<i>We set up boundaries between creatures, define concepts like life and death because they allow us to understand and predict the world better.</i><p>I think that&#x27;s what &quot;eating the fruit of the tree of knowledge&quot; means. If the universe is unity, when you die, the universe is still here. As Christians put it, &quot;One with God&quot;. If you see yourself as separate to the universe, when you die, you&#x27;re dead. And Hell = consumed by ego, which likes comparing you and others.<p>That&#x27;s going into philosophy, and it&#x27;s useful in so far it helps people feel content.
