Shang Shu (“Classic of History”) is a book of recorded history of China's remote ages. It is the oldest known history book, having recorded history from the remote antiquity of Emperor Yao (2356 – 2255 BC) and Emperor Shun (2294 – 2184 BC), to that of the Shang (1600 – 1046 BC) and Zhou (1046 – 256 BC) Dynasties. From this book, we can see how the ancient people regarded Heaven and man as one, in their words and actions. Below are a few examples.
 
1. Heaven Punishes the Enormities
 
This example is from the chapter "Xibo Kan Li" within the section about the Shang Dynasty. After Duke Wen of Zhou defeated the Li State, Zuyi was very frightened and went to warn King Zhou of Shang, saying:
 
"Your Excellence, I'm afraid that Heaven is going to terminate our Shang Dynasty! Even deities and divine turtles could not perceive any good omen. It is not that our ancestors do not help us, it is because Your Excellency is short in morals and your extravagant and dissipated ways have alienated us from Heaven. That is why Heaven has abandoned us and not allowed us to have grain for food. Your Excellency does not understand the nature of Heaven and does not observe the law. Now all of the people wish to see you perish. They say, 'Why doesn't Heaven deliver mighty punishment?' The Mandate of Heaven is about to be withdrawn. What is Your Excellency going to do?"
 
The chapter “Weizi” recorded minister Weizi’s speech, “The Shang dynasty is likely unable to rule the world. Our ancestor King Tang of Shang formulated the laws at the beginning, but King Zhou intoxicates himself with alcohol and women, tarnishing the name of King Tang. Everyone in the Shang kingdom snatches and steals, breaking the law and causing trouble. The government officials all violate the rule of law…”
 
The first article in Zhou Shu (the history of the Zhou Dynasty) is entitled "Pledge in Muye." It is the pledge King Wu of the Zhou Dynasty made in Muye. King Wu said:
 

"There was a saying in ancient times, 'No hen crows in the morning; if it did, the household would decline.' Now King Zhou of the Shang Dynasty only listens to his women and does not offer sacrifices to his ancestors out of reverence and for blessings. He ignores and abandons his brothers of the same ancestors, but respects, worships, trusts, and employs those criminals at large, appointing them as high-ranking officials in the court, who then treat the people brutally and cause trouble in Shang. Now I, Ji Fa (King Wu’s name), will follow the will of Heaven to punish them."

《尚书》的启示 (上)
 
《尚书》是一部记载中国上古历史的书，是一部最老的历史文献，从尧舜直到商周。从中我们能看到书中记载了很多古人天人合一的言行境界，列举一二。
 
一、天罚无道
 
商书《西伯戡黎》记载：周文王打败了黎国以后，祖伊恐，奔告于纣王。曰：“天子！天既讫我殷命。格人元龟，罔敢知吉。非先王不相我后人，惟王淫戏用自绝。故天弃我，不有康食。不虞天性，不迪率典。今我民罔旨欲丧，曰：‘天曷不除威？’大命不挚，今王其如台？”
 
祖伊意思是说：“天子，天意恐怕要终止我们殷商的国运了！神人和神龟都不能觉察出吉兆。不是先王不扶助我们后人，而是大王淫荡嬉戏自绝于天。所以上天抛弃我们，不让我们得到糟糠之食。大王不揣度天性，不遵循法律。如今百姓没有不希望大王灭亡的，他们说：‘老天为什么不降威罚呢？’天命不再归向我们了，现在大王将要怎么办呢？”
 
《微子》记载了大臣微子的言论：“殷商恐怕不能治理好天下了。我们的先祖成汤制定了常法在先，而纣王沉醉在酒中，因淫乱而败坏成汤的美德在后。殷商的大小臣民无不抢夺偷盗、犯法作乱，官员们都违反法度……”
 
周书第一篇《牧誓》，是周武王在牧野的誓师。王曰：“古人有言曰：‘牝鸡无晨；牝鸡之晨，惟家之索。’今商王受惟妇言是用，昏弃厥肆弗答，昏弃厥遗王父母弟不迪，乃惟四方之多罪逋逃，是崇是长，是信是使，是以为大夫卿士。俾暴虐于百姓，以奸宄于商邑。今予发惟恭谨行天之罚。今日之事，……”
 
武王说：“古人有话说：‘母鸡没有在早晨啼叫的；如果母鸡在早晨啼叫，这个人家就会衰落。’现在商王纣只是听信妇人的话，轻视对祖宗的祭祀不问，轻视并遗弃他的同祖的兄弟不用，竟然只对四方重罪逃亡的人，这样推崇，这样尊敬，这样信任，这样使用，用他们做大夫、卿士的官。使他们残暴对待老百姓，在商国作乱。现在，我姬发奉行老天的惩罚。今天的战事，……”
