All these are linked to our "idea" about death. It's easy to form a cult around what people don't understand. That's why I specifically avoided talking about life after death and put the life before death on the sidelines. I wanted to focus on the part that's most mysterious. I don't remember dying or being dead. It's an alien experience and the only way we know to conceptualize it is lack of everything there is in our lives.
Thinking and understanding this aspect of life can transform and elevate a person into a higher level. So I like the more practical aspects.
