Equal efforts need to be exerted to the enhancement of understanding and practice. The clearer your understanding, the more solid your practice is; subsequently, your understanding will become even more clear. Neither one can be done without the other.
Just like two alternating footings, eventually you will reach your goal; should the momentum of one side weaken,
there will be no progress at all.
You must first attain understanding before you can practice.
For this reason, in the Great Learning, the attainment of understanding is mentioned first. In the Doctrine of the Mean, understanding is placed before benevolence and courage.
Confucius stressed that “once understanding is sufficient to attain,” knowledge, careful reflection, clear discrimination, and earnest practice will all be complete.
