Two Dimensions, Above All Realms

What is light? What is darkness? What does it have to do with me? Whoever can give me the power to protect the people I care about will be who I believe in. Others have nothing to do with me. Good or bad are all other people's words. I only care about the people and things I care about. Don't talk about selfishness, everyone is selfish, right?
