As I prepare again to move, this thought occurred to me: "we are all renting space." In the end, none of us actually truly own anything, or any place, no matter how much we paid for them or how attached we feel. We can't take it with us. This is true of houses, cars, all our accumulated "stuff." True, if we "own" things (in a legal/financial sense), it can give us some feeling of control: we can choose what we do with these things, such as passing them on to family or others. In that sense, we are "renting" everything for a given period of time, then eventually someone else "rents" it. And so it goes, on and on.
This thought felt liberating to me, as I go through the purging process prior to each move. It is a unburdening, a releasing of the old and inviting and allowing in the new. The ebb and flow and rhythms of life.
