I think there are different interpretations of self godism depending on other beliefs one has. One interpretation is we are all part of God or something. Like Christians who say God is everything including us so hating anything is a sin. There is also a sort of atheist version where we are the gods of our own conscious or whatever. Something about the world around us being a hallucination of our brain based on what our sensory organs perceive. I think there is one that ties in to the belief you create your own afterlife with your last thoughts before death, like when you read a story and some Internet theorist says it was all the dream of a terminally ill coma patient on their death bed. So you can go in creative mode in your death dream as your brain shuts down and perception of time is altered according to this one. It's just some philosophy thing.
