夫修身之士,不识丹田所在,咸指脐下一寸三分为言,谬乎!有传此为气禀之原,若果
气于蒂,坎离上下,以此为中宫,气脉升降,以此为根地,根地否塞,则水火不能升降,心
火炎炽,肾水枯竭,百病由此而生。上或头晕眼花,下至腰疼疝凝痔结,甚或真阳不固,多
至夭折,良可悲乎!人诚能以却病延年之法,敬而行之,或行或坐,或立或卧,念念不忘。
日之间,血气循视而不乱,精神内固而不摇,衰者起,萎者愈。疲癃转康健之躯,枯槁回温
润之色,顿觉增精补髓,养气助阳,眼目光明,疝痔消灭,身轻力健,百病咸除,功简而效
速,诚为保身之至道,却病之秘诀哉!
水潮除后患,起火得长安。梦失封金柜,形衰守玉关。鼓呵消积滞,兜礼治伤寒。叩牙
疾,观升鬓不斑。运睛除眼害,掩耳去头旋。托踏应无病,搓涂自驻颜。闭摩通滞气,凝抱
固丹田。淡食能多补,无心得大还。
平时睡醒时,即起端坐,凝神息虑,舌抵上 ,闭口调息,津液自生,分作三次,以意
,此水潮之功也。津既咽下,在心化血,在肝明目,在脾养神,在肺助气,在肾生精,自然
百体调畅,诸病不生,此除后患之功也。逍遥子长生诀曰∶法水潮在关,逍遥日夜还,于中
凝结生诸病,才决通流便驻颜。
Those who devote themselves to self-cultivation, if they do not know the location of the Dantian (Lower Elixir Field), all point to one inch and three fen below the navel as the place, which is erroneous! Some transmit that this is the origin of Qi endowment (innate Yuan Qi). If Qi truly takes root here, Kan (Kidney Water) and Li (Heart Fire) interact above and below, with this serving as the Central Palace (center of the body), the root ground for the ascending and descending of Qi meridians. If this root ground is blocked, then Water and Fire cannot ascend and descend in communication, leading to blazing Heart Fire and depleted Kidney Water, from which myriad diseases arise. Above, there may be dizziness and blurred vision; below, it extends to lower back pain, condensation of hernia, and accumulation of hemorrhoids, or even insecurity of True Yang, leading to premature death, which is truly sorrowful! If people can sincerely employ the method of eliminating disease and prolonging life, practicing it with reverence, whether walking, sitting, standing, or lying down, keeping it constantly in mind. Throughout the day, Blood and Qi circulate orderly without disorder, Spirit remains internally secured without wavering, the weak recover, the emaciated heal. The fatigued and obstructed transform into a healthy physique, the withered color returns to warmth and moisture, suddenly feeling an increase in Essence and replenishment of Marrow, nourishing Qi and assisting Yang, eyes becoming bright, hernias and hemorrhoids disappearing, the body becoming light and strength robust, all diseases completely eliminated. The effort is simple and the effect rapid; this is indeed the supreme way to preserve the body and the secret to eliminating disease!
"Water Tide" eliminates subsequent troubles; "Fire Rising" obtains long-term peace. Dream loss (nocturnal emission) is sealed like a golden cabinet; when the form declines, guard the Jade Gate (referring to the lower Yuan essence). Drumming and blowing eliminate stagnation;兜礼 (a specific Qigong movement) treats Taiyang syndrome (Cold Damage). Clicking teeth cures dental ailments; observing rising things prevents graying of temples. Moving eyes removes ocular harm; covering ears dispels vertigo. Lifting and treading ensures freedom from illness; rubbing and applying naturally preserves youth. Closing and massifying unblocks stagnant Qi; concentrating and embracing solidifies the Dantian. Light diet can provide abundant nourishment; having no mind (non-attachment) achieves the Great Return (Great Elixir).
When waking up normally, immediately rise and sit upright, concentrate the spirit, calm thoughts, press the tongue against the upper palate, close the mouth and regulate breathing, saliva generates naturally, divide into three swallows, guide downward with intention; this is the merit of "Water Tide". Once the saliva is swallowed, in the Heart it transforms into Blood, in the Liver it brightens the eyes, in the Spleen it nourishes Shen (Spirit), in the Lung it assists Qi, in the Kidney it generates Essence, naturally making all limbs harmonious and various diseases not arising; this is the merit of "eliminating subsequent troubles". The Longevity Manual of Xiaoyaozi says: "The method of Water Tide is at the Guan (Gate), Xiaoyao returns day and night, condensation within generates various diseases, once flow is released, youth is preserved."
