If there are sound reasons or bases for the points you demand, then there is no need for violence. On the other hand, when there is no sound reason that concessions should be made to you but mainly your own desire, then reason cannot work and you have to rely on force. Thus using force is not a sign of strength but rather a sign of weakness.

Whether you believe in God or not does not matter so much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life. And a good life does not mean just good food, good clothes, good shelter. These are not sufficient. A good motivation is what is needed: compassion, without dogmatism, without complicated philosophy; just understanding that others are human brothers and sisters and respecting their rights and human dignity.

Being concerned about other people is especially relevant in today's world. If we consider the complex inter-connected ness of our modern lives, how we depend on others and others depend on us, our outlook will change. We’ll begin to see 'others' not as somehow distant from us, but as people we are in touch with, people close to us; we will no longer feel indifferent to them.

When a problem first arises, try to remain humble and maintain a sincere attitude, and be concerned that the outcome is fair.

Criminals, people who commit crimes, usually society rejects these people. They are also part of our society. Give them some form of punishment to say they were wrong, but show them they are part of society and can change. Show them compassion.
