Never seek illicit wealth.

The Master said, "A true teacher is one who, keeping the past alive, is also able to understand the present."

To study and constantly, is this not a pleasure? To have friends come from far away places, is this not a joy? If people do not recognize your worth, but this does not worry you, are you not a true gentleman?

Coarse rice to eat, water to drink, my bended arm for a pillow - therein is happiness. Wealth and rank attained through immoral means are nothing but drifting clouds.

First and foremost, be faithful to your superiors, keep all promises, refuse the friendship of all who are not like you; and if you have made a mistake, do not be afraid of admitting the fact and amending your ways.

There are three friendships which are advantageous, and three which are injurious. Friendship with the upright; friendship with the sincere; and friendship with the man of much observation: these are advantageous. Friendship with the man of specious airs; friendship with the insinuatingly soft; and friendship with the glib-tongued: these are injurious.

Make faithfulness and truth thy masters: have no friends unlike thyself: be not ashamed to mend thy faults.
