You need to be able to discern what is important from what is not. Lack of desire, proper conduct and love. Discerning what is real from fantasy. There are two types of people, the ones that know the way and the ones that do not. Knowledge is essential to help humanity. We need to stride for the path of good and oppose evil. You need to differentiate from what is right from wrong. You always need to practice good. Separate what the body wants from what you want. You need to be in control of your body and desires. Always do the right thing and abstain from doing wrong. Use common sense and reason to guide you thru the path. Distinguish what is useful and practical from what is not. Knowledge is use to develop wisdom. The wisdom is use to teach others or to help them directly. The mind and thought need to be monitor for negative emotions or ideation. Always, be truthful in words, thought and action. Do not gossip or allowed people to talk about others in front of you. Do not wish evil to others. Teach your brother the path of good-by example. Teaching others, especially children the path of evil is one of the worst thing you can do.
