问∶修炼待时,然后下手?答曰∶有时中之工夫,有刻中之工夫。毗陵曰∶炼丹不用寻冬至,心
中自有一阳生。马自然曰∶不择时中分子午,无爻卦内别乾坤。此皆刻中之工
夫也。
问∶金丹形象如何?答曰∶形若弹丸,色同朱桔。抱朴子曰∶大如弹丸黄如桔,中有佳味甘如蜜。
沙门得之即禅定,黄衣得之即超逸,审之行之天地毕。《元枢歌》曰∶君不见,一粒金丹何赫赫,大如弹
子黄如桔。人人分上本圆成,夜夜灵光长满室。盖人人具足,个个圆成。当知非有形之物也,吕公曰∶
还丹本质也。
问∶玄关一窍,正在何处?答曰∶在人之首。功夫容易见,下手的难寻。若不遇真师摩顶授记,
皆妄为矣。
问∶真空?答曰∶返本还元为真空。杏林曰∶不知丹诀妙,终日玩真空。
问∶作用?答曰∶螟蛉咒子,传精送神。
问∶出神?答曰∶能守真一,真气自凝,阳神自聚。盖以一心运诸气,气住则神住。真积力久
功行满,然后调神出壳也。
问∶超脱?答曰∶超者,出也。脱者,换凡躯也。皆天门出。前圣有脱壳之验∶六祖七层宝
塔出,钟吕七级红楼出,海蟾公鹤冲天门出。诗曰∶功成须是出神京,内院繁华勿累身。会取五仙
超脱法,炼成仙质离凡尘。
Question: Does cultivation require waiting for a specific time before applying effort? Answer: There is the work of "Shi Zhong" (timely appropriateness), and there is the work of "Ke Zhong" (momentary appropriateness). Piling said: "To refine the elixir, one need not seek the Winter Solstice; within the mind, Yang Qi naturally arises." Ma Ziran said: "Do not select Zi and Wu hours in time; within the hexagrams, distinguish Qian and Kun (Heaven and Earth/Yang and Yin)." These are all works of Ke Zhong.
Question: What is the appearance of the Golden Elixir? Answer: Its shape is like a bullet, its color is like a vermilion tangerine. Baopuzi said: "Large as a bullet, yellow as a tangerine, within lies a fine taste, sweet as honey." A monk who obtains it enters Samadhi (meditative absorption); a Daoist priest who obtains it achieves transcendence; carefully contemplating and practicing it allows one to exhaust the principles of Heaven and Earth. The *Yuanshu Ge* says: "Have you not seen how magnificent a single grain of Golden Elixir is, large as a bullet, yellow as a tangerine. Everyone's nature is originally complete; every night spiritual light fills the room. Essentially, everyone possesses it fully, everyone is originally perfect. One must know it is not a tangible object." Master Lü said: "The Returning Elixir is its essence."
Question: Where exactly is the Mysterious Pass Single Aperture located? Answer: It is in the human head. The work is easy to perceive, but the point of application is difficult to find. Without meeting a true master to anoint the crown and transmit the secret, all efforts are futile.
Question: What is True Emptiness? Answer: Returning to the root and restoring the origin is True Emptiness. Xinglin said: "If one does not know the subtlety of the Elixir formula, one spends the whole day playing with 'True Emptiness'."
Question: What is its function? Answer: Like the silkworm moth adopting larvae (a metaphor for transformation), using mantras to protect the offspring, transmitting Jing (Essence) and nurturing Shen (Spirit).
Question: What is the emergence of Spirit? Answer: If one can guard the True One (the primordial unity), True Qi will naturally condense, and Yang Shen (Spirit) will naturally gather. Generally, by using one mind to direct various Qi, when Qi rests, Spirit rests. After accumulation of truth and long-lasting effort, when merit and conduct are complete, then the Spirit is guided out of the shell (body).
Question: What is Transcendence? Answer: "Chao" means to exit; "Tuo" means to shed the mortal body. All exit through the Heavenly Gate (the aperture at the top of the head). Ancient sages have verified examples of shedding the shell: The Sixth Patriarch emerged from a seven-story pagoda; Zhongli Quan and Lü Dongbin emerged from a seven-level red tower; Liu Haichan rode a crane to burst through the Heavenly Gate. The poem states: "Upon completion of merit, one must exit the capital (metaphor for the mundane world or physical limitation); do not let the prosperity of the inner courtyard burden the self. Comprehend the method of the Five Immortals' transcendence, refine into an immortal nature to leave the mortal dust."
