Our task must be to free ourselves…
by widening our circle of compassion to embrace all living creatures
and the whole of nature and its beauty.
— Albert Einstein
To grow and maintain ourselves, we eat, drink, and breathe. The molecules we ingest have been elsewhere. Even before that, they were in different forms. The atom of carbon we eat in corn might have been, at one time, part of the carbon dioxide that was exhaled by dinosaurs that once roamed this Earth, or part of the body of Jesus or Gandhi or your pet dog. Even in our physical state, we are part of others, they are part of us, and we cannot clearly disassociate ourselves from the rest of the world.
If you knew that the stranger at the soup kitchen had atoms in her body that were once yours, would you feel differently or be more compassionate?
