知
病
The disease of knowing
Biết điều không biết là cao. Không biết điều đáng biết là bệnh.
To know and yet (think) we do not know is the highest (attainment); not to know (and yet think) we do know is a disease.
Biết sợ bệnh, thì không bệnh.
It is simply by being pained at (the thought of) having this disease that we are preserved from it.
Thánh nhân không bệnh, vì biết sợ bệnh, thế nên không bệnh.
The sage has not the disease. He knows the pain that would be inseparable from it, and therefore he does not have it.
