'eternal life' concept

a thought went through my mind this morning, someone else's thought. i agreed with it. the idea was part of my secular religion concept. choose life, eternal life, in a secular or non-supernatural sense (secular isn't really the right word - atheistic, or 'natural' religion?), through having a large number of children, teaching them how to be beautiful and healthy, giving them a safe nurturing community, teaching them to also have many children, and passing on the beliefs and practices. your own life dies, but your children's children's lives go on, and your culture, and the ideas that matter to you. after you die, somebody else will still care about what you cared about, and will still try to accomplish the goals you were trying to accomplish. it won't be exactly the same, and everyone is unique, but you can keep a general spirit or general idea alive for many generations.
