This is the world we have to cultivate our minds and hearts for. We need to discover shim jung, using God as the standard. If you can do this, you will be like a moon reflecting the rays of the sun. Experience love directly from God and reflect that. If you love them with your whole heart you come to feel that because you resemble them, you are good.
Children are reflections of their parents.
You see yourself by looking at your own children. It is also true that by looking at your parents, someone can see what kind of a child you are. Because of love you feel one with your parents. But if it is hatred you feel towards them, you will also hate that which resembles you, whether it is your parents, children or whatever. We take after our grandparents too.
