Eric, I looked up god shaped hole out of curiosity. The explanation I read was we all have a hole in our hearts that only god can fill - nothing else will do is the idea. I say, right, uh-huh, wutev...
Some Buddhist types believe in a core of "basic goodness," presumably in the heart or gut. Similar idea in a way; they just don't call it god. They also talk about faith, but it's more like trust, a trust that things are as they are, that nothing is permanent, and thus we can experience fearlessness. Or something like that.
But no, I don't feel I have a god shaped hole, and I don't feel empty. If god is in there, I hope it's comfortable. Regardless, I ain't praying to no hole no how.
