取赤谷子熟时绞汁，煎如稠饧，可用和丹砂。如无谷子，谷皮亦得。凡服丹砂，忌一切
鱼肉尘宿生冷蒜，尤忌生血物，及见血秽。江阴葛侍郎，中年病足几废，久治不瘥，得此服
遂愈。而轻健过于少时，年八十余，饮啖视听不衰，宝此方未尝传人。予治平中，感足疾，
万端求得之，然游宦竟今，未曾得为之。又太医孙用和，亦尝得此方。仁宗时表献之，其大
概虽相似。然甚粗略，非真方也。
洛下有洞穴，深不可测。有人堕其中不能出，饥甚。见龟蛇无数，每旦辄引首东望，吸
初日光咽之。其人亦随所向效之不已，遂不复饥，身轻力强，后卒还家。不食，不知其所终，
此晋武帝时事，辟谷之法以百数，此为上妙。法止于此，能复玉泉。使铅汞具体，去仙不远
矣。此法甚易知易行，天下莫不能知。知者莫能行，何则？虚一而静者，世无有也。元符二
年，儋耳米贵，吾乃有绝粮之忧。欲与过子共行此法，故书以授之。四月十九日记。
冬至后斋居，常吸鼻液漱炼令甘，乃咽下丹田。以三十瓷器皆有盖，溺其中已，随手盖
之。书识其上，自一至三十。置净室，选谨朴者守之。满三十日开视，其上当结细砂，如浮
蚁状，或黄或赤。密绢帕滤，取新汲水，净淘澄无数，以秽气尽为度，净瓷瓶合贮之。夏至
后，取细研枣肉，丸如梧桐子大。空心酒吞下，不限丸数，三五日后取尽。夏至后仍依前法
采取，却候冬至后服。此名阳丹阴炼。须清净绝欲，若不绝欲，真砂不结。
取成熟时的赤谷子，绞取其汁液，煎煮至像浓糖浆一样稠厚，就可以用来调和丹砂。如果没有赤谷子，用谷皮也可以。凡是服用丹砂的人，禁忌食用一切鱼肉、隔宿的食物、生冷食物以及大蒜，尤其忌讳生血类食物，以及接触见血污秽之物。江阴的葛侍郎，中年时患足疾几乎导致残疾，久治不愈，得到此方服用后便痊愈了。而且身体轻便矫健胜过年轻时，八十多岁时，饮食和视听功能都没有衰退，他珍视这个方子从未传给别人。我在治平年间，染上足疾，费尽心机求得此方，然而因为仕途奔波，至今未曾有机会制作服用。另外太医孙用和，也曾得到过这个方子。在仁宗时期曾上表进献，其大致情况虽然相似，但是非常粗略，不是真正的方剂。
洛阳有洞穴，深不可测。有人掉入其中无法出来，饥饿难耐。看见无数龟蛇，每天早晨都伸长头向东望，吸食初升太阳的光芒并吞咽下去。那个人也跟随它们效仿这种方法不停止，于是就不再感到饥饿，身体轻盈力气增强，后来最终回到了家。不吃东西，不知道他的最终结局，这是晋武帝时期的事情，辟谷的方法数以百计，这是上等的妙法。方法只到这里，如果能再修炼“玉泉”之法，使铅汞凝结成实体，距离成仙就不远了。这种方法很容易知晓也容易实行，天下没有人不能知道。但知道的人却不能实行，为什么呢？因为世间没有能做到虚静专一的人。元符二年，儋耳地区米价昂贵，我有了断粮的忧虑。想要与过子共同实行这种方法，所以记录下来传授给他。四月十九日记录。
冬至之后斋戒居住，经常吸入鼻腔分泌的津液漱口炼化使其变甘甜，然后咽下送入下丹田。准备三十个带盖的瓷器，在其中溺尿，随即随手盖上盖子。在上面书写标记，从一到三十编号。放置在洁净的房间，选择谨慎朴实的人看守。满三十天后打开查看，上面应当结成细沙，像浮蚁的样子，颜色或黄或红。用密绢帕过滤，取新汲取的水，反复淘洗澄清直到没有秽气为止，用干净的瓷瓶密封储存。夏至之后，取细细研磨的枣肉，制成梧桐子大小的药丸。空腹用酒送服，不限丸数，三到五天内服完。夏至之后仍然依照前面的方法采集制备，却等到冬至之后服用。这名叫阳丹阴炼。必须清净断绝欲望，如果不切断欲望，真砂就不会凝结。
Extract the juice from ripe red millet seeds (Setaria italica), decoct it until it is as thick as dense maltose syrup, and then use it to mix with cinnabar. If red millet seeds are unavailable, millet husks may also be used. Whenever taking cinnabar, one must avoid all meat, fish, leftover food, raw and cold foods, and garlic; especially avoid raw blood products and contact with bloody filth. Ge, a Vice Minister from Jiangyin, suffered from a foot disease in middle age that nearly disabled him. After long-term treatment without improvement, he obtained this prescription and took it, resulting in a cure. His body became lighter and more agile than in his youth, and at over eighty years old, his appetite and hearing and vision remained unimpaired. He treasured this prescription and never passed it on to others. During the Zhiping era, I contracted a foot ailment and sought this prescription through various means, but due to my official travels, I have not yet had the opportunity to prepare and take it. Additionally, Sun Yonghe, a Grand Physician, once obtained this prescription. During the reign of Emperor Renzong, he presented it to the court. Although its general outline was similar, it was very crude and not the true prescription.
There is a cave in Luoyang whose depth cannot be measured. A person fell into it and could not get out, suffering from extreme hunger. He saw countless turtles and snakes, each morning stretching their heads eastward to gaze at the sun, inhaling the light of the rising sun and swallowing it. The man followed their example and continued doing so, eventually no longer feeling hungry. His body became light and strong, and he later returned home. He did not eat, and his final fate is unknown. This occurred during the time of Emperor Wu of Jin. There are hundreds of methods for Bigu (fasting/grain avoidance), but this is the finest and most excellent method. With this method alone, if one can also cultivate "Jade Spring" (saliva swallowing practice) and make lead and mercury manifest physically, one will not be far from becoming an immortal. This method is very easy to understand and practice; everyone in the world can know it. However, those who know it cannot practice it. Why? Because there is no one in the world who can achieve emptiness, unity, and stillness. In the second year of Yuanfu, rice prices were high in Dan'er, and I faced the worry of running out of food. I wished to practice this method together with Guozi, so I wrote it down to teach him. Recorded on April 19th.
After the Winter Solstice, reside in abstinence. Frequently inhale nasal mucus, rinse the mouth with it, refine it until it tastes sweet, and then swallow it down to the Lower Dantian (lower abdomen energy center). Prepare thirty porcelain jars with lids. Urinate into them, and immediately cover them. Mark them on top with numbers from one to thirty. Place them in a clean room and select a cautious and simple person to guard them. After thirty days, open and inspect them. Fine sand should form on the surface, resembling floating ants, either yellow or red. Filter through fine silk gauze. Take newly drawn water, wash and clarify repeatedly until all foul odors are gone. Store in a clean porcelain bottle with a tight seal. After the Summer Solstice, take finely ground jujube flesh, form pills the size of sophora tree seeds. Swallow with wine on an empty stomach. The number of pills is unlimited, but finish them within three to five days. After the Summer Solstice, collect and prepare again using the previous method, but wait until after the Winter Solstice to take them. This is called "Yang Cinnabar refined by Yin." One must maintain purity and abstain from sexual desire; if desire is not cut off, true cinnabar will not condense.
