What is the relationship between Sanqing Daozun?

Chapter 42 of the Tao Te Ching says, "The Tao gives birth to one, two, three and three things, and all things are negative and embrace Yang, and they rush to think of peace." From nameless avenue to chaotic vitality, from vitality to yin and yang, yin and yang combine to create everything. Chapter 14 also says: "If you don't look at the name, you are called a foreigner; If you listen, you will call it hope; If you don't fight, it's called micro. These three can't be blamed, so they are mixed into one. " I think one is three and three is one. ""divided into three, this is always one. "Later, Taoism derived three gods. Therefore, the "Sanqing" god is the most respected in the Taoist immortal system. In the seventh volume of Daoism, Taizhenke was quoted as saying: "Rhoda gave birth to the third day of Xuanyuan, and turned it into a three-clear heaven: a clear sky in Wan Li, from the beginning; The next day, Yu Yu went to the Qing Dynasty. The third is that the sky is too clear and the atmosphere is mysterious. Since then, three gases have been born. "

According to Taoist books such as "The Seven Chapters of the Cloud" and "The Taoist Hui Yuan", the sky is clear and clear, and the mixed points are too empty, and its qi begins to be green, and the true Tao rises to the sacred land, and Tianbao Zun (Yuan Shi Tian Zun) governs; Yu Yu entered the Qing Dynasty in the rest of the day, and his qi was yellow, and Xianlu rose to the true state, and Lingbao respected it; The sky is too clear and the gas is white; Humanity rose to a fairyland, where Taoism lived. Wen said: "These four kinds of people and heaven are above the three realms, so it is better to have three realms between them. Above Sanqing is Daluotian, where the Buddha lived and gave lectures in the Yuan Dynasty. Tianbao Junzhi is in the realm of jade Qing, and the sky is high and the clouds are light. Lingbaojun aims to be clear, that is, fish and rain are wild, and Shenbaozun (moral Buddha) is clear, that is, holding Amano. "

("Seven Years Cloud" Volume III, "The Beginning of Taoism") According to the cloud "Reading the Classics", "Sanqing lived in the Holy Land of Jade Qing and began to live in the Yuan Dynasty; Qing sacred land, Daojun lived there; Taiqing fairyland, where the old gentleman lives. " At the same time, Taoism's worship of Sanqing gods also embodies the deification of Taoism's "Three Caves True Classics". "The Seven Chapters of Clouds", volume six or three holes, says: "On the gate, those who have three holes in the cloud are called holes. Xuan Tong is great. There are three systems, so there are three holes in the cloud. The first hole is real, the second hole is mysterious, and the third hole is god. It is the mysterious purpose of the three games and the spiritual chapter of the eight major. "

According to the record of "Wei Qing's Divine Position in Wei Qing Road and Law Hub", "Road and Law Huiyuan" Volume 1; At the beginning of Yuan Dynasty, the sage represented the eastern part of Miao Dao, assisted Taixuan and spread Wei Qing School. Wei Qing Xuanzu hired Dadaojun in Qingling Fuyu, representing Dong Xuanjing's department, supplemented by Taiping, and inheriting Lingbao School; Xuanlaojun, the ancestor of the Five Spirits of Taiqing Morality, represents Dong's nervous system, supplemented by Taiqing, and the way of "one alliance and one prestige" runs through the three caves, spreading morality and orthodoxy.
