In Taihe Period under the rule of Xiaoming Emperor of the last Wei Dynasty, the Master Bodhidharma left Liang Empire moving to Wei and settling in Shao Lin Temple facing the wall for meditation, mortification and searching Dhyana. One day, he told his prentices, "You tell me all what you know and how much you understand the Buddhist doctrine. Let me know your achievement." By the way, all the prentices told the Master the progress of each one by one, and then the master said, "This person has gained my skin; another, muscle; that one, bone. Only Huike gains my marrow." The descendants explained what Bodhidharma said in a simply way had been expressing the different levels of meditation process with his prentices in metaphorical way. But in fact, it was not in figuration but the literate meaning. Bodhidharma underwent suffering and mortified for nine years, he came to nirvana. His body was initially buried at the foot of the Xionger hill but vanished at last. There was only one straw sandal left. The wall Bodhidharma faced for nine years with a legacy were broken down by continual strong wind and raining. The Shao Lin monks found an iron box possibly with a letter inside when they repaired the house. They tried their best to open it but in vain even though it was not locked. One monk suddenly got to understand the box of letter was stuck together by wax. When he put the iron box in fire, the wax fell off and the box was opened. After that, he got two books, one was Xi Sui Jing, i.e. a book named Scripture for Cleaning Marrow, the other was Yi Jin Jing

The introduction of volume One
The main idea of the master Bodhidharma: there are two elemental steps to gain "Zhengguo",called "Chuji", one is "Qingxu", the other is "Tuohuan". To achieve Qingxu, one has to have no any confusion in his feeling and spirit; to achieve Tuohuan, he or she will have got no obstacle, so he can be samadhi (enter into trance). Knowing this, one is said to have got the foundation of work. Qingxu is the same as Xisui; the Tuohuan is the same as Yijing. The idea of Xisui is: through the whole life, a human being always undergoes love and passion. If he cannot resist on refusing all the temptation for his life, he will fail and degenerate. If he wants to gain the Prajna and the gnosis, he must first purely purify his all organs and bones. Only by doing this, can he begin his lesson of mortification and reach the Prajna at last. Without this process of the entry, one is said to have no foundation. To obtain Xisui is to clean one's inside feeling and spirit; the aim of Yi Jing is to strengthen and enhance one's body. If one can both be Qingxu inside and strong outside, it will be easy for him to reach the state of the door of Shen?. The idea ofYi Jin Jing
