In an email exchange today, my sister wrote, "There is a God-shaped vacuum inside all of us, and we often spend our lives trying to fill it up with everything but." This really struck me and gave me some food for thought. This vacuum is what we fill with food, drugs, sex, TV, violence--whatever it is that can keep us cushioned from our true feelings, our true experience. It can also be used to keep others at an emotional distance.
In terms of the "God-shape": if we can indeed find God within ourselves, then this vacuum is literally infinite in size and actually without shape, since the God(dess) within us is, in itself, infinite.
