Doctrine of the Mean
"Xiudao" () means "practice a religious regimen; follow religious rules; enter a monastery". The first sentence in the Confucian "Doctrine of the Mean" (tr. Legge 1893:124) associates "xiudao" with "jiao" "teach; instruct": "What Heaven has conferred is called The Nature; an accordance with this nature is called The Path of duty; the regulation of this path is called Instruction."
