The mass of me is transformed into energy. To paraphrase Walt Whitman, look for me in a grain of rice. I will be smiling at you from a spicy tuna roll. Maybe then I will nourish you more than this article. The same is true of feelings, perceptions, impulses, consciousness.
Energy is conserved.
You can slice it and dice it, turn it into a piece of fudge, move it here and there. But the total amount never changes. What's more, for every positively charged electrical particle, there exists its negatively charged counterpart. For every Buddha, there is a Devadatta. For every Abba, there is an Eminem.
