Learn it extensively, interrogate it, think carefully, discern it clearly, and practice it diligently. ——"Book of Rites· Doctrine of the Mean"

Learning without thinking will lead to confusion, thinking without learning will lead to peril.

When three people walk together, there must be a teacher from me

The ancient scholars must have a teacher. A teacher is the one who preaches the truth, receives karma and resolves doubts. People are not born with knowledge, how can they be free from confusion? If you are confused and do not follow the teacher, it is confusion, and you will never be able to understand it.
