How did the tang use buddhism to rule, and what was its impact on chinese society?

Buddhism was essentially a foreign religion in a culture with many well-established philosophical and religious traditions, notably Taoism and Confucianism. These three belief systems coexisted to varying degrees during both the Tang and Song dynasties. Confucianism guided the social realm— governance, education, family life, relationships among levels of society. It provided ethical guidelines for maintaining social order. Taoism offered mystical, proto-scientific ideas about one’s health, well-being, procreation, and longevity. In the Chinese context, Buddhism dealt mainly with the afterlife, the effects of good and bad deeds; addressing life’s misfortunes; it also promised release from suffering.

By the Tang dynasty, Buddhist temples and shrines had spread across the country. Buddhism enjoyed a great deal of state support. Then as now, lay people made donations to monks and temples to secure earthly and spiritual rewards. More specifically, they could accrue merit (positive actions resulting in spiritual and practical benefits) through charity, the support of public works (such as refurbishing a local temple), the donation of property, or the commissioning of artworks (a statue, or cave shrine, or production of a set of Buddhist texts). Individuals entering monastic life as monks or nuns still aroused suspicion from some members of society, particularly strict adherents of Confucianism. Sacrificing one’s family name, the possibility of offspring, cutting of one’s hair (a defilement of the body), and embracing poverty ran counter to many time-honored Chinese beliefs.

In a Buddhist context, grand celebrations were often held in honor of rulers, on festival days, in honor of new public works, and to protect the nation from famine or invasion. Some festivals involving the parade of sacred relics were criticized by various members of the court, in particular for arousing hysteria and for lavish expenditures. Buddhism was severely persecuted in 845 and again in the 900s during the Five Dynasties period between the Tang and the Song. Many of the reasons for this suppression were economic. Thousands of temples were destroyed and metal objects melted down for hard currency. Many monks and nuns were forced to return to lay life, where they could contribute to the general tax base.
