Emperor Wu of the Northern Zhou initially believed in the Buddhist Dharma, but later heeded the slanders of the Daoist Zhang Bin and the apostate monk Wei Yuansong, preparing to abolish the Buddhist teaching. Master Dao'an wrote the Erjiao lun to contest it, stating: 'The teachings of the Nine Schools restrain only the body; they are called outer teachings. The teachings of the Three Vehicles tranquilize the mind; they are called inner teachings. Laozi is not the founder of a religion; he is subsumed under the humility of the Changes.' When the Emperor heard this, finding the rationale for retaining or abolishing them contradictory, he abolished both teachings. In less than five years, he died and the dynasty passed to the Sui. When Emperor Yang succeeded to the throne, he reformed the institutions of the preceding dynasty. Although he ordered homage to be rendered, the monks ultimately did not submit.
