I am finding this to be oh so true. My mom passed away in 2014 and I just couldn't bring myself to get rid of most of her things. I just keep shuffling them from room to room, dusting them and moving them again.
In the last couple of months I have made it a point to purge a few things each week. I think of how my mother cared for these things lovingly, and at first it was hard to get rid of them, but they were her things, not mine. With each purge I feel lighter and freer and more alive, somehow.
