing Upstream). Sit quietly for a moment, rub Dantien left and right one hundred and eight times, embrace navel, upon releasing, wrap clothes around umbilical region to prevent wind entry ("Ancient saying: Nourish Dantien until warm and hot, this is the immortal's true wonderful method"). Next, rub thumb back until warm, rub eyes fourteen times to remove Heart Fire; rub nose thirty-six times to moisten Lungs; rub ears fourteen times to tonify Kidneys; rub face fourteen times to strengthen Spleen. Cover ears with hands to ring Heavenly Drum, slowly raise hands to perform bowing to heaven gesture, repeat three times, slowly exhale turbid air four or five times. Inhale clear air through nose, embrace shoulders with hands, move sinews and bones several times, rub Yuzhen Pass twenty-four times, rub Yao Yan (Kidney Hall) one hundred and eight times, rub Zu Xin (Yongquan acupoint) one hundred and eight times each, constituting one cycle. Practicing this long-term strengthens spirit, prevents all diseases, and promotes longevity and anti-aging.
