从来娶妇必期偕老，生子必望长成，乃人有伉俪极笃，而中道死亡，产育艰难，而
半途夭折者，只因肆情纵欲，暗犯禁忌，而不自知也。道经云∶男女交媾，最有避忌，若
犯所忌，天夺其算，神降之殃，生子丑貌怪相，性行不良，生理残障夭札，实有明验，故君
子不独外色锄之务尽，即房帏之内，琴瑟之欢，俱有克治之道焉。

自古以来，娶妻必定期望白头偕老，生子必定希望长成成人，然而有人夫妻情笃，却中途丧偶；生育艰难，孩子却半途夭折。这仅仅是因为放纵情欲，暗中触犯禁忌，而自己却不知道的缘故。道经说：男女交媾，最讲究避忌，如果触犯所忌，上天会剥夺其寿命，神明降下灾殃，导致子女相貌丑陋怪异，性情品行不良，生理残疾早夭，确实有明确的验证。所以君子不仅在外在禁绝女色务求彻底，即使在房帏之内，琴瑟之欢，也有克制修养的道理。

陈抟说：上等之士不同室，中等之士不同床，下等之士不同被，遵守这些戒期的人，非同室不同床不可。谨按：《礼记·月令》说：日夜平分，雷开始发声。打雷前三天，敲木铎号令百姓。说“雷将发声”，有不节制行为者，生子不健全，必有凶灾。可知禁忌，自古就有。日长至（夏至）时说停止声色，不要进用。日短至（冬至）时说去除声色，禁止嗜欲。大概冬夏二至，是阴阳相争之时，最难保护。前后数日，都宜绝欲。俗话说：乐极生悲，纵欲成患。谨劝世人，须为长久之欢，不要逞一时之乐。欲望浓则短暂，欲望淡则长久，道理不错，事实不虚。凡一切不合时宜之地，能不严格戒除吗？笃信之士，贤德之妇，每逢禁忌，必严格遵守。不仅自身健康强壮，自然能多生好子了。

Since ancient times, when a man marries, he expects to grow old together; when a child is born, he hopes for the child to grow up. Yet there are those with deep marital affection who die midway, or face difficult childbirth only for the child to perish prematurely. This is solely due to indulging in lust, secretly violating taboos, without realizing it. The Daoist scriptures state: Sexual intercourse requires strict avoidance of certain conditions. If these taboos are violated, Heaven will shorten one's lifespan, and deities will bring disaster, resulting in children with ugly or strange appearances, bad temperaments, physical disabilities, or premature death. There is clear evidence for this. Therefore, a gentleman not only strictly avoids external sexual temptations but also practices self-restraint within the bedroom, understanding the principles of managing sexual activity.

Chen Tuan said: Superior scholars sleep in different rooms, medium scholars in different beds, inferior scholars in different covers. Those observing these taboos must sleep in different rooms and beds. According to the *Book of Rites · Monthly Ordinances*: "When day and night are equal, thunder sounds. Three days before thunder, beat the wooden clapper to warn the people. 'Thunder is about to sound.' Those who do not guard their conduct will have imperfect children and surely face disaster." Thus, taboos have existed since ancient times. At the Summer Solstice (Day Lengthens), it says "Stop music and women, do not advance." At the Winter Solstice (Day Shortens), it says "Remove music and women, forbid desires." Generally, the Winter and Summer Solstices are times when Yin and Yang contend, making protection most difficult. Abstinence is advisable for several days before and after. As the saying goes: Extreme joy begets sorrow, indulgence breeds disaster. I earnestly advise the world: Seek long-lasting joy, not momentary pleasure. Intense desire is fleeting; mild desire is lasting. The principle holds true, the facts are not false. For all places and times that are improper, can one not strictly abstain? Devoted believers and virtuous wives, upon encountering taboos, must strictly observe them. Not only will they remain healthy and strong, but they will naturally produce many good children.
