I want to copy scriptures every day. What does it mean that people copy a product every day?

The Sanskrit says, "Pricking blood is ink, marrow is water, bone is analyzed as a pen, and Buddhist precepts are written." There are also sixteen clouds in The Great Wisdom: "If you really love Buddhism, you should take skin as paper, bone as a pen and blood as a book." There are many steps and stresses in writing classics by pricking blood, which have been discussed by predecessors. See: A few years ago, the ancient books of Shandong Library were moved from Daming Lake Branch to Jinan Second Ring Road New Library. In the process of sorting out books, I found a Buddhist sutra written by pricking blood, which appeared in newspapers and became a topic of discussion for a while. In fact, this book has been collected on the second floor of Kuixu Library in Daming Lake for a long time, and it is not a new discovery. In the 1970s, a nationwide survey of ancient books was conducted and a bibliography of rare Chinese ancient books was edited. At that time, for some reason, it was not included in the bibliography of rare Chinese ancient books, but this Buddhist scripture is indeed an extremely precious document. Buddhism emphasizes the merits of reading and writing scriptures. I highly admire the classic as a magic weapon in the three treasures, and I pray for people or seek liberation by writing classics, so I have a strict attitude when writing classics. Most people write scriptures with ink, and some people write scriptures with gold and silver mud. Writing scriptures by pricking blood is the highest form for people to support Buddhist scriptures. The Sanskrit says, "Pricking blood is ink, marrow is water, bone is analyzed as a pen, and Buddhist precepts are written." There are also sixteen clouds in The Great Wisdom: "If you really love Buddhism, you should take skin as paper, bone as a pen and blood as a book." There are many steps and stresses in writing classics by pricking blood, which have been discussed by predecessors. First of all, ancient people only pricked blood from above the heart, or from the tongue or fingers, or from the arms or chest. Write classics by pricking blood, some by pure blood, and some by alloy ink. If you write with pure blood, put it in a clean vessel, first stir it in the blood with a long needle to remove the blood tendons, so that the blood will not stick to the pen and the writing will be smooth. In case of blood coagulation, ginger can be ground before use. When pricking blood, don't stab too much at once. Because the collected blood will stink after a long time, it can no longer be used for writing. If you use arm blood, you can pick up half a bowl at most after stabbing. If it can't dry, use it after grinding with water, or make blood tablets with blood, cinnabar and glue, and use them after drying. Secondly, before pricking blood, you must eat light food and reduce the intake of salt and aniseed. If you don't give up eating these things first, your veins and meridians will gradually turn black, and the words you keep will be light golden yellow. Third, about using paper. The blood is weak, the paper is scattered, and there is no pen and ink, forming a blood cell. This paper must be treated with alum before it can be used. Alum paper is impervious to water and saves blood the most. There are some in the big paper shop, so you don't need to make them yourself. In addition, when writing, it is not recommended to write in regular script and cursive script. As far as content is concerned, the most extant is Huayan Sutra, followed by Heart Sutra and Diamond Sutra. Pricking blood to write scriptures is a long-term and arduous project of eminent monks in past dynasties. It takes several years to cross or write hundreds of words a day, and it is a hard journey of life belief. In the envelope of the blood-pricking book of Huayan Jing in Shandong Provincial Library, a Buddhist disciple said, "This Mahayana magic weapon is the blood-pricking book of Shaman Master Shen Zhan, the heir of the Siming Dynasty in Kangxi period. Yan Guangnan, a disciple of Sakyamuni, made meritorious service in Daoguang for fifteen years. It is estimated that when the stall owner was selling it, Pan Jushi of Cheng 'an Capital was sent to the abbot of Yulu Zen Forest for offering. I hope that monks who read Taoism after me will cherish protection, live forever and spread magic weapons. I only hope that everyone will enter the Peluhai and go to the Xuanmen in China and Tibet. " This paper briefly explains the author and spread of this Huayan Jing. As for when it was collected by the Shandong Provincial Library, there is no textual research. It is worth noting that, judging from the handwriting, Hua Yan Jing has obvious traces of pen drawing. Touched by hand, the word marks are clear and concave. Instead of writing directly with a brush, it may be that the characters are first pressed on the rice paper with a wooden block for printing books, and then filled out with blood. The font is neat, handsome and meticulous. Although it has experienced more than 300 years of vicissitudes, it is still clear, revealing the writer's piety and persistence between the lines. There is a woodcut version of Sakyamuni's statement in front of each book, which is very beautiful. At that time, it was very popular for people to write scriptures and pray for blessings. I guess when the temple sells incense sticks, it also prints some classic block-printed books that are not stained with ink, and sells them to monks and believers who make vows to write scriptures for them to describe and write. In some famous ancient temples in China, there are also Buddhist scriptures written by pricking blood. For example, Zhuang Jie Fa Hui in Xiyuan, Suzhou, Jiangsu, now has a Hua Yan Jing written by Shanji in Yuan Dynasty, which has been written for more than 20 years. The Hua Yan Jing is in the Jiuhuashan History Museum in Anhui Province, which was copied by the flawless Zen master in Ming Dynasty after 28 years. In Yunju Temple in Beijing, there are seven volumes of Tongue Blood and Huayan Sutra written by Zuhui, a eminent monk in the Chongzhen period of Ming Dynasty (A.D. 1628). The Lushan Museum in Jiangxi Province collects the Huayan Sutra copied by Puchao monk in Haihui Temple with blood. He lasted 15 years and died of excessive blood loss at the age of 45. Kaiyuan Temple in Chaozhou, Guangdong Province now has Hua Yan Jing written by Master Zhicheng. In Yongquan Temple in Fuzhou, Fujian, there are still 657 volumes of Mahayana Prajna Paramita Sutra.
