Although Buddhism began in India, it gradually transferred to China in the 200's. There, it was met by mixed reviews in all classes. Some dynasties preferred its philosophy and promise of afterlife to the rigid Confucian ideals that were previously imposed although the Chinese turned to Buddhism for it promises of eternal enlightenment during times of hardship and invasion, the period that followed led to many attempts to reconcile the religion with the traditional Confucianism, increasing many views that Buddhism was a barbaric foreign invasion. The period that followed the Han dynasty was known as the Warring States period, during which China suffered frequent invasions from Central Asia. The documents of "Four Noble Truths" (Doc 1) and Zhi Dun (Doc 2) demonstrate the initial compatibility of Buddhism with the time period. The Buddhist sermon outlines the many steps in the path of stopping all misery, and the Dun document demonstrates the Chinese peoples' embracing this form of salvation as a response to putting control in their own hands. If they couldn't control the nomadic invaders, at least they could follow many rituals with the promise of release from the material world. However, the sermon preached by Buddha was meant for a large audience - so it had to have mass appeal - especially toward the lower castes, in order to reconcile them with their suffering (Doc 1). The Dun document was a political statement with the purpose to convey to the people and sense of sanctuary. Being from the point of view of an upper class scholar, it does not reflect the number of Chinese who actually accepted the Buddhist doctrine. As time continued, outside stresses to the Chinese decreased - and an increasing conflict between Confucianism and Buddhism arose. The "Disposition of Error" (Doc 3) and the "Zong Mi essay" (Doc 5) illustrate attempts to allow both to co-exist.
