The 10 Indian commandments

1. Treat the earth and all that dwells therein with respect.
2. Remain close to the Great Spirit.
3. show great respect to your fellow beings.
4. work together for the benefit of all mankind.
5. give assistance and kindness wherever needed.
6. Do what you know to be right.
7. look after the well-being of mind and body
8. Dedicate a share of your efforts to the greater good.
9. Be truthful and honest at all times.
10. Take full responsibilities for your actions.

My favorite from all of these is give assistance and kindness wherever needed because you should always help someone in need. Id think the hardest one to do would be remain close to the great spirit because i think that would have to be taught since you were little. another hard one would be look after the well-being of mind and body because there are a lot of overweight people.
