Everything has a spirit and it's all connected. If you think about that, if you live your life by it, then you're less likely to cause any hurt. It's like how our bodies go back into the ground when we die, so that connects us to the earth. If you dump trash, you're dumping it on your and my ancestors. Or to bring it down to its simplest level: treat everything and everybody the way you want to be treated, because when you hurt someone, you're only hurting yourself.
