Sincerity does not only complete the self; it is the means by which all things are completed. As the self is completed, there is human-heartedness; as things are completed, there is wisdom. This is the virtue of one’s character, and the Way of joining the internal and external. Thus, when we use this, everything is correct.

It is said that what is called "the spirit of an age" is something to which one cannot return. That this spirit gradually dissipates is due to the world's coming to an end. For this reason, although one would like to change today's world back to the spirit of one hundred years or more ago, it cannot be done. Thus it is important to make the best out of every generation.

Covetousness, anger and foolishness are things to sort out well. When bad things happen in the world, if you look at them comparatively, they are not unrelated to these three things.

You cannot tell whether a person is good or bad by his vicissitudes in life. Good and bad fortune are matters of fate.

It is better not to become acquainted with men about whom you have formerly had doubts. No matter what you do, they will be people by whom you will be tripped up or taken in.

Even if it seems certain that you will lose, retaliate. Neither wisdom nor technique has a place in this. A real man does not think of victory or defeat. He plunges recklessly towards an irrational death. By doing this, you will awaken from your dreams.

In the eyes of mercy, no one should have hateful thoughts. Feel pity for the man who is even more at fault. The area and size of mercy is limitless.
