Maybe there are other Gods in other big bangs expanding outward.
What if the reason you cannot remember life to life, is because of your God affiliation?
Perhaps Gods are the ultimate narcissists.
There isn’t any difference between Gods and Demons, just a different direction.
Perhaps Buddha was making himself small because of the inverse. The inverse is that the smaller you get, the larger you become.
So that when you become so small, you become astronomically large as part or even all of the all.
I do not wish to become a God because I do not wish to become that narcissist.
All Gods are by their very nature are narcissists. They behave narcissistically as they choose to be involved in the lives of their worshippers and become more/larger by nature of adding them to their collective soul.
Not a pleasant thought…
I understand what is in it for a God, but what is in it for you?
Perhaps staying as a child, not having to hold the responsibility for all of your choices, desires, and acts. Not having to be an adult, a God.
For me, everything always goes back to the thought that we are all expressions (waves on the sea). Even God, Gods, Demons, etc.
All are waves (some larger some smaller) on the sea.
Heaven and hell are here right now. They live with you in this perceptive moment.
Could gods be built on collective altruism? Not likely due to God sized ego.
Some try, but it has always ended in failure (so far as we know)
