Paichangchingkuei(百丈淸規) (regulations for monastic life), made by Paichang Huaihai(百丈懷海 749～814) in the Chinese Tang Dynasty, not only innovated the existing Buddhist association, but also presented new directions for the Chinese Buddhism. Its creativeness and innovative contents had significant meaning in the Chinese Zen sect history, affecting the monastic regulations and the temple structure of the buddhist monastic community, and life in temples where Zazen is simply pursued. In particular, the Meditative School's Regulations and Rituals(禪門規式)containing the spirit of Paichangchingkuei brought about lot of changes in the structure of a Buddhist temple of the Zen sect as it says “Build not the hall where the image of Buddha and Buddhisattvas are enshrined, but the lecture hall.” In the Buddhist community, the establishment of the regulations presented a chance to create a new Zen sect which pursued Zazen in a general temple. It also changed the existing types and roles of a Buddhist temple. The Chinese Zen sect took finally its roots in the Tang Dynasty, heralding the era of Shenhui's(神秀) Northern sect meditation(北宗禪) and Huineng's(慧能) Southern sect meditation(南宗禪). Southern sect meditator and northern sect meditator showed a big difference in terms of the type of a Buddhist temple where they stayed. Southern sect meditator mainly built a new temple to live in while northern sect meditator stayed in the existing temples. After Paichang established the regulations for monastic life, there were a lot of innovative changes in the role of a Buddhist temple. Paichang tried to change the role of a Buddhist temple from the place to focus on the courtesy for the nation and the Emperor with the hall where the image of Buddha and Buddhisattvas were enshrined at the center to the place to focus on practice pursued according to the Buddha's precepts by building the lecture hall. In conclusion, making the regulations presented various meanings to the Buddhist Community as followed： First, it plays a part in establishing the Zen sect as a sect. And also, as temples where Zazen is simply pursued were separated from the general temples, they had the power to control and govern the Zen sect on its own. Second, Meditative School's Regulations and Rituals(禪門規式) which says “Build not the hall where the image of Buddha and Buddhisattvas are enshrined, but the lecture hall”, had significant effects on the structure of a Zen sect temple in the Tang Dynasty. While northern sect meditator depending on outside helper(外護者 )stayed and did practice pursued according to the Buddha's precepts in the existing temples and Southern sect meditator built a temple to practise in, the construction of a Zen sect temple afterwards had the tendency to rely on Dannas(donors who always contribute to a temple). Such development and changes in a Zen sect temple caused significant changes in the history of the Zen sect. The Meditative School's Regulations and Rituals(禪門規式) tried to change the role of a Buddhist temple from courtesy for the Imperial household and the nation to practise of the Buddha's precepts as mentioned above. The change of the role can be seen as an effort to effectively rule the Buddhist Community by operating a temple through selfsufficiency by a temple to caution against the tendency of a temple relying too much on Dannas. Paichang's spirit of the regulations had been observed for almost half a century. Since then, however, as a Buddhist temple economically depended on Dannas, the entire monastery was deteriorated and Paichang's spirit was lost. At the same time, the functions of the Buddha's hall has been changed.
