又况终日奔驰，无时休息，当夜后汤濯二足，此之益而少矣。不若高举二足，使气倒行，
流于涌泉，逆流于丹田，积日足轻，行及奔马，其步如飞矣。昔人以四肢小疾，五脏微 ，
气血凝滞壅塞，静坐澄心，闭目绝念，运心气于所病之处，暂息少时，无攻不胜矣。昔人
以五脏积滞，用六字气治之，即黄廷图之法也。张正道以此留形住世，王悟真以此治病延
年，孙思邈以此修身治人。六字之法者，春不呼，夏不 ，冬不呵，秋不吁，四时常唏，
谓三焦无不足，八节不得吹，谓肾脏难得实。凡有余则引其子，不足则杀其鬼。此
法方今无知者，西山上圣得其咏也。不须禁忌，但朝不食虚，暮不食实，上也，素无味，
淡无荤，次也，何虑四体之不充悦乎。及夫六字气有余引子、不足杀鬼者，肝本呼也，
余则用呼，呼亦不能引肝气，若引子气，则用 字，泻心之气，心气既行，肝气自传也。
Moreover, if one runs about all day without rest, and only soaks the two feet in hot water at night, the benefit derived from this is minimal. It is better to raise the two feet high, causing Qi to reverse its flow, flowing into Yongquan (KI 1), and counter-flowing into the Dantian. After accumulating days, the feet become light, walking speed can rival a galloping horse, and steps are like flying. In the past, people used stillness to clarify the mind for minor ailments of the four limbs, slight disorders of the five Zang organs, and stagnation or obstruction of Qi and Blood. By sitting quietly, clearing the mind, closing the eyes, cutting off thoughts, and directing Heart Qi to the diseased area for a short while, there was no condition that could not be overcome. In the past, people treated accumulations and stagnations in the five Zang organs using the Six Syllable Breath method, which is the method of Huang Tingtuo. Zhang Zhengdao used this to preserve his form and prolong his life; Wang Wuzhen used this to treat diseases and extend longevity; Sun Simiao used this to cultivate himself and treat others. The method of the Six Syllables states: do not exhale with "Hu" in Spring, do not exhale with "He" in Summer, do not exhale with "He" in Winter, do not exhale with "Xu" in Autumn, and always sigh with "Xi" in the Four Seasons. This means the San Jiao (Triple Burner) has no deficiency; do not blow with "Chui" during the Eight Solar Terms, meaning the Kidney rarely achieves fullness. Whenever there is excess, draw out its Child element; whenever there is deficiency, suppress its Ghost (overcoming) element. This method is currently unknown to anyone; the Sages on Western Mountain have received its chants. No taboos are needed, but it is best to not eat empty/deficient foods in the morning and solid/rich foods in the evening; second best is plain food without flavor and vegetarian diet without meat. Why worry about the limbs and body not being filled and joyful? Regarding the principle of the Six Syllable Breath where excess draws the Child and deficiency kills the Ghost: the Liver's native breath is "Hu". If "Hu" cannot draw out Liver Qi, to draw the Child Qi, use the "Si" syllable to drain Heart Qi. Once Heart Qi moves, Liver Qi naturally transmits.
