Twenty rules for lifelong training

Early in their formal education, young samurai were instructed to brush a copy of the following rules and then sign and date the document as a lifelong pledge. I think it also applies to tea training.

 1. Never lie.
 2. Never forget to be grateful to one's Lord.
 3. Never forget to be grateful to one's parents.
 4. Never forget to be grateful to one's teachers.
 5. Never forget to be grateful to one's fellow human beings.
 6. Do nothing to offend gods, buddhas and one's elders.
 7. Do not begrudge small children.
 8. There is no place for anger or rage in the Way.
 9. Do not burden others with your own troubles.
10. Do not rejoice in the misfortune of others.
11. Do your best to do what is best.
12. Do not turn your back on others and only think of yourself.
13. When you eat, think of the hard work of the farmers who grew the food. Never
       be wasteful of plants, trees, earth or stones.
14. Do not dress up in fine clothes, or waste time on superficial appearance.
15. Always behave properly with good manners.
16. Always treat everyone like an honored guest.
17. To overcome ignorance, learn from as many people as possible.
18. Do not study and practice the arts just to make a name for yourself.
19. Human beings have good and bad points. Do not dismiss or laugh at anyone.
20. Strive to behave well but keep good actions hidden and do not seek the praise of
      others.
