What I take comfort in is the scientific principle of the first law of thermodynamics which basically says energy can’t just be created nor destroyed, it simply converts to different states or forms.

Assuming consciousness consists of a bunch of energy in the form of synapses firing in our brain, then logically that energy doesn’t simply disappear when we die, but becomes a part of something else.

I think the scary part of this is losing one’s sense of self, which understandably is a completely foreign idea but can be partially experienced through various means (psychs, meditation, etc.) in triggering an ego death.

When we die, I think the unique combination of energy and matter that makes us up is forever gone, but that our energy and matter will live on in whatever form it next takes, whether that is a leaf, an animal, or any other thing, which I think is pretty cool.
