"The challenge is to make the invisible visible."

The soul is the master of the body， not the slave.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

We are all in the gutter, but some of us are looking at the stars.

心灵不是一个静态的实体，而是一个持续调整的动态过程。
