The mechanics of love imply some sort of bridge between the sensual and the spiritual, sometimes to the point of deification; the notion of an afterlife is implicit not only in our couplings, but also in our separations.
There is an afterlife. I am convinced of this.
I don't believe in any particular definition of the afterlife, but I do believe we're spiritual creatures and more than our biology and that energy cannot be destroyed, but can change. I don't know what the afterlife is going to be, but I'm not afraid of it.
Losing my father made me want to find out if I could come up with a version of God or the afterlife that I could feel like was acceptable now that both my parents are in it.
