Yes, yes and yes. I mean, I'm married to a physicist, but that always made sense to me from a spiritual perspective and a biological perspective. There's something very, very beautiful about knowing that we all return to the earth from which we came - and it's also an argument for taking care of the earth as well, because we are, quite literally, the earth.
As I think I said in my last post, or maybe I didn't, my Dad died last September. It brings me great comfort to know he is the ocean, the soil, the air.
