北魏太平真君七年灭佛的原因可分为直接显明和间接隐晦两大类。在长安一佛寺中发现搜出了大量兵器、酿酒具、财物、淫室。这是刺激太武帝、崔浩等决心完全消灭佛教的四大刺激物，也是使得灭佛理由充分的四大罪证。由于当时盖吴领导的少数民族起义声势浩大，严重威胁到北魏的统治。在这种严峻的形势下发现佛寺藏有大量兵器，自然怀疑沙门与盖吴通谋造反。饮酒酿酒、蓄财窝赃、淫乱好色，这些行径既违反了佛教戒律，又严重触犯了北魏法令。而北魏一贯严刑峻法。加之敛财还扰乱了吏治。淫乱还玷污了鲜卑人的尊严，亵渎了世家大族的高贵，有民族矛盾和士庶冲突的成分。因而这四类罪证构成导致最后灭佛的四大直接原因和理由。 The reason that the Northern Wei Taipingzhen monarch destroyed Buddhism for seven years can be divided into direct and indirect obscure categories. Found in Chang’an Temple a large number of weapons found, wine, wine, prostitution. This is the four stimuli that have stimulated the emperor, Cui Hao and others to completely eliminate Buddhism. They are also the four major evidences that justify the elimination of Buddhism. At that time, the massive ethnic uprising led by Guyana was a massive threat to the rule of the Northern Wei Dynasty. In this grim situation found in a large number of weapons possession of Buddhist temples, natural suspicion Sandou and cover Wu Tong rebel. Drinking wine, making money, making prostitution and pornography both violated Buddhist precepts and severely violated the Northern Wei decree. The Northern Wei Dynasty has always been severely punished. Coupled with the fiscal revenue also disrupted the official. Prodigalism also tarnished the dignity of the Xianbei people, desecrated the noble family members, ethnic conflicts and conflicts between officials and husband. Therefore, these four types of evidence constitute the four direct causes and causes leading to the final elimination of Buddhism.
